Sherlock Holmes is approached by Mrs. Hudson to assist a friend of hers. The lady also lets furnished rooms and is now worried about what one of her boarders may be up to. The man had come to her 10 days before and paid her an exorbitant amount to ensure complete privacy during his stay. His meals are left outside his door and no one enters the room. Now the landlady can't sleep at night wondering what the person is up to. Based on the available information, it's apparent to Holmes that the lodger is an Italian gentleman who had recently arrived from New York City. Knowing of recent crimes there, Holmes soon knows the man's identity and that he is running away from the head of a sinister group known as the Red Circle.
