There can be no doubting Patrick Ness’s credentials as a writer of YA fantasy, and this Puffin series continues to add ‘big name’ authorial value to its month-by-month releases. Reaching the fifth Doctor’s tenure, Tip of the Tongue features Nyssa as the Doctor's sole companion, also including some smart continuity references to Adric and Tegan near its conclusion.

Ness excels at creating fantasy worlds. Here it’s America in 1945, but very much with an alien twist. Strange creatures dubbed 'Truth Tellers' (which attach themselves to their recipient’s tongue) have invaded Temperance, Maine, meaning that locals can indulge themselves in expressing plenty of plain, unvarnished reality. Of course, Ness can’t resist having some fun with this concept, working in a version of a “does my bum look big in this?” gag, but he also strikes a more serious note by illustrating just how much society hinges on degrees of tact, if not innumerable white lies. Constant truth-telling offers a ready way for veracious intruders to disrupt human existence, it would seem.

Appropriately enough, Ness withholds the full truth of his own tale, and as a result there’s a satisfying twist towards the end of proceedings. He relies on his readers’ sense of what constitutes a Doctor Who story (e.g. extraterrestrial threat) to misdirect and mislead, and the “Dipthodat” race are ultimately not quite what you might have expected… If economy with the truth gives rise to a clever denouement, there is nevertheless a danger that this doesn’t always feel exactly like Doctor Who. It’s more of a scenario which the Doctor happens to breeze through, with our celery-sporting hero reduced almost to a guest-star role. Ness is far more interested in his own original characters and their relationships, focusing on the friendship between young Jonny and Nettie rather than centring events on the Doctor and Nyssa (even if the latter’s trousers cause a bit of a stir in 1945 Maine).

Last month’s Roots of Evil simultaneously captured the flavour of fourth Doctor-Leela adventures and conveyed Philip Reeve’s authorial voice, whereas this time round we get more of a character study, and a carefully thought-out, localised transformation of history, but not something which necessarily fits snugly into the Davison era. Instead, Tip of the Tongue skillfully combines its truth-telling theme with a coming-of-age tale, where the reality of the human heart becomes something subtle and malleable – something not fully in the grasp of its teller – rather than a mere matter of reportage. Ness makes us care about Jonny and Nettie, and with more than a hint of “new Who” permeating the turn of events, emotional realism becomes just as important here as the matter of an alien incursion.

Ultimately, Tip of the Tongue contradicts its title; unlike a word that’s almost remembered, yet can’t quite be recalled, this material is always under its author’s control, and it’s a beautifully crafted piece of fiction - a good story first and foremost, and a Doctor Who story second, as if viewed from the perspective of somebody who would usually be a bit-part character. And where child actors can sometimes pose a problem for televised Who, no such difficulties plague the written word. Young characters come into their own in this deft integration of YA fiction and the Whoniverse.

To be sure, Patrick Ness hasn’t written a novella which simply apes family entertainment TV, nor one which offers unbridled SF spectacle in literary form. And, unusually, fan service is almost an alien concept here (bar a few moments of continuity referencing, and the fifth Doctor’s attitude towards travelling companions). But perhaps the most compelling form of “fan service” lies in creating a thematically coherent, intelligent and consistent story-world that never feels programmatic. Tip of the Tongue isn’t a “game changer”. It doesn’t promise any big secrets or any devastating reveals. Yet, perhaps unwittingly echoing Peter Davison’s portrayal of the Doctor, this month’s Puffin ebook combines quiet integrity with true warmth and charm.

Philip Reeve has won many awards across his writing career to date, and reading this month’s e-short it’s easy to see why. As well as effortlessly capturing the spirit of a fourth Doctor and Leela story (it feels like something developed by Hinchcliffe and Holmes but made by Graham Williams… with a budget), Reeve’s own authorial voice also rings out loud and clear. When ‘name’ authors work on non-TV Who there can sometimes be a tussle between different incarnations – will it be a Michael Moorcock novel, or a Doctor Who story, for instance. But in this case, there’s a seamless integration of something that’s at once very “Reevian” but also contains dialogue which wouldn’t feel out of place in a classic Chris Boucher script. Leela’s curt explanation of what a scarf is, for example, offers up particular humour. And perhaps as a nod to the Sevateem there’s something intriguing and very unexpected about certain character names…

To call this a partial compositing of ‘Planet of Evil’ and ‘Face of Evil’ does it a disservice; the world swiftly and colourfully sketched in by Reeve would have been tricky to realize in the 1970s TV show, and it really belongs to written Doctor Who. It has the same coherent inventiveness which marked out Reeve’s Mortal Engines – but where that introduced mobile cities, this has the “Heligan Structure”, a tree that's grown into a kind of "wooden space station". And there’s an entire accompanying culture set out for readers, whether it’s the Heligan’s “heartwood”, “digestion chamber”, or “trunk-roads”. Reeve has fun naming his world’s tangled arboreal features – the Heligan’s bark has plenty of bite – but he also acutely captures Tom Baker and Louise Jameson’s performances. There are moments of description which resonate with Baker’s joyous inhabitation of the role, particularly a focus on that infamous, life-affirming grin.

All the language games with tree-like features and attributes – plenty of copse markers, one might say – make this sound like a very fantasy-oriented tale, riffing insistently on a single set of ideas. But Reeve also branches out into sharply observant character moments such as Leela missing the woodland of her own planet, as well as linking the oxygen-producing capacities of the vast Heligan Structure to one of SF’s staples, namely terraforming. With the Doctor and Leela being well served, poor K-9 remains very much the unwanted tree decoration on this occasion, left in the TARDIS to charge up his batteries. Perhaps this makes sense in a novella, however, as it means there are only two lead characters to follow, whilst also avoiding questions of K-9’s mobility on a tree-world, not to mention whether his laser would’ve promptly burnt the whole place down.

Given recent speculation over which actors might or might not be appearing together in the fiftieth anniversary TV special, Roots of Evil has a rather canny structure which at least allows the fourth Doctor to express clear views on his eleventh incarnation. They might not meet, but their paths cross glancingly in this adventure, albeit sufficiently for the Baker Doctor to express some trenchant views on whether certain items of clothing are “cool”. And Leela also has a view on the future Doctor, as aspects of the show’s current format fleetingly intertwine with retro gothic stylings. The sonic screwdriver is even retconned into line with facts established by Steven Moffat, as two eras of Who are brought into dialogue, and tendrils of connection are lightly stretched across the programme's family tree.

Reeve paces his tale incredibly well. We get clever back story, a well-crafted and believable alien society, a lunatic villain for the Doctor to spar with, and some great monsters – all without events feeling too rushed. The monsters, although perhaps being slightly predictable in form and function, are still smartly depicted, carrying a requisite sense of mulched menace.

Roots of Evil is by far the best Puffin e-short to date. This really is a five-star adventure for the fourth Doctor, and hopefully later contributors to the sequence will take a leaf out of Philip Reeve's book in terms of intelligently balancing authorial style with authentic Doctor Who.

Summer Falls is a curious novella, more ‘Doctor fic’ than ‘Doctor lite’, since it’s supposedly written by Amelia Williams (formerly Pond) and involves a lightly fictionalized version of her Doctor. The ‘Curator’ has a mysterious “shed” in place of a Police Box, says very Doctorish things like “magic is cool” and “I love a little shoppe”, and is highly knowledgeable about all sorts of unusual entities and events. Oh, and the Curator also has a sort-of companion: one of the most brilliant, amusing companions that we’ll never get to see on-screen. No, it's not a shape-shifting talking penguin, but rather a grey talking cat, which enables real-world writer James Goss to explore all manner of great cat jokes. Essentially, what we learn is that cats do not fit at all well into the template of a Doctor Who companion, particularly given their tendency to get comfy and warm and have a doze mid-adventure, or their need to start cleaning rather than answering a question.

Returning to thoughts of Amy Pond strikes me as a faintly curious thing to do just as a new companion and a new mystery are launched in the TV series. Having Clara Oswald refer to an Amelia Williams’ story could be read as a passing of the baton; a way to honour and remember what’s come before as the franchise moves remorselessly on (and where everyone’s replaceable – not just companions, but even executive producers and showrunners). Perhaps this particular tie-in offers a kind of reassurance to fans of the Ponds. Amy hasn’t been erased from Who, after all, and the show is allowed to remember her in its passing details. Either that, or there’s method to the reminiscence, and Steven Moffat doesn’t want audiences to forget Amelia for a specific, yet-to-be-revealed reason. Given that ‘The Angels Take Manhattan’ was so insistently book-ended, circling back to ‘The Eleventh Hour', for this story/character thread to be picked up again so soon feels strange at the very least.

For my money, James Goss has consistently been one of the best recent writers of original, off-screen Doctor Who and Torchwood, and there's a tendency towards playful pastiche evident across his work. He’s a strong choice for this sort of material, given that Summer Falls was supposedly first published in 1954, and so is tailored to resemble a quaint, mildly jolly-hockey-sticks children’s fantasy adventure. Not only does it not feature the Doctor (by name), it’s also strongly fantastical rather than science-fictional, a genre shift which Who itself occasionally indulges in, but which seems to have dismayed some audiences of late with regards to ‘The Rings of Akhaten’. Although Summer Falls has the Doctor-type character muttering about “psycho-temporal” factors, it doesn’t really make very much effort to pin matters down into a science fiction template, instead preferring the broader poetic license of talking cats, frozen seas, and strange, powerful objects which have to be collected.

Goss repeatedly toys with readerly expectations. Summer Falls features the Lord of Winter, which in a novella released shortly before ‘Cold War’, and not long after ‘The Snowmen’, one might guess would implicate either the Ice Warriors or the chilly Great Intelligence. What we get remains tantalizingly vague, and I’m not at all convinced that this tale ties into ongoing series 7 events in any unexpected way. Of course, the big gimmick is that Summer Falls appeared on screen in ‘The Bells of Saint John’, meaning that we’ve already seen its heroine Kate depicted as a Spoonhead, as well as knowing that Chapter 11 is a tear-jerker (something it strives to live up to). This creates a complex layering of fiction-upon-fiction: the real book that you can buy and enjoy is itself part of the Doctor Who universe, as well as featuring a fictionalized version of the Doctor. When will Clara ask the Time Lord if he’s really the Curator? Will this fiction-within-a-fiction be played with in the TV show itself, I wonder, even perhaps in its anniversary special? I’d hazard not, however: the reference-spotting of Summer Falls suits fandom all too well – it’s a sort of roman à clef revolving around a key which has to be found, while readers can use the master key of Doctor Who to interpret what’s going on. But I’m not convinced that such "meta" would necessarily translate well to the broader mass audience of Christmas and Anniverary Specials, so perhaps ‘Doctor fic’ will remain a little-known tie-in subgenre for now.

Having said that, I’d like to see a series of Amelia Williams’ tales, perhaps written at different times across her life, each giving a different refraction and revision of her adventures. Re-fictionalized alt-Daleks or Screaming Cherubs could get an outing. Pursued as a series of reimagined slants on the Moffat era, this sort of playful Who manqué could start to build up into far more than the sum of its parts. But as things stand, and as a one-shot, Summer Falls is a clever, cool experiment in meta that doesn’t always feel like it really matters to ongoing arcs and questions.

When I was a teenager, in the late 1990s, for a while I had an after-school paper round, delivering copies of the Brighton-based Evening Argus around my village in Sussex. It was never a paper of choice in our family, but while I had the round we used to buy a copy, which I would often peruse after I’d finished delivering the others.

I can distinctly remember noticing the features by John Nathan-Turner, an instantly recognisable name to any Doctor Who fan. He was a familiar figure from documentaries such as More Than Thirty Years in the TARDIS, and I’d read his memoirs serialised in DWM not long before. With a name like that it couldn’t be anybody else, and he even had his own byline photo to confirm it.

His features in the Argus were interviews with minor local celebrities, usually actors. I don’t remember how many of them he did – Richard Franklin is the only one that I specifically recall – but I do very clearly remember thinking, and even saying to my dad, “That’s a bit sad, he used to produce Doctor Who – how come he’s ended up writing cheap showbiz features for a local paper?”

As JNT: The Life and Scandalous Times of John Nathan-Turner reveals, the whole of Nathan-Turner’s post-Doctor Who career, which has perhaps been something of a mystery to fandom, could be described as being “a bit sad”. His name had become mud at the BBC, and despite a series of increasingly desperate and bizarre pitches, he was never able to persuade any broadcaster to work with him again, or to take up any of his programme ideas.

Richard Marson has done excellent work with this book, delving into the life and career of a man who seems utterly familiar on the one hand to Doctor Who fans, but who really it seems we only ever knew a certain side of, in a certain way. It’s the tragedy of many who are associated with Doctor Who that they are remembered only by us, and only for their Doctor Who careers – but Nathan-Turner’s association with the show became a burden even while it was ongoing.

Marson, a former producer and then editor of Blue Peter, himself points out the parallels between himself and his subject – both producers of long-standing, iconic BBC television series, who ended up having somewhat bitter partings from the programmes they had loved. But just because Marson has some empathy for Nathan-Turner, don’t make the mistake of thinking this book ever strays into the territory of being a hagiography – indeed, as you may have noticed from some of the press attention it has garnered, it’s anything but.

The fact that Marson is unafraid to tackle head-on some of the less pleasant aspects of Nathan-Turner’s character – and, to a greater extent, those of his partner Gary Downie – caused argument and debate in fandom in the weeks before the book was even released. There are some who are appalled by the revelations in the book. Some who are appalled that accusations have been made against men who are no longer alive and unable to defend themselves. Some simply embarrassed that Doctor Who has become associated with such squalor in its anniversary year, and particularly in the wake of the wider scandals that have engulfed the BBC in recent months.

It’s true that this book would almost certainly not have been written, at least not in this way, while Nathan-Turner and Downie were still alive. But that’s probably true of almost any honest biography, and time and distance can help to lend a vital objectivity. While it’s also true that the book contains details some Doctor Who fans may find unpleasant reading, in the same way that the book is not a hagiography, it’s never a hatchet job either. Marson is scrupulous in reproducing as many points of view and versions of events as possible, putting quotes from various interviewees one after the other to offer all the different sides of an argument, or versions of events.

The reader is left to make up his or her own mind about Nathan-Turner. Myself, I was chiefly left with the impression of a man I personally wouldn’t have ever wanted to know, but at the same time also a man rather sadly crushed by circumstances, and by a changing world at the BBC.

‘The BBC’ – dangerous as it always is to regard it as a single-minded monolith – almost comes across as a personality and a character in its own right in the narrative, and how interesting you find the book may depend on how much of an interest you have in the internal workings of the drama department, in the days of multi-camera videotape drama being made at Television Centre. I personally find such things fascinating, and it’s a real treat to get an insight into the labyrinthine workings of the Corporation and its drama department in the 1970s and 80s. It’s fair to say, however, that others may find such things less involving, and if you’re not really enthused by the structures and workings of the BBC drama department then this is possibly not the book for you.

Doctor Who fans generally, however, do tend to be interested in the behind-the-scenes workings of the show they love, perhaps more so than fans of any other television series. It’s why Doctor Who is quite possibly the most well-documented television programme ever made and why, as Russell T Davies once pointed out, in generations to come it will be the case study for how British television drama was made.

You sometimes have to remind yourself when reading this book that the fans do actually love the show, however. There are times when fandom comes across as being utterly repulsive and full of unpleasant people. I realise this isn’t entirely representative of how fandom was in the 1980s any more than the worst bitchers and moaners of Gallifrey Base or Roobarb's Forum represent it now, but I have to say I am rather glad I wasn’t old enough to be anywhere near fandom at the time. We perhaps don’t always appreciate how lucky we are in the 21st century, when fandom is so much larger, and online. If there’s a particular website or group of people you can’t get on with, you can easily find another place to share your love of the show, with people and things that make you laugh. No longer do you simply have to put up with whoever happens to attend your local group meeting.

Doctor Who and fandom recovered from the – at times – dark days portrayed in this book. But the shame of it is that Nathan-Turner never got the chance to. But on the other hand, I think he would have been pleased that he’ll be remembered, and that’s where the curse of Doctor Who is at least paying him something back. Jonathan Powell – refreshingly honest as an interviewee here – may well have been a far superior drama producer to Nathan-Turner, with a track record the latter couldn’t hope to match. He’s produced several BAFTA-winning productions of high quality. But he’ll never have a biography written about him. Nobody will ever research his life in detail, track down and speak to his teachers and schoolfriends. Trace the progress of his career in television, from the studio floor to the producer’s chair. When he dies, it will be little-noted outside of his friends and family.

Doctor Who can destroy careers. But Doctor Who fans remember. And because Doctor Who fans tend to be creative and industrious, we end up with superb books like this one. It’s not always an easy read, but I would recommend The Life and Scandalous Times of John Nathan-Turner to anyone with even a casual interest in television history in general, and Doctor Who’s history in particular.

Marcus Sedgwick’s ebook entry in this series of short stories from Puffin Books is a fluidly written and gripping page-turner (or should that be page-advancer?). It captures the third Doctor’s era pretty well in many ways, almost finding time to fit in a spot of ‘capture, escape and capture’, as well as pitting the Doctor and Jo Grant against one of their textbook enemies. There’s even a cameo from Brigadier Lethbridge-Stewart, though otherwise UNIT has relatively little to do. Sedgwick has fun creating story possibilities out of the Doctor’s Time Lord constitution, and The Spear of Destiny develops an interesting take on what having two hearts might mean for body temperature and its regulation.

The titular Spear (which pierced the body of Christ at his crucifixion, had links back to the Viking God Odin, and was supposedly possessed by Adolf Hitler) makes for a great MacGuffin, the story being set in motion by its appearance in 1970s London. Sedgwick cleverly integrates bits of real-world myth, rumour and mysticism into his tale, though it never feels too overloaded by research. The Doctor sets off on a mission to capture the Spear, suspecting it to be a “PTN” (or Physical Temporal Nexus), an acronymic entity that the Time Lords want contained so as to prevent its infallible power interfering with the time-lines.

Sedgwick’s plotting creates a few difficulties, however, because he has the Doctor deciding to pop back in time and fix the Spear problem before he and Jo first encounter it in London. This creates a potential paradox at the heart of proceedings: if the Doctor and Jo succeed in their mission to neutralise the dangerous Spear, then surely the spearhead they initially tangle with shouldn’t pose any problems in the first place, having already been dealt with. To be fair, Sedgwick is alert to this issue, inserting a get-out line. But one implication of this story structure is that the third Doctor seems more than a little slapdash in his approach to a supposedly lethal artefact. Another victim of the compressed word count is that we get no backstory for the PTNs, and these remain wholly without context or explanation. Perhaps another of these anniversary stories will revisit the matter, but I wouldn’t bet on it.

The Doctor’s fondness for Josephine Grant is testified to on a number of occasions, and their relationship is nicely represented here. There’s no doubting the special degree of care and concern that this Doctor feels for his companion, nor Jo’s pride in accompanying him on his travels.

The Spear of Destiny is eventually resolved thanks to a Doctor Who continuity detail. We don’t quite veer off into fanwank territory, but Sedgwick’s closing gambit still feels a little bit pat as a way of tying up loose ends, and the adventure arrives at a rather comfortable, predictable end point; its cast of characters pretty much left in their default positions.

For me, these Puffin short stories are getting better with every installment. The sharpest thing about The Spear of Destiny is the way that it begins with the everyday, or at least with the ordinary – the Doctor and Jo visiting a museum exhibit – before whirling away into time-travel to explore the historical roots of the museum piece they’ve been investigating. As an educational detour this may well tutor younger readers. But more than that, Sedgwick playfully gestures at the wonders and mysteries of cultural treasures surrounding us in the here and now, piquing readers’ interest in history through its present-day traces. Some might say that Doctor Who’s raison d’etre is to make the ordinary fantastical and terrifying (mannequins or dolls or maggots), but this short story makes the ordinary fascinating, deploying its spearhead from time as a way into the value of museums, history, and knowledge. Unlike today’s televised Who there are no strikingly memorable monsters on show (presumed to be “what children want”). Instead, travelling into history – from glass cases to real places – is attraction enough, and Sedgwick’s writing energetically brings that appeal to life.

The second of Puffin’s e-shorts, this story focuses on the second Doctor and Jamie McCrimmon. At times it reads rather like Lovecraft lite: Howard Phillips Lovecraft’s own short story called ‘The Nameless City’ was published in 1921 and dealt with ancient ruins sung of by the (fictional) Necronomicon's "mad poet."

The Necronomicon also makes an appearance in Michael Scott’s story, and his beaked, clawed and octopus-like monsters are reminiscent of the Cthulu Mythos. I wonder just how appropriate these Lovecraftian debts are: when the TV series threatens to become ‘too scary’ for young viewers then negative commentary never seems far away, but perhaps different rules apply to the written word rather than the visual image. In any case, readers don’t have to know Lovecraft to follow the story: it’s more a bonus layer of meaning for those who get the references.

On the whole, then, this is a deft mix of Lovecraftian elements and Doctor Who history: Jamie meets a mysterious bookseller named Professor Thascalos who is presumably a well-known character drawn from the Doctor’s past (and future), whilst Vengeance on Varos’s Zeiton-7 forms a further part of events. And the second Doctor is typically well represented via a scattering of iconic dialogue and artefacts: “ when I say run, run” gets an outing, for instance, as does the Doctor’s recorder playing.

If this anniversary series partly retools Doctor Who for today’s younger readers, another emerging pattern seems to be that these ebooks make heavy use of other fantastic literature. Last month’s title was ultimately indebted to a very famous children’s fantasy, whilst this story focuses on connections to Lovecraft’s cosmic horror, and begins in 1968 on Charing Cross Road, itself renowned for its range of second-hand and collectors’ bookshops. It’ll be intriguing to see whether this bibliophilic, bookish strand continues through later e-shorts, but such is its prominence in Eoin Colfer’s A Big Hand For The Doctor and here, it’s tempting to suppose that “include elements drawn from well-known fantasy literature” was part of Puffin’s brief to writers. Time will tell whether such a device does indeed tie the whole sequence of short stories together, or whether it’s just a first and second Doctor coincidence. (Will Charlie Higson pop up with an Ian Fleming-influenced third Doctor story? Which Doctor should be re-worked via H.G. Wells or Jules Verne?).

Michael Scott doesn't just emulate Who, he also improvises a few new tunes using the show's established elements. Particularly striking is how the Doctor looks out of the TARDIS’s Police Box windows at one point, given that unlike latter-day Doctor Who, the TARDIS of this era didn’t include Police Box doors as part of its console room set-up. And the TARDIS’s organic nature, emphasized in ‘new Who’, is also cleverly seeded into Scott’s scenario.

There’s a recurring sense that this short story wants to introduce readers to the pleasures of culture beyond television. As well as featuring Charing Cross and its bookshops, the TARDIS materializes at the back of the National Portrait Gallery, and Jamie doesn’t just muse about how big the TARDIS interior is, he wonders “how many rooms, galleries, museums and libraries” it contains. Here there may be shadowy schemes and terrifyingly powerful forces from beyond time, but there are also books and galleries and music threaded into the story’s background and foreground alike. It’s Doctor Who coded as a culturally edifying vehicle. With freaky monsters. And the Book of the Dead.

One difficulty with the short story form is that there’s relatively little space and time available to set up and resolve an epic adventure. Consequently, the Doctor’s scheme to defeat an ancient evil existing before Gallifrey is only given minor foreshadowing, and seems to emerge almost out of nowhere. Nevertheless, I can imagine the story’s ending appealing both to younger readers and to admirers of Jamie McCrimmon. And curious conclusions have a long track record in official, original Doctor Who literature, going all the way back to 1960’s Doctor Who and the Invasion from Space, where galactic invaders were foiled in a truly absurd fashion. By comparison, Michael Scott’s storytelling is far stronger, artfully weaving together Lovecraft and loved continuity, even if his finale does strike a slightly off note.

A notable improvement on January’s ebook, this feels much more like Doctor Who, and Scott’s representation of the second Doctor comes far closer to deserving the description “as seen on DVD”. However, with the appearance of Professor Thascalos, and the TARDIS apparently being stranded on Earth, there’s also a definite flavour of the following era: this is very much the second Doctor retroactively composed in the light of what’s to come. Perhaps Scott’s preferred era is really that of the third Doctor, and he just couldn’t resist smuggling in a few series-travelling tropes ahead of time. (Or may be he was expecting to write a Pertwee story, and got bumped up the schedule). But whether it’s coloured by passion or pragmatism, The Nameless City is a definite credit to Scott’s authorial name, skillfully bridging Doctor Who’s eras and offering up a smartly intertextual, atmospheric tale.
