In the early to mid-60s, I read a hardcover library book that I guess was published either late 50s or early 60s.  It was about a boy, I think his name was Charlie. He lived in a town where an old streetcar had been turned into a restaurant, so you could eat your meal while riding around the town.  And somehow he got mixed up with some incompetent burglars, who couldn’t get the slang term for “gun” right; instead of saying “gat,” they would mangle it somehow. I’m pretty sure Charlie had a large dog.
