A dark and twisting thriller from the master of psychological suspense, New York Times No. 1 bestseller Jonathan Kellerman, author of KILLER and BREAKDOWN. Perfect for fans of the thrillers of Harlan Coben and Michael Connelly, 'OVER THE EDGE is a compulsive page-turner . . . filled with insight, charged with suspense, and laced with just enough humour to make the whole thing sparkle. This one is simply too good to miss' (Stephen King).

Jamey Cadmus is clearly a deeply troubled young man. Found clutching a bloodied knife at the scene of a brutal double homicide, surely he must be the vicious serial killer who's been terrorising LA. What other explanation can there be? The public are demanding the death penalty but his lawyer is pleading diminished responsibility.

Psychologist Alex Delaware is asked to make an assessment of Jamey's mental health but to do that he needs to look into Jamey's past and no one wants Alex digging there . . .
