The Chinese Ring is a 1947 American film directed by William Beaudine. The film is also known as Charlie Chan in the Chinese Ring (American poster title) and The Red Hornet. This is the first to feature Roland Winters as Charlie Chan. 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. Script writer W. Scott Darling reworked the plot line of Murder at Midnight (1931) for both later films. Charlie Chan (Roland Winters) is a private investigator living in San Francisco. One day a Chinese princess comes to visit him in his home. She has just arrived from the East by boat. 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. She leaves a note behind, with the name ”Captain K”. Chan calls for the police to investigate this murder. 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. By examining the ring, it turns out the princess’ name was Mei Ling (Barbara Jean Wong). She arrived in San Francisco weeks earlier with two men, Captain Kong (Philip Ahn) and Captain Kelso (Thayer Roberts), to try and acquire fighter planes to fight off an enemy back home. For this purpose she had brought a substantial amount of money, $1,000,000, with her on the journey. A search for the money ensues, but it soon turns out there are more people looking for the lost money. Peggy helps out in the hunt, and she meets the princess’ maid, Lillie Mae (Chabing), and a deaf-mute boy living in the princess apartment. When Chan comes to talk to the maid, he finds her murdered in the apartment, and the deaf-mute boy manages to tell him that a man came to visit the apartment shortly before the maid was found dead.
