Nick Carter, Master Detective (film)

Nick Carter, Master Detective is a 1939 film starring Walter Pidgeon in the title role based original stories created for the screen featuring the character from the long-running literary series. In the heightened tensions prior to World War II, Hollywood developed many films in the spy film genres such as "Nick Carter, Master Detective". In this film, Carter investigates espionage at an aircraft factory.
Pidgeon and Donald Meek went on to reprise their roles in two sequels, "Phantom Raiders" (1940) and "Sky Murder" (1941). 
Plot.
Detective Nick Carter boards an airliner with John Keller, the inventor of a revolutionary new aircraft at the Radex Aviation Company. The pilot makes an unscheduled landing so that his confederates can try to steal Keller's plans, but Carter holds them off, and stewardess Lou Farnsby manages to fly them to safety. Carter, posing as "Robert Chalmers", the new assistant to Hiram Streeter, the boss of the California factory, has Lou reassigned to the infirmary.
During his investigation, Carter receives the unwanted help of his companion, Bartholomew. His friend fancies himself an amateur sleuth.
A test flight of the new aircraft ends in disaster; the wings are ripped off during a high-speed dive, and the test pilot is killed. It is found that bolts attaching the wings were cut. Later, Carter finds Keller's body in a running car in a closed garage. Carter suspects Keller was strangled, and the scene staged to look like a suicide.
Finally, Carter notices that each time a part of the blueprints goes missing, a worker has a serious accident and is sent home by company doctor, Dr. Frankton. He surmises that sections of the plans have been photographed, with photos hidden under bandages. He goes to apprehend the Frankton. Unable to leave the factory in time, he has the unsuspecting Lou escort a "patient" home. When Carter arrives, Frankton tells him that Lou will be killed unless the doctor shows up at a prearranged rendezvous soon.
Carter lets him leave, but secretly has the roof of Frankton's car painted with a white cross. This enables Carter to track the doctor in an aircraft to a section of the Los Angeles docks. Frankton, his associates, the complete plans and Lou race to a waiting ship. Carter engages in a firefight with the crew using a Tommy gun borrowed from the police.
Although his aircraft is shot down, Carter prevents their getaway. At the instigation of Bartholomew, a harbor patrol gunboat arrives and the villains are forced to surrender.

Reception.

Film reviewer Frank S. Nugent in his review of "Nick Carter, Master Detective", wrote in "The New York Times", "No, this isn't Nick Carter as we remember him, but it's an amusing fiction for all that, with enough action to compensate for the arch unoriginality of the plot and with pleasantly casual performances all around. ... They [Pidgeon and Meek] make a gay crime-solving combination".
Reviewer Tom Milne in "Time Out" (magazine), more recently stated, "Tourneur's second film in Hollywood, it's briskly and competently done, but the best thing about it is Donald Meek's performance as Bartholomew, the Bee Man, a mousy little apiculturist who fancies himself as a private eye."
