Jiang Yao curled her lips and said, "His expression wasn't right? Well, we don't need to make any guesses. It must be the person who asked him to do that. Sergeant Hu's father was conflicted, so the expression on his face was not right. Oh, right, did the boss of the snack bar say whether the person was a man or a woman?"
Lu Xingzhi said, "The boss was the one who answered the phone. He thought it was a man, but his voice sounded strange. Maybe the other party was deliberately speaking in a different voice. We can only say that it is more likely to be a man, but we can't rule out the possibility that it is a woman."
People like that should be well prepared, so they would know to change their voice. Sergeant Hu's father's suicide note did not mention that person at all. Even though Sergeant Hu's father had committed suicide due to guilt, he still wanted to protect that person.
