Every choice is a compromise. And every compromise changes who you are. For the better. Or for the worse. And some choices can turn your heat black.After body parts wash ashore in Florida, Det. Becker Gray finds himself interviewing a killer who holds information that stretches far beyond this investigation. And he'll share it with Gray ... for a price: a promise. A choice, a compromise, a change that may turn his heart black.After body parts wash ashore in a tranquil Florida beach town, investigators quickly identify the killer, Kenneth Lamont Duncan. However, Duncan won't talk to anyone but Detective Becker Gray. Duncan's demand seems bizarre. It's been seven years since the two men spoke or were even in the same room together. And Gray hardly remembers the specifics of that encounter. In the fourth installment of the Becker Gray series, the detective's interview with Duncan winds through the killer's seemingly tenuous grip on reality. Truth morphs into lies. Clarity fogs. And the men's differences become their commonality. All part of Duncan's plan: manipulation of the information, the promise Gray pledges, and even the bloody ending.
