Macdougal's Revenge

In Seattle, Mike MacDougal and his nurse, Melinda Morland, join a group of scientists on board Viking for a voyage to the Philippines.to investigate the work of Dr. Minerva Booger, brain surgeon, who claims she is close to transplanting human brains.
The NY Times has sent Esther MacDougal to interview Dr. Booger and her work among cannibals. She has disappeared.
Viking begins the voyage. Facing long empty evenings, the shipmates fill them with discussions on cannibalism, brain surgery, organ transplants, and the nagging question of religion versus science.
In the Philippines, close to her abandoned clinic, Dr. Booger's cannibal friends take Mike and Melinda captive.
Mike learns what has happened to his mother.
