Sherlock Holmes is goaded into a boxing match, in which his opponent, Sailor Mackenzie, loses both the bout and his life. All but Mrs. Hudson and her colleagues, Holmes and Watson, are convinced the fighter's death was an accident. The Baker Street trio travels to McLellan Manor in Yorkshire to sort through the numerous people who have reason to celebrate Mackenzie's death and the opportunity to cause it. Complicating their investigation, Holmes and Watson are asked to become protectors for Lily Langtry, and Mrs. Hudson to become her lady's maid, when the famous beauty is threatened by her latest paramour, the volatile George Baird. Before all can be resolved, Holmes will need to lead a séance in which he will call on a ghost to solve a 35-year old murder, and Mrs. Hudson will find herself in surprising alliance with the Jersey Lily.

It is 1896. Mrs. Hudson and her colleagues are traveling to Athens to attend the first Olympiad in more than 2000 years. Indeed, Holmes is to participate in the foils competition as a member of Great Britain's Olympic team. But the trip is more than just fun and games. The three members of London's first and foremost consulting detective agency are, in fact, engaged in a delicate bit of undercover work on behalf of Queen and country. They are to secure a letter being sent by courier to Queen Victoria from her daughter, the Dowager Empress of Germany. Peace between the two nations may well depend on the contents of that letter. They arrive to find both the courier and the wife of the British Ambassador shot dead in the Ambassador's residence. The letter and the Ambassador are nowhere to be found. They discover, too, that Inspector Lestrade is already in Athens investigating the sale of fake antiquities to the wife of the Ambassador. The Baker Street trio has the ten days of the Olympiad to recover the critical letter, capture a double murderer, and uncover the secret behind the scheme to pass off copies of Greek antiquities as genuine-all while Holmes seeks to dispatch his fencing competition and win an Olympic medal.

A mystery is afoot at 221 Baker Street, but will Griffin Sharpe be able to figure out the clues before the future catches up with the past? When Sherlock Holmes moves out of Baker Street, a new tenant moves in-a mysterious woman named Elizabeth who has long been a fan of Holmes. When she discovers that Griffin and his uncle are also detectives, she becomes very friendly. So when Elizabeth goes missing along with a special invention, Griffin sets out to rescue her. But finding Elizabeth will take them on a race against the clock that bends time itself!

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." Soon Holmes finds himself matching wits with a man who will steal anything - if the price is right. Moreover, this thief will go to any lengths, including blackmail and murder, to achieve his desired goal. As Holmes comes to understand his adversary, he also begins to realize he can only react to the Merchant because he has no idea where this criminal mastermind will strike next. All Holmes knows for certain is the Merchant seems to specialize in priceless, one-of-a-kind articles. Will that be enough information for the Great Detective to outwit his foe? From the British Museum to the Louvre to Blenheim Palace, Holmes finds himself in a deadly game of cat-and-mouse. Set against the backdrop of early Edwardian England, the Great Detective and his Boswell encounter an array of luminaries from the Duke and Duchess of Marlborough to a young Winston Churchill. For fans of Conan Doyle's immortal detective, the game is always afoot. However, this time around Holmes must try to bring to justice a villain who might well be the next Napoleon of Crime.

Alex Byrne sets out and defends a theory of self-knowledge-knowledge of one's mental states. Inspired by Gareth Evans' discussion of self-knowledge in his The Varieties of Reference, the basic idea is that one comes to know that one is in a mental state M by an inference from a worldly or environmental premise to the conclusion that one is in M. (Typically the worldly premise will not be about anything mental.) The mind, on this account, is 'transparent': self-knowledge is achieved by an 'outward glance' at the corresponding tract of the world, not by an 'inward glance' at one's own mind. Belief is the clearest case, with the inference being from 'p' to 'I believe that p'. One serious problem with this idea is that the inference seems terrible, because 'p' is at best very weak evidence that one believes that p. Another is that the idea seems not to generalize. For example, what is the worldly premise corresponding to 'I intend to do this', or 'I feel a pain'? Byrne argues that both problems can be solved, and explains how the account covers perception, sensation, desire, intention, emotion, memory, imagination, and thought. The result is a unified theory of self-knowledge that explains the epistemic security of beliefs about one's mental states (privileged access), as well as the fact that one has a special first-person way of knowing about one's mental states (peculiar access).
