“Terrific! . . . Smart, and cinematic, this entertaining page-turner is so knowingly authentic only a genuine cop turned storyteller could have written it.” —Hank Phillippi Ryan, Agatha, Anthony, and Mary Higgins Clark award–winning author of One Wrong Word

When the body of prominent Portland attorney Paul Ramsey turns up in the bottom of Casco Bay, following his loss of a multimillion dollar civil trial, Byron knows it’s no accidental drowning. Golden boy Ramsey had a dark side—and Detective Sergeant John Byron believes the key to solving his murder lies in uncovering those secrets someone wanted buried along with him. 

With the brilliant Detective Diane Joyner by his side, Byron takes on Ramsey’s former employer, the powerhouse law firm of Newman, Branch & DeWitt. But delving further into the troubled waters of Ramsey’s past only serves to lengthen the list of suspects—unleashing a perfect storm of corruption, betrayal, and murder that only Byron can stop. If he’s not too late.

“When a lawyer who’s already antagonized half the people in Maine winds up dead, every pine tree in Portland seems chock-full of suspects. . . . A sturdy, starchy police procedural.” —Kirkus Reviews
