This very good Charlie Chan mystery was made at 20th Century Fox. At this time the series still had the backing of a major studio and so the production values, acting, script, camera work, etc. were of good quality. Later, when Fox dropped the series and it found a home at Monogram, the Chan films got pretty bad with the look of cheapness in abundance. But, this film had some very good actors, such as Ricardo Cortez, Robert Lowery, and the always funny Slim Summerville supporting Sidney Toler as Chan. There seemed to be just the right amount of comic relief to keep the story moving at a good pace. Later Chan entries would go overboard with comedy with Mantan Moreland and company trying to avert the viewers from realizing what lame plots and bad acting they were watching. Of course, as in all Chan mysteries, there is no shortage of suspects in the case of a murder that is committed on a thoroughly unlikeable woman who seemed to go out of her way to alienate everyone. With several characters having a motive to kill the woman, Chan must sort out the clues and unmask the killer while continually being harassed by an inept (but very funny) sheriff, portrayed by Summerville. Victor Sen-Yung, as number two son, helps out when it counts while enduring the usual number of affectionate insults from his detective father. All in all, this movie is great fun.
