Tuesday’s Gone - Nicci French

When a decomposing body is found in the flat of Michelle Doyce, a woman who is plainly deranged, the police call in psychotherapist Frieda Klein. They need Frieda to help Michelle identify the corpse. But the name Frieda eventually uncovers is that of a master conman whose victims turn out to be as numerous as the possible motives for his murder. The police need Frieda to figure out who might be telling the truth – or lying – as they draw closer to identifying the killer. But someone is determined to silence her … and will stop at nothing to do so.
