Gilbert Pinfold is a reclusive Catholic novelist suffering from acute inertia. In an attempt to keep insomnia at bay he has been imbibing an unappetizing cocktail of bromide, chloral, and creme de menthe. He books a passage on the SS Caliban, and as it cruises towards Ceylon, he slips into madness. Almost as soon as the gangplank lifts, Pinfold hears sounds coming out of the ceiling of his cabin: wild jazz bands, barking dogs, and loud revival meetings. He is convinced that an erratic public-address system is letting him hear everything that goes on aboard ship....until instead of just sounds, he hears voices. But not just any voices. These voices are talking, in the most frighteningly intimate way, about him!
