Although the illustrious career of Sherlock Holmes has been documented in innumerable stories over the decades, some accounts have remained classified due to their extremely sensitive nature…. Now, these cases are available to listeners in the collection The Undiscovered Archives of Sherlock Holmes.

In The Adventure of the Jeweled Falcon, Holmes tracks down an ancient priceless statue, but others are looking for it too. In The Case of the Violin Savant, using clues found in the sophisticated musical compositions of a celebrated but mute nine-year-old violin savant, Holmes and Watson attempt to discover where and why the boy and his parents vanished. In The Adventure of Stonehenge in London, Holmes and Watson stumble upon a strange structure on the roof of a mansion in London, and somehow it relates to the missing eighth Earl of Rendlesham. 

Did you ever wonder where Sherlock Holmes found the Persian slipper he keeps his shag tobacco in? Had Holmes and Watson ever met before that day at St. Barts? Did Holmes really believe in curses when he said he did? Dr. John Watson reveals the answers to these questions in The Persian Slipper and Other Stories, along with cases involving the putative Naval Man, a night spent at a gentlemen’s club, Holmes’ second marriage proposal, a movable tree, and a surprising wedding ending.

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?

When Mrs. Hudson asks Holmes and Watson to find a missing girl, neither men expected what they would find. Along with Lestrade, they are plunged into a case of abduction and murder. As they race from Marylebone, to Finchley, to Wapping, and back again, time is running out for them to solve the case without further casualties. With two of their own under threat, the pressure is mounting to catch and stop the group known as "Hellfire Heirs".
