I'm not an addict at all! I can stop whenever I want. Really I can.
Thirding or fourthing the Ann Rule love. Love her. And I, too, loved John Grisham's An Innocent Man--I enjoyed it more than most of his books, truth to tell.
Some other good true-crime books I've read recently: Seduced by Madness by Carol Pogash; Redbone: Murder, Malice, and Money in Atlanta by Ron Stodghill; and House of Secrets by Lowell Cauffiel.
I think my all-time favorite true-crime books are The Devil in the White City by Erik Larson; In Cold Blood by Truman Capote; and Midnight in the Garden of Good and Evil by John Berendt.
