Stuart Neville, “the current master of neo-noir detective fiction” (Boston Globe), is back with a chilling new thriller Belfast, Northern Ireland: Rea Carlisle has inherited a house from an uncle she never knew. It doesn't take her long to clear out the dead man's remaining possessions, but one room remains stubbornly locked. When Rea finally forces it open, she discovers inside a chair, a table—and a leather-bound book, its pages filled with locks of hair, fingernails: a catalogue of victims. Horrified, Rea wants to go straight to the police but her family intervenes, fearing that scandal will mar her politician father's public image. Rea turns to the only person she can think of: disgraced police inspector Jack Lennon. He is facing suspension from the force and his new supervisor, DCI Serena Flanagan, is the toughest cop he's ever met. But a gruesome murder brings the dead man's terrifying journal to the top of the Belfast police's priority list.
