Following quickly on the gumshoes of Groucho Marx, Private Eye, this third installment in the mystery series starring Groucho Marx and scriptwriter Frank Denby ups the ante by killing off a German director on the set of a Sherlock Holmes movie. The star of the film, one Miles Ravenshaw, calls a press conference and challenges Groucho to a duel of wits and discovery, saying “I fully suspect, old man, that once that baggy pants mountebank learns that Miles Ravenshaw is on the case, he won’t even dare to compete.” After that, not investigating the case is out of the question, not to mention checking with his tailor.
We visit a Mexican café owned by a Swede, (and the food is just the way it you would predict), hob nob with studio heads, PR flacks, starlets and Nazis. To say nothing of the dog. Groucho is peddling a script for a movie called “Cinderella on Wheels,” Frank’s wife Jane plays an important part, there are more interesting characters than ever, and the complex plot is the most satisfying yet.
