"No way, Michael," DuoDuo dropped to her knees on the couch, "You might be mistaken! That's impossible."
"Come on, Miss Duo, calm down," Michael held DuoDuo's wrist, "Let me explain the details."
"Speak then, speak." DuoDuo anxiously urged, "Speak quickly."
Michael was still holding out the bullet shell.
"The first thing I found was not the bullet shell, but the bullet mark on the ground where Merlin pushed you. You must remember the situation then. Merlin suddenly turned around and pushed you, then she started coughing up blood holding her stomach, right?"
DuoDuo nodded, that's how things happened at that time.
