On a passenger liner heading for Dover, a man hides the valuable Borgia Pearl in a corner panel of his suitcase and then is called to the radio room for a message. Naomi Drake gets into his room and steals the pearl. In Dover, she hides it in a camera which she gives to an elderly minister to take through customs, as he is less likely to have his property searched. Later, she takes the camera to her boss, Giles Conover, but instead of the pearl, there's a taunting note from Sherlock Holmes who, disguised as the minister, has saved the pearl. Holmes, Dr. Watson and Inspector Lestrade deliver the pearl to the Royal Regent Museum where the museum curator shows them how a new electrical alarm system will protect it. Holmes, calling electricity "the high priest of false security," shows them how easy it would be to disarm the system, and while the alarm is off, Conover manages to steal the Borgia Pearl. He is caught not far from the museum, but he has already disposed of the pearl somewhere. As the press blames Holmes for the theft, Holmes investigates the murder of a man whose back was broken, with shattered porcelain figures scattered about the room. This may involve the re-emergence of the murderous Hoxton Creeper, a facially deformed man who was part of Conover's gang but has been thought dead. More murders with similar destruction occur and Holmes figures out that Conover, while being chased, had entered a ceramic shop and deposited the pearl of one of six newly made Napoleon busts which were then sold to customers. Conover and Drake have been tracking down the busts to find the pearl. Soon, Holmes tracks down the last recently bought Napoleon bust, but Conover also knows where it is. Can Holmes outwit him (and Drake, and the brutish Creeper) and save the pearl?
The seventh Universal present-day Holmes adventure is based loosely on the Doyle story, The Adventure of the Six Napoleons. The plot is interesting and the presence of Rondo Hatton as the Creeper gives added interest. The distortion of Hatton's face was caused by acromegaly. He had been a reporter but took small roles in several movies until this one made his Creeper character famous. He played a similar character in a few more movies before his death in 1946, actually getting top billing in THE BRUTE MAN. Hatton's presence (we don't actually see his face until the last ten minutes) helps detract from the weak performance of Miles Mander as Conover. Mander had a long career as a character actor, usually playing passive, milquetoast types, but he just doesn't cut it as an ambitious villain who is supposed to rival Moriarty in his crime career. For me, he brings the film's energy to a halt every time he appears. Evelyn Ankers, as Drake, is fine but underused. Basil Rathbone and Nigel Bruce (pictured) are rather like old friends by now, as are Dennis Hoey (Lestrade) and Mary Gordon (Mrs. Holmes). Some critics name this as one of the best in the series, mostly because it continued the trend away from wartime propaganda and toward Doyle-style mysteries, and also has a number of people in disguises, though it moves away from the creepy atmosphere of the previous film, THE SCARLET CLAW. I liked it but feel it's a notch below some of the others, though I must say I enjoy the fact that Holmes is responsible for the pearl's theft from the museum. In some of the films, any mistake he made like this would have been part of his plan, but this one is not. [DVD]
