Lethbridge-Stewart was supposed to be in the mountains of the east, but things didn't quite go according to plan.On the eve of war, something appeared in the sky; a presence that blotted out the moon.Now it has returned, and no battle plan can survive first contact with this enemy.Why do the ghosts of fallen soldiers still fight long-forgotten battles against living men?What is the secret of the rural English town of Deepdene?Lethbridge-Stewart has good reason to doubt his own sanity, but is he suffering illness or injury, or is something more sinister going on?Plagued by nightmares of being trapped in a past that never happened, Lethbridge-Stewart must unravel the mystery of a man ten years out of his time; a man who cannot possibly still exist.This is the second book in a brand-new series of novels set just after the Doctor Who serial The Web of Fear, featuring the characters and concepts created by Mervyn Haisman & Henry Lincoln.
