A Sherlock Holmes Adventure

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.

When the papal apartments are burgled in 1901, Sherlock Holmes is summoned to Rome by Pope Leo XII. After learning from the pontiff that several priceless cameos that could prove compromising to the church, and perhaps determine the future of the newly unified Italy, have been stolen, Holmes is asked to recover them. In a parallel story, Michelangelo, the toast of Rome in 1501 after the unveiling of his Pieta, is commissioned by Pope Alexander VI, the last of the Borgia pontiffs, with creating the cameos that will bedevil Holmes and the papacy four centuries later.

Reluctantly, Sherlock Holmes agrees to assist Inspector Lestrade who is being hounded by an obnoxious nobleman whose jewel-encrusted dagger has gone missing. However, what Holmes initially believes to be a simple theft turns out instead to be his first encounter with a master criminal, who is as ruthless as he is brilliant and whom Watson dubs "The Merchant of Menace".

After surviving an attempt on his life in Paris, Sherlock Holmes returns to London, where the great detective is almost immediately enlisted by his brother to secure the safety of the delegates at a top-secret peace conference. With Europe a veritable powder keg in the years before World War I, Holmes understands any misstep on his part could prove fatal and possibly plunge the continent into war. However, after pledging to do his utmost for "King and Country", Holmes suddenly finds himself overwhelmed by an onslaught of cases.

On the morning of the vernal equinox in 1899, Holmes is roused from his bed by Lestrade. The inspector has received a report of a girl brutally murdered at Stonehenge. Upon arriving at the famed site, Holmes discovers the body of a young woman. On her forehead, painted in blood, is a druidic symbol. On her side, also in blood, is a message written in a strange language that neither Holmes nor Lestrade can decipher. The girl was also eviscerated and her organs placed around her body. As a final touch, branches from yew trees had been artistically arranged around the corpse. Holmes senses a malevolent force at work, but without data, he is powerless. As the weeks pass, he slowly gathers information about the ancient druids and Celtic mythology and begins to assemble a small army of experts to assist him.

During the elaborate funeral for Queen Victoria, a group of Irish separatists breaks into Westminster Abbey and steals the Coronation Stone, on which every monarch of England has been crowned since the 14th century. After learning of the theft from Mycroft, Sherlock Holmes is tasked with recovering the stone and returning it to England.

A quiet morning at Baker Street is thrown into turmoil by the arrival of Inspector Lestrade, who informs Holmes a man's body has been discovered in the Tower Bridge that was then under construction. That grisly event proves to be the opening salvo in a terrifying game of wits between Holmes and an unknown adversary.
