Séamas Duffy’s fourth novel, Sherlock Holmes and the Sixty Steps, follows a similar format to his previously published Holmes collections: a novella together with some shorter stories. The four stories are: “The Tragedy of Langhorne Wyke” (1890); “The Mystery of the Thirteen Bells” (1895); “The Adventure of the Sixty Steps” (1897); and “The Problem of the Coptic Patriarchs” (1898).

“From now on, I am going to be Sherlock Holmes, the World’s Greatest Cat Detective.” With those words, my friend Spot decided he would become a crime-solving kitty. “And you, of course,” he said dramatically, “will be my faithful friend, Dr. John Watson. The one who writes down all of my adventures and shares them with the world! We’ll be famous! Everyone will know the name ‘Sherlock Holmes, the World’s Greatest Cat Detective’!” I wasn’t too worried. I was sure that, by morning, Spot would have forgotten all about becoming Sherlock Holmes. Boy, was I wrong.

Undershaw was the Surrey home of Arthur Conan Doyle between 1897-1907. Built lovingly for his wife Touie to help treat her ongoing battle with tuberculosis, Arthur created a haven for his wife and family. It was here he wrote The Hound of The Baskervilles, brought Sherlock Holmes back to life in "The Empty House", and entertained guests such as writer J.M. Barrie, illustrator Sidney Paget, renowned actor William Gillette, and more.

The Keys of Death is Baker Street bedrock. In Gretchen Altabef’s 1880 novel, Sherlock Holmes, Doctor Watson, and Mrs. Hudson begin something great in the world.

A client forsworn, a threatened town, and a Goliath of unimaginable proportions. Sherlock Holmes has survived a three-year vendetta against him by Moriarty’s remaining henchmen. Wounded and bleeding, with Mycroft’s help, he clandestinely boards an Atlantic steamship. At the close of his great hiatus, Holmes finds sanctuary at Vassar Women’s College. This radical challenge entangles him in the web of a nefarious mystery. Its unraveling involves New York’s most revolutionary residents: Elizabeth Cady Stanton and Susan B. Anthony.

Sherlock Holmes' adventures continue in seven surprising cases. Holmes and Watson investigate an alleged haunting at the Diogenes Club, vandalism at a prominent art gallery, the case of a frightened amnesiac, the takeover of 221B by vicious criminals, the sequel to "The Engineer's Thumb," the defiling of Holmes' Stradivarius violin, and a Christmas story featuring a graveyard with angry insults carved into the headstones. The game is afoot!

Sherlock Holmes thrives on danger. Sudden knife attacks, being stalked, and facing a network of assassins present little more than a cheery break in the monotony. But the enigmatic Lady Beatrice presents danger of a different kind. Is she a murderer or a potential victim? Or something even more perilous? Uncovering her secrets could change Holmes's life forever, and in ways even he cannot anticipate.

Sherlock Holmes' investigations were not always the neat and self-contained stories that were presented for publication. Holmes' cases overlapped one another considerably, often with the next beginning while the current was still in motion. Some moved linearly from start to finish without interruption while others stretched, a piece here and a piece there, across weeks, months, or even years and decades.

From some clear pieces of glass and a raven's feather, the great detective must divine exactly who the client was and what prompted him to seek assistance at 221B. Fortunately, Holmes has a number of experts upon whom he can rely as well as his own vast store of esoteric knowledge. Treading a twisted path, Holmes soon finds himself matching wits with an unseen criminal, who appears to be the equal of the late Professor Moriarty. At the same time, he is tasked with sparing the monarchy any possible embarrassment that may stem from the investigation.

But when one of his rare bursts of prosperity enables him to buy two strikingly good pictures from a pawnbroker, Mycroft Holmes takes a remarkable interest. And what is the meaning of the little rhyme that runs round the canvas of the painting.
