The Chinese Ring is a 1947 American mystery film directed by William Beaudine and starring Roland Winters, Louise Currie and Warren Douglas.
It is a remake of the 1939 Monogram Pictures film Mr. Wong in Chinatown, with an identical story line and very little alterations of secondary characters.
The princess manages to give Chan’s butler Birmingham Brown (Mantan Moreland) an artifact - an ancient heirloom ring - before she is shot and killed by a poisoned arrow through the window.
Bill Davidson (Warren Douglas) with the SFPD comes to Chan, but his friend, the reporter Peggy Cartwright (Louise Currie), also arrives uninvited to the scene.
Chan continues his search for the money, visiting the banker (who reads and writes in fluent Chinese) in charge of handling the princess’ assets abroad, Armstrong (Byron Foulger).
