Immoral Certainty (Butch Karp, #3)

New York. A world of mean streets, where a killer is operating with the "immortal certainty" that he or she will never have to pay for the snuffling out of human life. It's a world where Assistant D.A. Butch Karp and his beautiful colleague Marlene Ciampi must unravel three savage murders that they know of - and more that they suspect. Heading their list of suspects is a charming but vicious sociopath who turns out to be just the beginning of a twisted human chain that leads from a posh day-care center...to the Mafia...to a monstrous figure that child victims call "the Bogeyman." And just as three separate investigations are pulled into a single murderous knot, a kidnapping occurs that not only jeopardizes the case, but everything that Butch Karp holds dear.
