Hi, I'm posting for my mom. She has been following MaG's walkthrough for this game. I played it years ago. She says she's done everything in the walkthrough except talk to Dr. Constantine at the very end, who won't talk to her. (He says he's said all he's going to say.) She still has a footprint in a cake mold in her inventory. In her documents, it says she hasn't used the telegraph machine, which she has. I tried it myself and the telegraph machine wouldn't let me use it. Poirot keeps saying to keep investigating and go back over what has already been checked. In her documents, it says "Search train for evidence suspects may be lying about their pasts."
Can anyone think of what she might have missed? I've looked at her game, but short of replaying it myself, I don't think I can help. She's at the very end, so if no one knows what she's doing wrong, it would be nice if she could just get a save for the ending.
Thank you to anyone who can help!
