Apprehension and growing menace pervade the diaries and letters of Dr Forrest's friends, recounting his disappearance. Hints of a harrowing conclusion are confirmed by his own chilling narrative. It won't spoil the plot to say that this is a modern version of the Faustian bargain complete with horror and perversion. If you don't believe in evil or the Devil, this book may change your mind. Read it alone, late at night, for best effect.
