"Firstly, at Neil's house, guess what I found when I was checking the scent?" Pannis sneered: "I found that indeed two people had last left his house, one being him, but surprisingly, the other one wasn't Betty, but a stranger. Isn't it supposed that given the current situation, Betty should have fled to Neil's house and then the two of them should have left together by sled? Why was the other person a stranger instead? Of course, this doubt could be explained by their agreement to meet elsewhere, although this explanation may not seem very reasonable."
