Mr. Chameleon - The Case of the Jewels of Death

In New York City, after one o'clock in the morning, the doorbell to Helen Casey's west side apartment is ringing. As she slips on her robe, she says to herself "Who can that be? Perhaps I shouldn't go to the door, but, it might be something important". She opens her door slightly and says "Yes, who is it? What do you want?" At first, she sees no one. She opens the door wider and says "Why, there's no one out here. They must have gone". Then, she says "Oh, it's you! I want to explain. I've been wanting to explain to you!" Suddenly a loud scream is heard. An hour later, Cyrus Allen, a pawnbroker, living in his business on the east side, is awakened by someone pounding on his front door. He says "All right, I'm coming. Merciful Heavens, what sort of hour is this to get a man out of his bed? Can't they see the place is closed? He opens the door and says "Yes, you! What are you doing here? You've never come here before! I've been wanting to explain to you. If you just give me a chance to explain to you, oh no! Again, a loud yell is heard. At central headquarters, the following morning, Mr. Chameleon is talking with the Commissioner of Police. He says "It is very strange, Commissioner, that this woman, Helen Casey, who lived in a swanky apartment on the west side, was killed in the same manner as Cyrus Allen, a pawnbroker on the east side".
