Protecting an actor takes Drum into the seedy underworld of psychedelia.

Terminal illness and regret go hand-in-hand. Two months ago, Amos Littlejohn was in the prime of life, and had plenty of energy to be enraged when his pregnant daughter was abandoned by her husband, matinee idol Ahmed Shiraz. Now stricken with leukemia, Littlejohn is near death, and beginning to regret taking out a contract on the actor's life. He hires international private eye Chester Drum to call off the hit and protect Shiraz until his life is safe. On his first night on the job, Drum's partner takes a shotgun blast meant for the actor. Wanting nothing more than to wring Shiraz's neck, Drum follows him to Europe, where he must contend with assassins, beatniks, and the powerful effects of an experimental drug called LSD.
