Detective Inspector Tom Thorne now knows that three murdered young women were a killer's mistakes—and that Alison was his triumph. And unless Thorne can enter the mind of a brilliant madman—a frighteningly elusive fiend who enjoys toying with the police as much as he savors his sick obsession—Alison Willetts will not be the last victim consigned forever to a hideous waking hell. Already an international bestseller, Mark Billingham's "Sleepyhead" is a chilling masterwork of crime fiction—a boldly original experiment in terror that will beget dark dreams and sleepless nights.
