Phillip had disappeared.
According to the woman, she had brought a rail cop to look for Phillip as soon as she found out her teacher was missing last night. At that point, he was still in the room, exuding an air of innocence under her intense questioning. However, from this morning onwards, there had been no sign of him. After asking the train staff, she found out that Phillip had not shown up since the morning.
Well, this is interesting.
Two people disappearing successively on a speeding train, this case is even more interesting than Conan's cases. Of course, Duanmu Huai didn't need think about what method was used. When he learned that Phillip was related to the Silver Dusk Cottage, he guessed that the other party was most likely a cultist. If his speculation was correct, then the woman's teacher was probably threatened by Phillip during his exclusive interview, thus leaving such a message to her afterward.
