Description: Thomas Sullivan Magnum IV is a private investigator and lives in the guesthouse of a 200-acre beachfront estate called Robin's Nest, in Hawaii, at the invitation of its owner, Robin Masters. Ostensibly this is quid pro quo for Magnum's services based upon his expertise in security; the pilot and several early episodes suggest Magnum had done Masters a favor of some kind, possibly when Masters hired him for a case.
