Sleepyhead Publisher's Summary
The police aren't making much progress in their hunt for the killer until he appears to make a mistake: Alison Willetts is found alive and D.I. Tom Thorne believes this error will enable them to track him down. But it was the others who were his mistakes: he doesn't want to take life, he just wants to put people into a state where they cannot move, cannot talk, cannot do anything but think.
When Thorne, helped by the neurologist looking after Alison, starts to realise what he is up against he knows the case is not going to be solved by normal methods; before he can find out who did it he has to understand why he's doing it.
