Holmes agrees to satisfy Watson's curiosity about the memento by recounting the decades-old history of its subject.

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.

With two of their own under threat, the pressure is mounting to catch and stop the group known as "Hellfire Heirs".

An enigmatic jewelry case, holding human remains, arrives at the cottage of Sherlock Holmes, enticing him from his retirement refuge in the Sussex Downs.

The two find themselves battling forces arising from a time before England was a country - when the Celts were fighting for survival. Though set in 1919, The Celtic Phoenix is steeped in the enigmatic culture of the ancient Celts who reigned over much of Europe 3,000 years ago.

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.

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.

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.

In the year 1908, Holmes believed himself to be in retirement. Watson was once again in private practice and unwed. Mrs. Hudson had gone to Sussex to act as Holmes's housekeeper. But the fates had agreed that Martha Hudson and John Watson should be together. Or had they? When Dr. Watson proposes to Martha Hudson, it sets off a series of events that only Sherlock Holmes can deal with. Watson has already had three wives—all have died under unfortunate circumstances. Colm Campbell, Martha Hudson's nephew, thinks there is more here than meets the eye.

Sherlock Holmes and Doctor Watson are summoned to Theobald Grange, the Warwickshire home of Lady Heminworth. Being of a nervous and superstitious disposition, her Ladyship lives in fear. Her husband and elder son were recently murdered, apparently by the ghost of a court jester who was executed on the site centuries before. The apparition has warned that she, too, is to die. Holmes rejects a supernatural explanation, although his adversary seems unaffected by gunfire and is able to take flight and disappear.

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?

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.

After rising to prominence for his role investigating the case of Jack the Ripper, former Detective Inspector Daniel Wilson is now retired.

So when a body is found in the Egyptian collection of the Fitzwilliam Museum in Cambridge, Wilson is called in.
