The son of Sherlock Holmes (who also happens to also be the grandson of thief A. J. Raffles) decides to have his own adventures published. Upon selecting the man who will chronicle his life (much as Watson did for Holmes), we get the tale Raffles' astonishing origin, followed by an exciting series of adventures involving burglary, extortion, armed robbery, and more-with Raffles treading the fine line (and often slipping off) between good and evil, as the conflicting heritage of his sire and grandsire battle for dominance!
