O Estranho Caso do Dr. Rx

Patrick Knowles has had it with being a private detective in New York, and is about to head back to Boston. However, when the fifth acquitted murderer is found strangled with a note signed "Doctor Rx", attorney Samuel Hinds, whose clients all the victims were, and old buddy Police Chief Edmund McDonald rope him in on helping out with the case. Adding to the complications is Knowles' estranged wife, Anne Gwynne, who comes back into his life. She wants him retired from his dangerous profession and he agrees.

It's a decent comedy-mystery with most of the humor provided by Mantan Moreland as Knowles' manservant and Shemp Howard as McDonald's assistant. There is also Lionel Atwill as a "Doctor Fish" who always seems to be near at hand, Ray Corrigan in a gorilla suit to spice up proceedings, and a tiny but compelling role for a sultry Jan Wiley as a gangster's moll.

William Nigh, who had been directing movies for thirty years, helms the movie; he was one of the many A-list directors of silent movies who retreated to the Bs and never raised their heads after that. In the 1920s he had directed Marion Davies for Cosmopolitan and Lon Chaney for MGM. By 1932, he was directing B westerns, and spent the last fifteen years of his career at Monogram and PRC. This decent Universal programmer was as rarefied as he got in the sound era. He retired in 1948.
