Once Was Lost (A Marty Singer Mystery Book 6)

Retired DC homicide detective Marty Singer has spent his career—and his retirement—finding people. But Tommy Donlan and his son, Bobby, are on the run from their family, and Marty’s own family urges him to help the pair disappear—for good.

This isn’t just any family feud. Tommy is the nephew of Patrick Donlan, the leader of a tight-knit gang of criminals known for their violence, ruthlessness, and big scores. After getting pinched in a federal sting, Tommy was given a lethal ultimatum: testify against his uncle or do hard time. His choice made him a target—one that Witness Protection hasn’t been able to keep safe.

After Marty orchestrates Tommy’s disappearance, he figures his work is done. But when he discovers there’ll be blood on his hands if he doesn’t track Tommy down, he realizes the ordeal has only just begun.
