This is a straightforward detective movie with all the quaintness of the era. The story isn’t the kind that the audience can solve as they watch, but its adventure is fun to watch as the characters go through it. It is only a slightly more interesting story than its contemporary peers, but with a runtime of only about an hour it doesn’t overstay its welcome.

Closest comparison: It’s like The Riverside Murder crossed with Tintin.

Setting: Crime
Plot: Detective
Tone: Adventure
