The Schizoid Earth

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.
