The heavy rain fell outside, and dark clouds covered the sky above the city where the crime occurred yesterday morning. The detective looked at the body on the floor and found a sharp silver blade gleaming brightly under the light now. The nervous suspect stood silently in the corner of the room watching the detective wearing a very old brown coat. The thick silence filled the air while the red blood dripped slowly from the knife onto the floor making loud splashes. The detective turned to the suspect and asked him a serious question with a sharp tone about the dead man here.
