It may come as a surprise to some that Donald Wandrei wrote more mysteries than all his horror, fantasy, and science fiction tales combined. D. H. Olson has assembled the first ever collection of Wandrei's ratiocinative detective I. V. Frost. Although a brilliant scientist, Frost prefers to solve most of cases through logical deduction in the traditions of Poe and Doyle. In this he is ably assisted by his beautiful and tough female assistant, Jean Moray.
