The Big Casino

Dugan, Travis Dugan, is an un-ambitious P.I. summoned to the island by a sultry representative of the Rigney family, the candy conglomerate that owns the island, to investigate the disappearance of the family's heir apparent. Our reluctant hero finds himself mixed up in a search for a fabulous sunken Chinese treasure, pursuing and pursued by black-market arms smugglers, the British Secret Service, and murder.
