Synopsis for "The Night Crawler"

Nosy neighbor Ima Snoop finds Captain Marvel, Jr.'s Diary in Freddy Freeman's boarding-house room, and gossips this info around town. Unscrupulous publishers Slink & Slouch hear about it, and try to buy the Diary from Freddy, who pretends to not have it. They then hire a cat burglar, the Night Crawler, to steal the book, which he does, knocking Freddy unconscious in the process. Freddy recovers and starts searching for the stolen book, arriving quickly in the neighborhood of the publishers's office. The publishers try to cheat the burglar out of the agreed-upon fee, and there's a scuffle, in which both of them get knocked out with a blackjack and some shots get fired. The noise draws Marvel Junior to the scene. Night Crawler flees to the roof of the building, where he finds the world's most conveniently-placed drum of hot tar, on top of a gas-fired burner, right by the edge of the roof, and dumps it over the roof's edge onto Marvel Junior. CMJ gets the tar off himself by transforming to Freddy, falling a few stories, then transforming back, then resumes the pursuit. Night Crawler distracts Marvel Junior by throwing the Diary into the gas-fired burner, and while the superhero is distracted, he jumps over the other edge of the roof, and tries to do a flagpole-swing to another roof, but the pole breaks off and he falls to his death.
