From the curious clauses in a miser’s will, to a plea for help on a tiny scrap of paper, these six cases, from the early years of Holmes’s career in the 1880s, present a singular collection of mysteries for the world’s first consulting detective to resolve. What is the significance of the arrival in the post one morning of a cardboard packet of children’s bricks? Who is the man found dying in a deserted warehouse in London’s East End, and what is he doing there?

Sherlock Holmes is a Yorkshireman, born and brought up on the North York Moors, but he spent much of his life at 221B Baker Street in London. He is more than a character from Sir Arthur Conan Doyle's imagination. For many thousands of followers, he still lives in their minds through films, television, stage and radio plays, and written stories. Ever since Holmes first appeared in print, people have used the stories, together with knowledge of the culture of the late 19th and early 20th centuries, to speculate about his life. They wanted more than the 60 stories in the Canon.

With contributions from Stephen Fry, Mark Gatiss, Douglas Wilmer, and many more, this book was put together by fan site Sherlockology to help save Undershaw, the former home of Sir Arthur Conan Doyle.

Yig, known as the Serpent God, is older than humanity, and Yig’s reptilian children once ruled the Earth. Now they are stirring in their caves, walking the Earth in forms not quite human, slowly and patiently preparing their plans. Those who stumble on their secrets are in deadly danger...but only they can prevent the return of our darkest fears. 

Nick Hellyer faces the spy's ultimate dilemma. He is tasked to infiltrate a chemical weapons program and destroy it. But in the process, lives will be lost. His struggles with issues of complicity and guilt are set against a background of the guerrilla insurgency in Mozambique and the army plan to overthrow the Portuguese dictatorship in 1974. He succeeds in aligning himself with the coup plotters and participates in the virtually bloodless overthrow of the government. However, the tally of other deaths associated with him continues to pile up. 

Fusing together the two events are the recollections of Rita Krakowski, Holocaust survivor, condemned as a Nazi collaborator and fugitive from justice. Memories are branded into her soul like the number on her forearm, revelations with far-reaching international and financial implications. For private investigators Chas Broadhurst and René Marchal, what appears to be a straight-forward assignment rapidly becomes a deadly race against time to find the woman before it is too late and to expose a cover-up 70 years in the making. 

London. A snowy December, 1888. Sherlock Holmes, 34, is languishing and back on cocaine after a disastrous Ripper investigation. Watson can neither comfort nor rouse his friend - until a strangely encoded letter arrives from Paris. Mlle La Victoire, a beautiful French cabaret star, writes that her illegitimate son by an English lord has disappeared, and she has been attacked in the streets of Montmartre.

There is a persistent and incorrect idea, reinforced by countless film misrepresentations, that Sherlock Holmes and Dr. Watson were always staid and dull British chaps of middle years (or older), with Holmes a spry, cranky, and impatient eccentric, and Watson a white-haired and portly Boobus Brittanicus, a la Nigel Bruce. Students of the true and Canonical Sherlock Holmes know this to be a falsehood.

It is 1890, and in the days before Christmas, Sherlock Holmes and Dr. John Watson are visited at Baker Street by a new client. Eve Allerthorpe, eldest daughter of a grand but somewhat eccentric Yorkshire-based dynasty, is greatly distressed, as she believes she is being haunted by a demonic Christmas spirit. Her late mother told her terrifying tales of the sinister Black Thurrick, and Eve is sure that she has seen the creature from her bedroom window. What is more, she has begun to receive mysterious parcels of birch twigs, the Black Thurrick’s calling card.

Sherlock Holmes and Dr. Watson are no strangers to peculiar cases. Be it the dilemma of an Indian princess on the run, perfectly healthy people dropping dead as divine punishment, being challenged to a duel, a heartbroken and suicidal young man, a beautiful woman claiming to be Mrs. Holmes, a little boy who loves his dog, an old Scottish ghost that traditionally haunts husbands of pregnant women - there is very little they haven't seen (and solved). But, besides regular adventures, there are quite a few questions - Where was Holmes during the Great Hiatus?

The year 1894. The monstrous Hound of the Baskervilles has been dead for five years, along with its no less monstrous owner, the naturalist Jack Stapleton. Sir Henry Baskerville is living contentedly at Baskerville Hall with his new wife, Audrey, and their three-year-old son, Harry. Until, that is, Audrey’s lifeless body is found on the moors, drained of blood. It would appear some fiendish creature is once more at large on Dartmoor and has, like its predecessor, targeted the unfortunate Baskerville family. 

New adventures of the iconic sleuth, an icon of detective fiction. Readers, listeners, investigators, and artists have come across Sherlock Holmes and his mythical stories of crime and adventure for generations. Now comes an outstanding anthology of never-before-seen short fiction stories featuring the much-loved powers of deduction and unerring quest for the truth - however improbable it might first appear. The Book of Extraordinary New Sherlock Holmes Stories brings together some of the most renowned American and British crime and thriller authors of today.

In the year 1933, an elderly Dr. John Watson is looking back over his life and his time spent with his brilliant friend and master of deduction Sherlock Holmes. He writes in a letter to the listener that he has assembled a list of seven untold adventures that span from his and Sherlock's early years until the time of Sherlock's retirement. Watson explains that he wishes to leave, not only his family, but the public with a final compilation of adventures that he and Sherlock shared while he is still able. 

After surviving an attempt on his life in Paris, Sherlock Holmes returns to London, where the great detective is almost immediately enlisted by his brother to secure the safety of the delegates at a top-secret peace conference. With Europe a veritable powder keg in the years before World War I, Holmes understands any misstep on his part could prove fatal and possibly plunge the continent into war. However, after pledging to do his utmost for "King and Country", Holmes suddenly finds himself overwhelmed by an onslaught of cases.

Three linked crimes test Sherlock Holmes’ deductive powers, and his skepticism about the supernatural, to the limit.
