When bestselling thriller writer Andrew Danner wakes up in a hospital bed with no idea how he got there, he is horrified to be told that he is responsible for the murder of his ex-fiancée.

In the resulting trial, Drew is exonerated on the grounds of temporary insanity caused by a recent brain tumour. But he still has no idea if he really did kill Genevieve. Then another woman is discovered dead, murdered in the same way.

Trying to clear his name and understand what's happening to him, Drew enlists the help of a tame forensic scientist, a sympathetic detective, his staunch friend Chic, and an over-confident teenager. Can Drew discover what really happened that night and unmask the real killer?

A gripping thriller from the bestselling author of Richard and Judy selections Orphan X and You're Next.
