What is greatness without madness? Criminal profiler Matthew Moore wouldn't know. To him there's no difference. Cursed with the perfection of a sharp mind but a heart void of feelings, finding an outlet for his unique abilities proves to be difficult until he discovers the wonders of psychiatry-that is, the joy of driving a number of his psychiatrists to suicide. Soon growing bored of that, however, he yearns for a new challenge: the chance to face off against someone with the same abilities and savage desires that he harbours. In this regard, his next target, Anthony Gallo turns out to be a dream come true. A renowned psychiatrist, Anthony secretly shares Matthew's abilities and his terrifying lack of empathy, which he uses to drive his patients to self-destruction, just as Matthew does with those who attempt to treat him. Recognizing each other in a way that only two people cursed with the same "gifts" can, the two predators are soon locked into a lethal battle of wits that is equal parts bloodlust and adoration. How deeply will their lives and carnal impulses mesh before one of them emerges victorious, and if that happens, what will be left for the last man standing?
