Cunning private eye Mr. Wong (Boris Karloff) is on the case once more after a beautiful Chinese princess (Lotus Long) is murdered in his San Francisco home. Before succumbing to a venomous dart, the princess scribbles "Captain J" -- but is this a hint to her killer's identity or another piece of the mysterious puzzle? As more victims are killed by the same dart gun, Wong tracks the clues to a certain Capt. Jaime (William Royle), and finds himself knee-deep in a check forgery scam.

Released: Aug 1, 1939
