A convicted murderer (Marc Lawrence) escapes and vows revenge on Charlie Chan (Sidney Toler). He receives help from an unscrupulous doctor who lures Charlie to his wax museum for a radio show on criminal cases. I realize that sentence doesn't make a lot of sense but trust me it works out okay. "Number Two Son" Jimmy (Victor Sen Yung) is especially high-strung in this one. Chan series vet C. Henry Gordon plays humorously-named villain Dr. Cream. Joan Valerie and Marguerite Chapman provide the pretty. Spooky wax museum backdrop is a plus. This one's got lots of suspects and atmosphere to spare. There are also quite a few implausibilities so be prepared to suspend disbelief more than usual. Still, it's good fun.
