Hey everyone! Okay, so here's my problem:
Spoiler:I've done everything so far. I've gotten all the passports (including Hardman's second passport), all the passengers' fingerprints, all the fingerprints around the train, and I've compared the footprints, finding the perfect match. All this was confirmed by Poirot. Now when I go to talk to him he tells me "You must complete the investigation, and don't be affraid to go over grounds you have already covered". I can't see what else I need to do, and all the passengers just sit around and tell me to talk with them later. It's really frustrating. Can anyone help me? Thanks in advance!
