Suddenly Gone: The Terrifying True Story of a Serial Killer's Grisly Kidnapping-Murders of Three Young Women

By Dan Mitrione. Per Google Books, "Dan Mitrione, a former investigator with the Federal Bureau of Investigation, is the author of Suddenly Gone: The Kansas Murders of Serial Killer Richard Grissom. The book chronicles the true story of the hunt for Grissom, a terrifying killer who tortured and murdered four young women in Wichita and Kansas City, Kans. in 1989," so evidently this one had a different subtitle in hardcover.  This paperback is a bit frumpy -- edgewear, cracked and leaning spine -- but is a bit harder to find than you'd think.
