Dr. Clayton Solan's strange journey through the dark, tortuous places of his mind was of his own making - the result of a fantastic experiment pushed to the uttermost limits of control. It was a journey that was at one and the same time a self-inflicted penance and a desperate search for the solution to a life-and-death problem.
