The Emerald Necklace

I stepped into my house when I heard a dreadful scream coming from up stairs. I continued walking hurriedly trying to find where the sound was coming from. I heard the scream again, this time it was louder and deadly. There is someone other than me in the house, I just knew it. I went to go investigate but what stopped me was madly horrifying. The door slammed shut abruptly. I turned around to end up face to face with my worse enemy Charlatan. The scary thing was that he was holding my emerald necklace.
