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.

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.

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.

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.
