Edgar Wallace 
Angel Esquire 

Excerpt: "Angel Esquire, of Scotland Yard, has his hands full in helping Jimmy Stannard, as he is known to the criminal element of London, solve the puzzle of the great safe which held the fortune of Old Reale who had placed it there, and who had taken the precaution to hide the combination in a bit of doggerel verse that served as a cryptogram. When Old Reale’s Will was read it was found that four people might benefit by it. Two of them, known as members of the famous "Borough Lots" gang would stop at nothing to gain possession of the fortune. Jimmy and his friend are pitted against them in a story that constitutes the finest entertainment for the person liking excitement, love and mystery combined."
