Good old Stanley, always willing to do a favor. Stanley Hastings, the worst private detective in New York--maybe in the known universe--enters the big league. When asked to investigate Sergeant MacAullif's son-in-law, Stanley gets himself into trouble yet again. Doing favors can create a lot of problems. When Stanley takes on the case, he ends up doing one more favor than he expected: he unwittingly takes the blame for the questionable dealings of MacAullif's son-in-law. Now he must find a way out of this mess. Maybe he'll learn to be more cautious next time he's asked to do a favor.
