Not since Jack the Ripper has there been such a gruesome crime scene. One look at the victim's apartment turned charnel house is enough for Milo Sturgis to summon his friend psychologist Dr Alex Delaware for insights into the mind behind such carnage. But even Alex Delaware's skills may be stymied when more slayings occur in the same ghastly fashion . . . with no apparent connection between them. The only clue left behind - a blank page bearing a question mark - seems to be both a menacing taunt and a cry for help from a killer baffled by his own lethal urges. This one will haunt Alex's waking life, and his darkest dreams, long after its end.
