Thanks to a heart transplant, former FBI agent Terry McCaleb is enjoying a quiet retirement, renovating the fishing boat he lives on in Los Angeles Harbour. But McCaleb’s calm seas turn choppy when a beautiful woman comes visiting his dock. From her McCaleb learns a terrible truth: that the heart beating in his chest belonged to her sister, who was not killed in an accident - as he’d been told - but murdered. Reactivating his connections and his expertise in crime scene interpretation, McCaleb embarks on a private investigation of his donor’s murder. Shred by shred he picks over the evidence in a search that will lead him eventually to a killer as audacious as he - and a crime more horrific than anything he ever encountered as a serial killer investigator for the FBI.
