5- A dark secret

I was alone in my home resting on the sofa of my living room when someone knocked my door.
Because I invited a friend to my house, I expected to hear that noise on the door. Even though I was not sure who was there, I went to open the door.
I saw two police officers looking at me, their faces were very serious whereas mine was pale, because while they were there in the entrance, I had hidden my darkest secret in the basement of my house, there I had a chest that I found when I arrived at that house, full of jewels that I didn't plan to return, I was not going to let anyone try to take my chest away, so I took care of them.
