    Like a magician, Holmes took out a ring and said, "This one will do. It is very much like that one." Just as he expected, after the clock struck 8:00 in the evening, an old woman with wrinkles all over her face came for the ring. She said, "That is my daughter's ring. She lost it when going to the drama yesterday evening." Watson picked up the ring, wrote down her name and address, and gave it to her. The old woman left gratefully. Holmes followed her out. But he lost her half way. He went to the address Watson wrote down. There was no such person there. Holmes concluded that the old woman must be acted by a young fellow. Otherwise she could not escape so easily.
    The next day, after they had breakfast, Detective Gregson broke in. His assistant reported that Stangerson, Drebber's secretary, was killed. The policeman who found Stangerson's body said that the death had been made by a knife stabbing into his heart. On his face had been written the same word with blood 'RACHE'. Behind the hotel in which the dead person stayed, there was a little alley heading toward a coaches' storage. When the kid who delivered milk had been walking on the little alley, he had spotted the ladder, which always laid on the ground, put against the window of the dead person's room. The kid looked around unawares and saw a tall person with a red face, wearing a brown coat, came down from the ladder. No money was lost, which meant the murderer was not for money.
