At the end of a long day, helping his father clean out an elderly aunt's home, the author spotted a pile of papers, old photographs and old notebooks that had somehow been overlooked. Piling them into a box, he loaded his car and left. Weeks later, sorting through the papers for a sister, he flipped open a stained school composition book. The words, 'The Adventure of...' caught his eye. He'd found a cache of Holmes cases, handwritten by Watson! Included are events spanning thirty years, from Holmes and Watson's days in Baker Street, through Holmes' supposed retirement. Surprising new details of Holmes's past are revealed during an adventure in Yorkshire, while a previously unrecorded trip to Tennessee in the United States in 1921 yields even more detail.
