"Brilliant jazz pianist Brent ... is plagued by fragmented visions of the past, and has resigned himself to a life of quiet desolation. That is, until the night he meets wealthy and eccentric jazz fan Leonard Fry. In the days that follow, Leonard makes Brent a devilish deal, proposing a bizarre experiment in which Brent will play a vital part. The deal provides an opportunity ... for the two men to move beyond the one terrifying frontier from which neither of them can be sure they'll ever return: the borders of their own sanity."--Back cover.
