Nicci French’s first Frieda Klein mystery, Blue Monday, won rave reviews everywhere—from People magazine to the New York Times Book Review—and earned comparisons to bestsellers by Kate Atkinson and Laura Lippman. In Tuesday’s Gone, the solitary London psychotherapist returns in a brilliant thriller even more twisted than the last.

On a routine home visit, a London social worker discovers her psychotic client serving tea to a naked, decomposing corpse. Unable to make sense of the woman’s confused ramblings, Detective Chief Inspector Karlsson asks Frieda Klein for help uncovering the dead man’s identity. Frieda soon learns that he was a notorious con man—one Robert Poole. But Frieda can’t help feeling that Poole was killed to embroil her in the investigation, that her past isn’t done with her yet. And if so, is Frieda herself the next victim?
