On the journey back from the Reichenbach Falls, Sherlock Holmes began writing his memoirs. The book was sent to a trusted friend and kept hidden until 2013 when it was accidentally found in an attic.
John Watson was clearing out his uncle's house, lugging down old boxes of musty clothes, books and Christmas decorations down the rickety ladder and throwing everything into the skip on the driveway.
The book fell out on top of his paint stained trainers. Something about the handwriting caught his attention. He's just read a book on graphology and thought it would be interesting to see what deductions he could make about the owner, a relative he imagined.
He shoved the book into his back pocket and continued with his dusty work. Never for a moment realising how his life was about to change.
