Some doctoral candidate is doubtless hard at work as you read this, trying to explain why and how the serial killer suddenly became every thriller writer's favorite subject. Meanwhile, the irrepressible Tami Hoag shows us in her latest sure-to-be-a-bestseller how the theme should be handled--with sensitivity, wit, and enough energy to heat a small city. A monster known as the Cremator is killing prostitutes in Minneapolis parks and setting their bodies on fire. When one of his victims turns out to be the daughter of a local billionaire, and a homeless teenager claims to have witnessed the burning, it brings together former FBI agent Kate Conlan (now working as a victim-witness advocate) and the Bureau's top serial-killer profiler, John Quinn. Conlan and Quinn share a painful personal history; now they have to work together against a very smart lunatic who seems to be able to read their minds. Although none of this is actually groundbreaking material, Hoag leaps into her story as if she were the very first writer to have thought of it. Guess what? Her innocence and verve are contagious. We throw skepticism to the winds and gladly go along for the thrilling and romantic ride, just as we did in other Hoag hits such as Cry Wolf, Dark Paradise, Guilty As Sin, Lucky's Lady, Magic, Night Sins, Still Waters, and A Thin Dark Line--all available in paperback. --Dick Adler
