For all we know, or think we know, about Sherlock Holmes and Doctor Watson, what we don’t know is far, far greater. In the duo’s first case, A Study in Scarlet, we learn that Holmes and Watson met on January 1st, 1881, and subsequently moved into an apartment together at 221b Baker Street. Their first case officially began on March 4th of that year, and it is argued that “The Adventure of the Resident Patient” possibly took place in October of 1881, depending on which version of the story you read. But what happened during the rest of 1881? Or all of 1882?

Set in late January and early February of 1891, during the time that Professor Moriarty declares in The Final Problem that Holmes had "incommoded" his plans, Holmes and Watson are visited by two charwomen and retained to clear the name of a drunkard lighthouse keeper who has been arrested and charged with the murder of a German man in Tynemouth, England.

It's Christmas eve at 221B Baker Street. On the stroke of midnight, a delivery arrives addressed to Sherlock Holmes. The message is a cryptogram which reveals itself to be so obtuse that it has the famous consulting detective baffled. Holmes becomes so obsessed with revealing the secret of the cypher that Watson fears for his well-being in refusing to eat or sleep. Holmes can only deduce that time is of the essence, and that a means of deciphering must be discovered which has never before been employed. Watson wonders what new adventure will emerge, should the puzzle be unraveled. 

1896. A new client at Baker Street claims he’s being threatened via the new art of the moving image. Eadweard Muybridge, pioneer of motion picture projection, believes his life is in danger. Twice he has been almost run down in the street by the same mysterious carriage, and moreover, disturbing alterations have been made to his lecture slides. These are closely guarded, yet just before each lecture an unknown hand has defaced images depicting Muybridge himself, which he has discovered, to his horror, only as he projects them to his audience.

It is the autumn of 1880, and Dr. John Watson has just returned from Afghanistan. Badly injured and desperate to forget a nightmarish expedition that left him doubting his sanity, Watson is close to destitution when he meets the extraordinary Sherlock Holmes, who is investigating a series of deaths in the Shadwell district of London. Several bodies have been found, the victims appearing to have starved to death over the course of several weeks, and yet they were reported alive and well mere days before.
