LOUISE PENNY says the Frieda Klein novels are "fabulous." JOSEPH FINDER says they're "in the rich vein of Kate Atkinson." And TAMI HOAG calls them "truly unique." A decade ago, psychologist Frieda Klein was sucked into the orbit of Dean Reeve — a killer able to impersonate almost anyone, a man who can disappear without a trace, a psychopath obsessed with Frieda herself. In the years since, Frieda has worked with — and sometimes against — the London police in solving their most baffling cases. But now she's in hiding, driven to isolation by Reeve. When a series of murders announces his return, Frieda must emerge from the shadows to confront her nemesis. And it's a showdown she might not survive. This gripping cat-and-mouse thriller pits one of the most fascinating characters in contemporary fiction against an enemy like none other. Smart, sophisticated, and spellbinding, it's a novel to leave you breathless.
