The memoirs of Sherlock Holmes ([New] edition)

Sherlock Holmes is back on the case in this collection of short stories, in which we learn about Holmes' early days as a sleuth, encounter a seemingly murderous widow, and meet the great detective's brother, Mycroft, for the first time. And, in 'The Final Problem', Holmes comes face-to-face with his nemesis, Professor Moriarty, in a battle of wits that could kill them both.
