This has always been one of my favourite Abbott & Costello's, it's a short, frantic murder mystery with plenty of slapstick routines to keep us fans happy. I think the pace of it all and the average volume of Lou's voice probably puts some people off, but hey they can't really be fans then, can they?
A murder is committed in full view in a radio studio, Bud and Lou are on the case unasked as detectives before the "real" ones show up. There's an odd love interest with Patric Knowles and Louise Allbritton, because he comes into the story, departs gallantly saying he won't take charity from a woman, and after the murder also gets involved unasked. Favourite bits: Watt's a volt; Lou in the "clues closet", Lou crashing through glass windows leaving his fleeing shape and even making an impression on a wall - all complete with hat; Alexander 2222.
The marvellous wartime Universal studio atmosphere pervades with some beautiful shadowy lit shots at the radio station - in fact the A&C films I love best are all from this period, replete with the atmosphere the Universal technicians achieved seemingly so effortlessly then. To a fan: one of their best, to an unbeliever: don't trouble yourself or the fans.
