Book excerpt: Spree killers are probably the most notorious and infamous of all multiple murderers, yet these criminals confuse and fascinate us more than any other. Kids going on the rampage have captured the headlines recently, but William Cruse was a sixty-one-year-old retired librarian when one day he snapped, killing six including two policemen then attempting to kill another 24. Nor is it possible to understand why the perpetrators kill, many of whom were killed by the police at the end of their sprees, and therefore unanswerable to their crimes. Those who survived are usually certified insane famously when Brenda Spencer, who had killed two and wounded nine, was asked why she had done it, she simply replied: 'I dont like Monday.' Spree Killers provides the horribly fascinating sometimes enigmatic and inexplicable but always terrifyingly gripping stories of 45 spree killers, from the first recorded incident in 1913 through to the most recent high school and shopping mall slaughters.
