Plot summary
Holmes arrives at Dr. John Watson's residence one evening in a somewhat agitated state and with grazed and bleeding knuckles. Much to Watson's surprise and horror, Holmes had apparently escaped three separate murder attempts that day after a visit from Professor Moriarty, who warned Holmes to withdraw from his pursuit of justice against him to avoid any regrettable outcome. First, just as Holmes was turning a street corner, a cab suddenly rushed toward him and he just managed to leap out of the way in time. Second, while Holmes was walking along the street, a brick fell from the roof of a house, just missing the detective. He then called the police to search the whole area but could not prove that it was anything other than an accident. Finally, on his way to Watson's house, Holmes was attacked by a thug armed with a cosh. Holmes managed to overcome his assailant and handed him to the police but admitted that there was virtually no hope of proving that the man was in the employ of the criminal mastermind.
