Ironic. When he commits a perfect crime that no one can point him as the killer (no one would even have an idea the cause of death) , then he would just say a clue , it's like he was literally speaking that ' I'm the culprit. You now know how he/she died. Now, find some evidence . '
I love this story but I understand, the creator also need to earn, it's like a reward for creating such wonderful story.
