Mrs. Hubbard is revived, and the three men head to her compartment. On the floor is a cheap dagger, "sham Oriental," with rust on it (2.14.17). There are no fingerprints, of course.
The man must have slipped into Mrs. Hubbard's room, put the knife in her bag, scared her, and then fled. Right? Well… Poirot's not convinced.
Mrs. Hubbard comes in and is freaking out. She asks to be moved, so they take her to compartment No. 12 in the adjoining coach, which is identical to the one she's in now.
Poirot also figures out something else about the bolted door: the door appears to be bolted if it's locked from the other side. That must have been what happened. The Swedish woman must have checked the door and assumed it was locked – but it was only locked from the other side.
Mrs. Hubbard rambles on when Poirot asks her if she visited Smyrna. No, she sailed to Stamboul and a Mr. Johnson met her there.
Mrs. Hubbard needs some coffee. They search her bags (there's nothing else unusual there) and then head out to conduct the rest of the search.
