Potshot, the fourth McMorrow mystery, delves deep into backwoods pot-growing and drug-dealing and the damage that comes when big, urban traffickers enter the picture. Jack alternates between the back-to-landers living communally on the outskirts of Florence, Maine, and confrontations with urban gangsters moving in on the product—and the people who Jack comes to know. Cronies at a county fair, an assassination attempt, and hostages are only a few of the challenges McMorrow has to face in this fast-paced addition to the McMorrow legacy. Library Journal says, "Along with snappy dialog that propels the story, Boyle presents an ensemble of likable characters. A sure thing for anyone who has enjoyed Robert Parker's Spenser."
