Boston Blackie - for young boys

If you want a fictional character to be a hero for little boys, try Boston Blackie. There is a full body of movies, television programs and radio shows about him, and all of them are watchable and listenable, even for adults. Yes, Blackie evidently had some sort of a shady past, but he is thoroughly reformed now, even though Inspector Faraday can't quite bring himself to believe it. Perhaps he does meddle a little too much in police affairs, but just think of how many cases they would not solve were it not for Blackie. His real name, by the way, is Horatio Black, but no one calls him that (except perhaps his mother). If you have little boys, I highly recommend your introducing them to Blackie.
