This being the final entry in the Charlie Chan mystery series to be produced by 20th Century-Fox. Chan (Sidney Toler) finds himself summoned to a medieval-style castle built in the middle of the desert in the western U.S. It belongs to eccentric researcher Paul Manderlay (Douglass Dumbrille) and his wife Lucy (Lenita Lane) who happens to be a descendant of the infamous Borgias. They have a house full of guests, one or more of whom seems intent on killing them all.
This is an odd installment of the series, with a lot of comedy and an "old dark house" setting. The characters are all strange enough to hold one's interest, and Toler and Sen Yung's interplay is still fun. Fox decided to end the series with this one, stating a desire to cut back on film production during the war, but many feel it was also due to the Asian lead character, who, despite being Chinese-American, would still be resented by those with anti-Japanese sentiments due to the war. Toler himself would eventually buy the rights and take them to the poverty row Monogram company, where a new batch of Chan films started in 1944 with Charlie Chan in the Secret Service.
