Happy fifty-third birthday, Doctor. Welcome to the first day of your death. Dr. Frederick Starks, a New York psychoanalyst, has just received a mysterious, threatening letter. Now he finds himself in the middle of a horrific game designed by a man who calls himself Rumplestiltskin. The rules: in two weeks, Starks must guess his tormentor's identity. If Starks succeeds, he goes free. If he fails, Rumplestiltskin will destroy, one by one, fifty-two of Dr. Starks' loved ones—unless the good doctor agrees to kill himself.

In a blistering race against time, Starks is at the mercy of a psychopath's devious game of vengeance. He must find a way to stop the madman—before he himself is driven mad.
