The Adventure of the Empty House (Unabridged‪)‬

This is the first of the Return of Sherlock Holmes stories in The Strand, which Doyle wrote after he discovered that the legions of his most famous creation's fans would let neither he nor the brilliant detective rest in peace. While still grieving over his great friend's death, Watson is stunned, relieved and joyful when Holmes suddenly appears and reveals that he has escaped an untimely end in that fatal struggle with his mortal enemy, Moriarty, at Reichenbach Falls. The criminal underworld suspects this, says Holmes, and Watson is drawn anew into Holmes's plot to deceive his enemies and foil a probable attempt upon his life.
