The Seven-Per-Cent Solution (1986)

First published in 1974, this is a 1986 paperback edition of Nicholas Meyer's bestselling Holmes novel, The Seven-Per-Cent Solution. Over two million copies in print then, and it's still in print today.

SHERLOCK HOLMES AND SIGMUND FREUD
TOGETHER AGAIN FOR THE FIRST TIME!

First discovered and then painstakingly edited and annotated by Nicholas Meyer, The Seven-Per-Cent Solution related the astounding and previously unknown collaboration of Sigmund Freud with Sherlock Holmes, as recorded by Holmes's friend and chronicler, Dr. John H. Watson. In addition to its breathtaking account of their collaboration on a case of diabolic conspiracy in which the lives of millions hang in the balance, it reveals such matters as the real identity of the heinous professor Moriarty, the dark secret shared by Sherlock and his brother Mycroft Holmes, and the detective's true whereabouts during the Great Hiatus, when the world believed him to be dead.

The MX Book of New Sherlock Holmes Stories, Part IV: 2016 Annual (2016)

The fourth book in what will now be an ongoing collection of new Holmes stories published by MX to help preserve the former home of Sir Arthur Conan Doyle. Release date is May 22.

In 2015, The MX Book of New Sherlock Holmes Stories burst upon the scene, featuring over sixty new traditional Sherlock Holmes adventures, all set within the correct time period, and written by many of today's leading Sherlockian authors from around the world. This first anthology, spread over three huge volumes, was the largest collection of its kind ever assembled in one place. Response was immediately and overwhelmingly positive, and there were soon calls for additional volumes. The result is this new collection, the next in an ongoing series, featuring twenty-two more Holmes investigations. 

Since his first appearance in print in 1887, the popularity of Sherlock Holmes has only increased. Although originally chronicled in just sixty exploits, the number of additional Holmes tales discovered since then is literally in the tens of thousands. Along with those original narratives published by Dr. Watson's first literary agent, Sir Arthur Conan Doyle, countless other people have managed to find their way to Watson's Tin Dispatch Box in order to reveal more exciting cases featuring the Great Detective. These accounts stretch from one of Holmes's earliest cases, later recounted to Watson as they sit by the fire in the Baker Street sitting room, to an adventure just before Holmes's retirement that affects both the ancient history and the very future of England. These and all the other excellent tales contained in this volume represent some of the finest new Holmesian storytelling to be found, and honor the man described by Watson as "the best and wisest . . . whom I have ever known." 

All royalties from this collection are being donated by the writers for the benefit of the preservation of Undershaw, one of the former homes of Sir Arthur Conan Doyle. The "Part IV: 2016 Annual" features contributions by: Derrick Belanger, Deanna Baran, Daniel D. Victor, Mark Mower, Craig Janacek, Jayantika Ganguly, Denis O. Smith, Matthew Booth, J.R. Campbell, Bonnie MacBird, Arthur Hall, Bob Byrne, Andrew Lane, Roger Johnson, Hugh Ashton, David Stuart Davies, Vincent W. Wright, Daniel McGachey, Nicholas Utechin, Jeremy Holstein, David Marcum, and Marcia Wilson, as well as a poem by Andrea Mantin Levy, and forewords by David Marcum, Steven Rothman, Richard Doyle, Steve Emecz, and Melissa Farnham.
