Elmore Leonard: 52 Pickup (USA 2002)
From the Publisher:
Detroit businessman Harry Mitchell had had only one affair in his twenty-two years of happy matrimony. Unfortunately someone caught his indiscretion on film and now wants Harry to fork over one hundred grand to keep his infidelity a secret. And if Harry doesn't pay up, the blackmailer and his associates plan to press a lot harder -- up to and including homicide, if necessary. But the psychos picked the wrong pigeon for their murderous scam. Because Harry Mitchell doesn't get mad... he gets even.
