Hal is a mild-mannered IRS bureaucrat who suspects that his wife is cheating with her younger, more virile coworker. At a drunken dinner party, Hal volunteers to fly to Belize in search of Susan's employer, T.--the protagonist of Lydia Millet's novel How the Dead Dream--who has vanished in a tropical jungle, initiating a darkly humorous descent into strange and unpredictable terrain.
