The Deadly Pearls

A small Hawaiian island has but three inhabitants—a malicious retired colonel, an eccentric old woman and the beautiful girlfriend of a mobster. All are resentful of the intrusion of private investigator Keith Spencer, posing as a novelist, whose task is to find a string of pearls coated with radium that will bring death to the wearer. Spencer narrowly escapes death at the hands of all three, in each case a seeming accident, and determines he'll only find the owner of the pearls in a bridge game in which the stakes are very high indeed.

A tiny Hawaiian island is home to just three people—a mean former army colonel, a strange old lady, and a gangster's pretty girlfriend. They all hate that private detective Keith Spencer has come to their island, pretending to be a writer. His job is to track down a necklace of pearls covered with deadly radium that will kill whoever wears it. Spencer barely survives when all three residents try to kill him in ways that look like accidents. He figures out that the only way to find who owns the dangerous pearls is to play a card game where everyone risks everything.
