To make the Raffles books even better - not only are they basically Holmes and Watson but criminals; Hornung was ACD's brother-in-law, and Raffles and Bunny were pretty much an intentional Holmes and Watson parody, complete with OTT slashiness that might actually have been intentional.
Be warned for some A Product Of It's Time casual racism in one or two of the stories, though."
