I shall never understand why Leopold & Loeb didn't have as many hits as Meltz & Ernest.
They got caught.

I finished the book by Simon Baatz, "For the Thrill of It, Leopold, Loeb and the murder that Shocked Chicago". It is, I think, the best researched and most readable book on the subject. (considering there's really only one or two non-fiction on the subject, that isn't hard - but this was good) I've read other books, including Leopold's "Life plus 99 Years" and never learned as much about what really happened in court etc. If you have any interest in the case at all, it's a very good read. It does get into lots of detail about the psychiatrists' testimony and the back and forth between Clarence Darrow and Robert Crowe, the sort of thing I find quite interesting.
