A stilted, obvious mystery, easy to read and full of unlikely actions, follows the Mulford family who are returning from Hong Kong where Mr. Mulford has been posted with the Eastern Tea Company. On the day they sail, the story of a ruby from a buddha's forehead breaks in the papers. Out at sea, young Ted Mulford and Fred find the ruby in Ted's shoe. They begin to suspect Mr. Wu, a friend of their houseboy's, but in San Francisco Mr. Wu turns out to be a detective who explains every thing to them in a climactic last chapter exposing the real culprits. Cope and robbers, orientally styled.
