The story begins in modern day, several children are playing in an attic, where they discover a book, chronicling one of the many mysteries of the detective Sherlock Holmes. They read the story, being very interested in the mystery.

The following morning, an article in the newspaper accuses Holmes of the theft, Baynes arrives and with the necklace, which he reveals is a cheap imitation and everything seems to incriminate the detective. However there is no solid evidence against Holmes, and he says he will look into it further.

During the next sequences, Holmes tells Watson he has an immediate appointment with the Bishop of Knightsbridge. Upon arriving, he discovers that the bishop has been tied up, burnt and mutilated, as well as a finger that presumably belongs to one of the murderers. Holmes deduces that the culprits had been low class workers, who had been hired, and given a special poison that caused a form of psychotic madness. Upon further investigation, Holmes pinpoints the location where he believes the men to have worked, a cemetery in Whitechapel. The player is then given a choice where to go next. To visit the cemetery, or to a local prison which houses a poison manufacturer.

Holmes manages to get Scheilman what he wants in return from information on the poison. A fire begins in the cell blocks, causing confusion among the guards. Watson volunteers to help make sure the prisoners are all still in their cells only to discover that Scheilman has escaped. Holmes and Watson leave, and wait out behind the prison, where Holmes claims to e meeting someone. Spotting a figure nearby, Watson realizes that Holmes helped Scheilman to escape.

He tells Watson he will meet him at the next investigation.

They look around his apartment and find clues that indicate he was involved in the Bishop's murder. They also find opium paraphernalia. They perform an autopsy and discover that his opium had been laced with the same poison that had been used on the Bishop. They go to the nearby opium den and discover the other men involved in the murder, though they are apprehended by Scotland Yard. Holmes and Watson leave, despite Watson's protests.

Holmes wants to question the Bishop's nephew, Henry. They go to the address where he rents a room, and discover that someone had been watching the house. They check his room, and notice that he had left in a hurry, and even more worryingly, appears to be armed. They find clues that indicate he is laying low at the Wharf 321. Holmes heads to the Wharf, along with his dog, Toby, to track down Henry. He finds him within a smelting plant, however Henry holds Holmes at gunpoint, but is accidentally knocking into molten metal by Toby, killing him.

With the trail dead, Holmes decides to visit O'Farley, a journalist who had written a slanderous article accusing Holmes of the theft of the necklace. O'Farley rushes out when Holmes arrives. Holmes takes the opportunity to break into and search his office. Discovering that he seems intent on proving Holmes is a fraud, has information on Prince Woodville and also had a visitor, whom left moments before Holmes arrived. Holmes discovers a secret exit, that the visitor used, and pieces together that the visitor was a judge.

Watson goes there and confronts Holmes, who is disguised as an old woman. Holmes tells Watson he is heading out of the city to continue the investigation.

They arrive at a Sawmill, which is inhabited by three Russian anarchists, who seem to be representative of the three wise monkeys(One is blind, one is deaf, one is mute), who Watson holds up and questions while Holmes looks around upstairs, finding the body of a deceased magician who previously lived there. Holmes sets the place on fire, causing a panic among the brothers, who flee when Watson calls out to Holmes, one of the Brothers warns that Sherlock Holmes is dangerous and shouldn't be trusted.

Holmes apologises to Watson for his behaviour, and reveals that he needed to fake his death in order to continue the investigation unhindered. Holmes reveals everything he knows to Watson.

It turns out that Professor Moriarty, has been plotting to cause panic, by poisoning the poor of London, using the same poison used on the bishop, which is being mass produced by Scheilman, by mixing it into the soup from Prince Woodville's soup carts. This would cause the poisoned people to riot and kill anyone in their way, and then eventually die themselves from the poison, which would result in the deaths of thousands. As well as this he planned on removing the queen from power. This would create mass hysteria and a massive power vacuum, which Moriarty would fill by putting Prince Woodville on the throne, who now had a great public image, giving Moriarty control over Woodville, and in turn, the British Armed Forces.

Holmes and Watson, go to stop Moriarty's scheme, by going to his hideout, an old carnival near a disused and dilapidated factory, where the poisoned soup is being made. Holmes and Watson incapacitate the guards and continue their investigation. They discover the three Russian anarchists also have made bombs that will go off via radio transmitter, at key locations including Scotland Yard. While trying to to find out how to disarm the bombs, They find Prince Woodville, who they tell they are working for Moriarty. Not believing them, he holds Watson at gun point and demand Holmes bring Moriarty. Homes incapacitates Woodville and hides his body. Holmes and Watson split up, Holmes to call and warn Inspector Lestrade, who had returned after Bayne's death, about the bombs he also learns that Moriarty is not in control and he is merely a puppet. Watson builds a bomb to better understand it, and figures out it must be disconnected from the radio tower before being disarmed. He returns to Holmes with this information, and his newly constructed bomb. After disconnecting the bombs from the radio transmitter, Holmes and Watson decide to use their bomb to destroy the factory producing the soup. They make their way there via cable car, which is stopped by Moriarty. Holmes and Watson send the bomb down the cable causing it to detonate on the roof killing several of Moriarty's henchmen and destroying the factory.

Holmes and Watson return to Moriarty's quarters to find out who was controlling Moriarty, who suddenly appears, badly burned by the explosion and brandishing a gun. Holmes casually asks if Scheilman was immune to his own poison. Suddenly a feral Scheilman attacks Moriarty, and savagely bites at his throat, Moriarty shoots him, but is too late to save himself. With his dying breath, Moriarty, asks Holmes to take care of his daughter, Katelyn Moriarty, as he is the only one worthy to teach her.

Holmes takes the child and treats her as a daughter, giving her an education life. In turn he finally has a family of his own.


The player takes the role of Sherlock Holmes for the majority of the game, though there are also sections in which they control Dr. Watson and one where Toby, a basset hound, is controlled.

An ability called 'sixth sense' is available, which will briefly highlight all the objects which can be interacted with in the player's field of view; this ability must then be allowed to recharge before it can be used again. Once discovered, clues are added to a 'deduction board', a gameplay mechanic which involves linking pieces of information and select from a number of possible deductions. Once all clues are discovered and the correct deductions selected, the story progresses. There are also several puzzles which must be solved, most of which take the form of locked puzzle boxes.

Three camera views are available – a first person point of view, an over-the-shoulder camera and a static third person camera. The player is able to change between them at any time.
