From the international bestselling author comes yet another gripping novel that paints a brutally vivid picture of a killer's mind. An edge-of-your-seat thriller, for fans of Lee Child and Peter May. 'A pulse-pounding serial killer thriller' Publishers Weekly 'Cleave uses words like lethal weapons' New York Times Book Review People are disappearing in Christchurch. Cooper Riley, a psychology professor, doesn't make it to work one day. Emma Green, one of his students, doesn't make it home. When ex-cop Theodore Tate is released from a four-month prison stint, he's asked by Green's father to help find Emma. After all, Tate was in jail for nearly killing her in a DUI accident the year before, so he owes him. Big time. What neither of them knows is that a former mental patient is holding people prisoner as part of his growing collection of serial killer souvenirs. Now he has acquired the ultimate collector's item - an actual killer. Meanwhile, clues keep pulling Tate back to Grover Hills, the mental institution that closed down three years ago. Very bad things happened there. Those who managed to survive would prefer to keep their memories buried. Tate has no choice but to unearth Grover Hills' dark past if there is any chance of finding Emma Green and Cooper Riley alive. For fans of Dennis Lehane's Shutter Island, Thomas Harris' Silence of the Lambs, and Jeff Lindsay's Dexter series, Collecting Cooper is another 'relentlessly gripping, deliciously twisted, and shot through with a vein of humor that's as dark as hell' (Mark Billingham) novel by this glimmering talent in the crime thriller genre.
