Lie Down With the Devil

In Barnes's utterly compelling 12th mystery to feature Boston PI Carlotta Carlyle (after 2006's Heart of the World), Carlyle is still engaged to her mob-associated fiance, Sam Gianelli, though she's waiting for Sam to explain why he's disappeared in the wake of rumors linking him to a dead girl. Then a woman calling herself Jessica Franklin visits Carlyle armed with [...] a doubt about his fidelity. After Franklin becomes the victim of a hit-and-run, Carlyle is the most likely suspect. When the police discover that Jessica Franklin is an alias, Carlyle, in more trouble than ever, turns to her old friend and former boss at the Boston PD, Joseph Mooney.
