Detective Harry Bosch is back on the job and working on the hottest murder investigation in Hollywood. The body of a movie producer has been found stuffed into the trunk of his Rolls, and to Harry the evidence seems to say it all: it’s "trunk music", a Mafia production. The money trail leads from L.A. to Las Vegas, and Harry’s determined to get to the bottom of things – but he’s making some powerful enemies along the way. And, as if he wasn’t knee-deep in trouble already, he’s about to take the biggest gamble of all – on love. Mixing business with pleasure: it’s the kind of parlay that could drive Harry to distraction…and into an early grave, Vegas-style.
