Empty Promises — James M. Jackson

Seamus McCree's first solo bodyguard assignment goes from bad to worse. His client disappears. His granddog finds a buried human bone. Police find a fresh human body.

His client is to testify in a Chicago money laundering trial. He's paranoid that with a price on his head, if the police know where he's staying, the information will leak. Seamus promised his business partner and lover, Abigail Hancock, that he'd keep the witness safe at the McCree family camp located deep in the Upper Peninsula of Michigan's woods.

Abigail is furious at his incompetence and their relationship flounders. Even his often-helpful son, Paddy, must put family safety ahead of helping his father. Seamus risks his own safety and freedom to turn amateur sleuth in hopes he can solve the crimes, fulfill his promise of protection, and win back Abigail. Wit and grit are on his side, but the clock is ticking . . . and the hit man is on his way.
