Book Description

An FBI agent’s affair with his informant ends in murder in this true crime account of the notorious case by the New York Times bestselling author. At twenty-seven years old, Susan Daniels Smith was a dirt poor, divorced mother of two living in rural Kentucky. She prayed for a Prince Charming to come to her rescue, and when good-looking FBI agent Mark Putnam entered her life, she thought those prayers had been answered. She was dead wrong. Their relationship began when Susan agreed to be Mark's paid informant in an investigation of her ex-husband's criminal friends. It quickly grew into an illicit affair that consumed their lives for nearly two years—until she became pregnant. Susan made demands, threatening to expose Mark in ways that ruined his career and marriage. On June 8, 1989, Mark took Susan for a drive into the hills to discuss her insistence on marriage. She was never heard from again. The FBI Killer recounts the bizarre events that forced Mark Putnam to confess to brutally killing his lover, then covering up his crime for more than a year.
