disclaimer I DO NOT OWN Sherlock Holmes is commissioned by Mycroft to investigate the suspicious death of a government employee who was working on a top-secret defence project: the Bruce-Partington Project.[5] After apparently rejecting the case and handing it over to Watson, Holmes begins to be taunted by a criminal who puts his victims into explosive vests and sets Holmes deadlines to solve the apparently unrelated cases, which include a twenty-year-old cold case involving the shoes of a drowned boy, the disappearance of a businessman, the death of a TV personality and the death of a guard of an art gallery at the hands of an assassin called the Golem. As Holmes solves the cases, he finds links between them. After clearing up the original case of the civil servant, Holmes tries to force his unseen adversary to reveal himself. Near the end of the episode Holmes and "Jim Moriarty" reach a standoff and Jim reveals that he is responsible for the crimes. In the final seconds Sherlock Holmes points his gun at a bomb on the floor that was strapped to Watson.
