Murder by Precision

"I'd seen a gun like it. In the film Get Carter. A bad guy's gun. Two wide barrels hack-sawn to size along with the stock. A neat little homemade assassin's device you could slip down your pants and still walk down the street without limping. Both barrels looked me square in the eyes. I put my hands up. There was nothing in here to grab and Drago could see it."
Engineers Jake and Charlie believe the death of a colleague crushed in an industrial machine was no accident and talk each other into doing their own investigation. Involving maverick private detective Ron Selby seems like a good idea until they stumble on a drug distribution plant run by the director of a rival company. In too deep to back out of a bad situation, they use a combination of street-wisdom, Selby's expertise at digging out the truth and good luck to get to the bottom of a tense, darkly humorous and violent murder mystery.
