Greg Abimbola is many things. He's Black, British and fluent in Russian. He's a snappy dresser, a reasonable teacher, and an unenthusiastic sports fan. But most of all, he's exceptional at keeping secrets. Like, who he really is, and the things he's done. Determined to keep his head down after helping solve a murder in the school basement, Greg fears a trap when Sergeant Rachel Lev of the Pittsburgh police corners him in his apartment. Because his refusal to take credit isn't modesty, it's a survival tactic. But Rachel is here on another matter entirely. She needs his help. She's lead detective on the homicide of an unidentified man fished from the Allegheny River. With clues scant, and surrounded by colleagues who'd love to see her side-lined, Greg is her final roll of the dice. Greg has no choice. He knows more than he's saying about Rachel's mysterious corpse. To add to his troubles, a school trustee plunges to his demise after a heated board meeting. Both deaths come with potentially lethal consequences. If he doesn't find answers, and soon, Greg Abimbola might be the third man on the autopsy table.
