Written by Tony Lee, with art by Dan Boultwood, these four books are said to chronicle the adventures of the Baker Street Irregulars, Holmes’ street urchin aides, during the period of the Great Hiatus when Holmes was believed dead after his fateful encounter with Professor James Moriarty at the Reichenbach Falls. Stories titles are: 'The Adventure Of The Missing Detective’, ‘The Adventure Of The Phantom Of Drury Lane’, ‘The Adventure Of The Charge Of The Old Brigade’ and ‘The Adventure Of The Family Reunion.’ In an effort to place the stories in Canonical context, Sherlockian expert Leslie S. Klinger was brought in as a consultant on the project.
