"Doctor.....are you saying you are not sure of something?"
Mrs Constance Clarke has faced perils on many planets, but now she finds herself in the most dangerous place on Earth. A place like home, yet terrifyingly different, where ordinary decent folk might hand her over to a dreadful fate. And as night falls, she and the Doctor realise that something is on the prowl outside, a creature darker than the dark. And hungry...
The Darkened Earth is my first encounter with Constance Clarke (Miranda Raison - also Tallulah in Daleks in Manhattan and Evolution of the Daleks), and I must say, what a wonderful companion she makes. Constance is clever, confident and a perfect foil for the sixth Doctor. Her plummy vowels and old-fashioned virtues are a breath of fresh air.
The story sees the Doctor and Constance arrive in what they think is a rural post-war Britain when in reality this couldn't be further from the truth. After a slight glitch with the TARDIS's translation circuits, they realise they are in Germany, at the very height of the war. Not only do they need to dodge British bombs, but also a terrifying creature that feasts on whatever light can be found.
John Pritchard's writing is tense and fast-paced. Constance is a serving WREN, and to put her behind enemy lines with a frightened family during a blackout is a very interesting plot twist. There would have been more than enough story farmed from this one idea, but add to this a creature that is stalking the darkened streets seeking light energy to feed upon, and you have a proper corker of a story that I can't recommend enough.
