For many years it has been widely accepted that the complete canon of Sherlock Holmes's adventures by Sir Arthur Conan Doyle consisted of fifty-six stories and four novels. But there have also been persistent rumors of a number of other items that Conan Doyle wrote about his world-famous detective and which, for one reason or another, have never been included in the collected works. Now these missing items, including stories, plays and poems, have at last been unearthed from obscurity and are published in this volume to provide the final remaining authentic accounts of the great sleuth.
