Sherlock Holmes & the Case of the Twain Papers (2014)

Roger Riccard's follow-up to Sherlock Holmes and the Case of the Poisoned Lilly finds the great detective working for a very famous writer (and I don't mean Conan Doyle).

"It may not seem much to you, Mr.Holmes. In fact, it may better gather the sympathies of Dr. Watson here. But, the truth of the matter is, someone has stolen my life." 

In the silence that followed this extraordinary statement, Clemens pulled out his cigar case and quietly asked, "Do y'all mind if I smoke, gentlemen?" 

So begins a case where visiting American author, Samuel Clemens (better known as Mark Twain), has come to Sherlock Holmes for assistance. Holmes and Watson set out to track down the thief among a myriad of guests staying at the famous Langham Hotel. 

Suspects abound, yet another pressing question arises for Dr. Watson. Will one of them, a woman from his past, steal his heart?

The Adventure of the New York Ripper (2013)

Holmes and Watson are on the trail of Jack The Ripper in 1893 New York.

Terror is walking the streets of 1893 New York City at night, taking the lives of women in a horrible fashion reminiscent of the heinous murders of Jack the Ripper in London five years earlier. A copycat “Jack the Ripper”? Or is it possible that the infamous killer himself, never captured by the London police, has made his way to the streets of New York City? 

In The Adventure of The New York Ripper, we are, in addition to an outstanding mystery, presented with a history of the horrific Jack the Ripper crimes and with a brand-new theory regarding the commission of those terrible murders. A theory arising out of data of the crimes themselves and from the deductive powers of the one and only Sherlock Holmes.

The Pandora Plague (1981)

The Pandora Plague by Lee A. Matthias was first published as a mass market paperback from Leisure Books (below). Because of financial problems, the publisher only gave it a limited release. It later appeared as a trade paperback from Unicorn Press cut down by 8000 words. The author self-published a revised and expanded 3rd edition in 2009.

PUZZLING EVIDENCE 

The theft of a seemingly innocuous pocket watch, and the appearance of a small and mystifying heavy box, began Sherlock Holmes' most challenging case. In an attempt to open the box, Holmes requested the presence of master magician Harry Houdini. 

Soon, a series of puzzling events accelerated into a crisis of shocking importance, and Holmes, Houdini and Dr. Watson were drawn into the evil machinations of a hideously sinister plot. 

Holmes' abilities were pushed beyond their limits, and a startling discovery by Madame Curie told the great detective that the world's fate rested in his hands!

A Study in Treason (2018)

The second book in a series by Leonard Goldberg featuring the daughter of Sherlock Holmes and Irene Adler.

A seemingly impossible mystery tests the keen mind and forensic skills of Joanna Blalock, the daughter of Sherlock Holmes and the heir to his unique talent for deduction, from USA Today bestselling author Leonard Goldberg. 

The following case has not previously been disclosed to the public due to the sensitive information on foreign affairs. All those involved were previously bound by the Official Secrets Act. With the passage of time and the onset of the Great War, these impediments have been removed and the story can now be safely told. 

When an executed original of a secret treaty between England and France, known as the French Treaty, is stolen from the country estate of Lord Halifax, Scotland Yard asks Joanna, Dr. John Watson, Jr., and Dr. John Watson, Sr. to use their detective skills to participate in the hunt for the missing treaty. As the government becomes more restless to find the missing document and traditional investigative means fail to turn up the culprit, Joanna is forced to devise a clever plan to trap the thief and recover the missing treaty. 

Told from the point of view of Dr. John Watson, Jr. in a style similar to the original Sherlock Holmes stories, A Study in Treason is based partly on facts in our world and partly on the facts left to us by Sir Arthur Conan Doyle. 

This cunning locked room mystery is sure to be enjoyed by fans of Sherlock Holmes.

The Execution of Sherlock Holmes (2008)

More Holmes stories by Donald Thomas.

Drugged, manacled, condemned to a dank cell in the depths of London's infamous Newgate prison, the world's greatest literary detective awaits execution by a vengeful crew of formidable enemies. Escape is impossible; death, a certainty. But not for Sherlock Holmes, who, in a stunning display of intellect and derring-do, will elude his hangman's noose and live to fiddle, spy and ratiocinate another day. 

Against tremendous odds Holmes will continue to defy his enemies in four more encounters, from cracking German intelligence codes, to going against Scotland Yard and the Crown in proving the innocence of a man condemned to death for the slaying of a pregnant serving girl, to an arsenic-wielding magician, and of course, to a battle of wits with the malevolent Moriarty. Everywhere in these five finely wrought tales, riddles and mystery hover in the air. But they are not beyond the grasp of the incomparable Sherlock Holmes.

The sixth collection of August Derleth's Solar Pons stories was released as the 4th paperback by Pinnacle Books in 1975. Contains a Foreword by Vincent Starrett.

Whatever your fancy in the polished old world of deductive detective cunning-- a mummified human hand conspiciously resting in an intarsia box, a haunted moonlit library, a tattered corpse caught up in a rapacious invincible curse-- Solar Pons will quickly capture your curiosity and leave you hungering for more. 

Soon you will find yourself a regular visitor at No. 7B Praed Street, eagerly peering into the mind of the contemplative Pons, slouched in the cozy cavern of his armchair. And as you faithfully follow the master about charming, chilling fin-de-ciecle London, discretely clutching and unclutching your hands between counter plots and climaxes, you know that you have found a lifelong companion-- the incomparable and brilliant Solar Pons, heir to the genius that was once uniquely Sherlock Holmes'.

The Giant Rat of Sumatra (1976)

Sherlock's greatest untold tale, as referenced in the canon, finds life in this 1976 Warner paperback.

"A story for which the world is not yet prepared..."

That is how Sherlock Holmes described the fantastic tale of THE GIANT RAT OF SUMATRA in his "The Adventures of the Sussex Vampire." Dr. John Watson, in deference to Holmes' wishes, kept the chronicle a secret, stipulating in his will that only in the year 1976 could the particulars of the case be revealed.

Here it is! A tale that bears the mark of Holmes' deductive genius, Watson's faithful reporting and a plotting virtuosity that Sir Arthur Conan Doyle himself would have approved in the author, Richard L. Boyer.

Fifty years after his death, a bank vault in London is opened to reveal new material about the most fascinating fictional detective of all time. In their hilarious and brilliant new film, Billy Wilder and I.A.L. Diamond have recreated the world of Sherlock Holmes in an adventure never before imagined.
