The Nitwits are of course Wheeler&Woolsey and in this film they own a cigar stand in the building where music publisher Hale Hamilton has an office. Hamilton's got a secretary played by Betty Grable that Bert is stuck on. Hamilton's married to Evelyn Brent, but never lets that stand in the way of a little nookie.
Anyway, a notorious criminal called the Black Widow is known for sending out letters of extortion demanding money or the victim would be killed. Hamilton decides not to give in and does wind up dead as a result.
Unlike Abbott&Costello's Who Done It which has a lot of the same plot premise, The Nitwits is better edited and the perpetrator doesn't come out of nowhere as in Bud&Lou's film. Unfortunately due to one of the gags which involves Woolsey inventing a chair in which a charge of electricity passes through you so you blurt the truth out, we learn a little prematurely in my opinion who the culprit is.
Anyway because Betty is a prime suspect, Wheeler&Woolsey get themselves involved in the investigation. They prove as much help to the cops as Abbott&Costello did, but like them they do stumble on to the perpetrator.
One reason this film is not revived too often is the climax also involves a bunch of black people being allowed by one of their peers who works as a janitor to use the basement for a quiet crap game. Their fright reactions in the climatic chase of the culprit plays into a lot of racial stereotyping.
Anyway I did like Woolsey's Rube Goldberg contraption as a gag. Maybe they could use a real one of those at Guantanamo.
