Investigating the murder of an old friend puts Charlie Chan (Sidney Toler) on the trail of a strangler, which leads to a cruise ship where he encounters more murders. Well, the title's accurate. It's kind of amusing that several people get knocked off before Charlie can solve the case. Doesn't exactly look good on a detective's résumé.
Toler's fine but his yellowface makeup seems especially exaggerated in this one. Maybe it's me but it just looks different. Always fun to see Victor Sen Yung as Jimmy Chan. Layne Tom, Jr. appears here but not as Charlie Chan, Jr. as in his previous appearances. This time he's "Number Seven Son" Willie. Cora Witherspoon is terrific comic relief as Susie Watson. Great supporting cast that includes Lionel Atwill and Leo G. Carroll, among other familiar faces.
This one's a remake of an earlier Charlie Chan film, Charlie Chan Carries On. Unfortunately that's one of the lost Warner Oland Chan films from the early '30s so I can't really compare this to that. But this one's good, with a solid cast and healthy doses of humor.
