Number 5 in W. Glenn Duncan’s amusing Rafferty series is Cannon’s Mouth. Hard-boiled detection on the lighter side of the scale (though plenty of dark stuff happens).

Rafferty, as you may recall, is a Dallas private eye. He’s surveilling a delivery man suspected of pilferage on a hot Dallas day, when he steps into a little park to spy from the shade. A small, pudgy man comes up to him and starts talking as if he knows him. Talks about murdering his business partner, who is ruining the business. Rafferty is so hot and impatient that he barely pays attention to the man. But afterwards he does his civic duty by alerting his friends on the police force, providing all the details he can remember. They’re not much impressed.

Until the named target shows up dead, the night before the “contract” had specified. Worse than that, Rafferty is the one who finds the body. Now he needs to do some quick dancing with suspicious cops, including the leader of a drug task force who’s taken an unexplained interest in the proceedings.

Even when he’s released, Rafferty’s problems aren’t over. Somebody is calling him to demand the money they “earned.” And they’re not above throwing a bomb or two to show they’re serious.

Cannon’s Mouth leans a little too heavily on coincidence in its plotting to please me. And, as always, Rafferty isn’t as funny as he thinks he is. Still, the book was likeable and diverting, and I can recommend it as light reading – the kind of book you’d enjoy taking to the beach this summer. Plus, it’s a couple decades old, so it doesn’t preach at you.
