Plot
A wealthy gem-collector, Brandon Edwards, gains possession of the largest star sapphire in the world, the 'Eye of the Daughter of the Moon', after it has been stolen in China. Edwards, at a party in his home, confides to Mr. Wong that his life is in danger. During a game of Charades (called "Indications" by Mrs. Edwards), Edwards is mysteriously shot dead and the gem disappears. Unbeknownst to Wong, the jewel is in possession of Edwards' maid, Drina, who intends to return it to China, but she too is murdered, and the gem is taken again. After one more murder—the suspect list is dwindling—Wong exposes the killer, turns him over to Police Inspector Street, and orders his manservant Willy to return the gem to China.
