When the elderly woman sponsoring a treasure hunt is murdered on board her docked ship, Charlie Chan must deal with a treasure map in four pieces, the ghost of a hanged pirate, a talking parrot, a recalcitrant sea captain and several suspicious passengers - and a second murder.

Charlie Chan's investigation of a blackmail-induced suicide as a case of murder leads him into a world of magick and mysticism peopled with a stage magician, a phoney spiritualist, and a for-real mind reader.

A wax museum run by a demented doctor contains statues of such crime figures as Jack the Ripper and Bluebeard. In addition to making wax statues the doctor performs plastic surgery. It is here that an arch fiend takes refuge.

Of all the Fritz Lang films I have seen, this may be the one that I was least enamored with. Gary Cooper seems miscast as an atomic scientist (Prof. Alvah Jesper), who is sent to Europe by the OSS to rescue other scientists who are being forced to cooperate with the Nazi atom bomb project. During his mission, he becomes involved with the Italian resistance, falling for plucky Gina (Lilli Palmer). I've read that Lang originally shot this film emphasizing the dangers of atomic power, but Warner re-edited and it fails to have any direction. It still shows a few Lang-esque moments, but this is only recommended for his most devout following as it really lacks any punch... or his signature panache.
