R. Holmes & Co. 

Raffles Holmes comes from impressive stock, with both larceny and detection in his blood in equal measure. He’s the son of the legendary detective Sherlock Holmes, and the grandson of gentleman criminal A. J. Raffles. No wonder he’s so conflicted between the desire to solve crimes and the urge to make sure the rich get their deserved comeuppance. Yet there is one ambition that is consistent in both sides of Holmes: making money. What’s the easiest way for him to make that cash? Selling the stories of his exploits, of course. And what tales they are! Holmes is as smooth an operator as his grandfather, and he finds himself the culprit of cases nearly as often as he is the detective. Whether burglarising for the greater good, fighting a desire to steal priceless jewellery, or playing the part of a bandit in order to save someone, Holmes is a rakish hero worthy of his name.
