"Well, yes, I did. For one thing, I don't believe Ratchett was his real name. I think he left America definitely in order to escape someone or something. I think he was successful – until a few weeks ago." (1.6.72)
We quickly learn that even Ratchett himself had assumed a false identity in order to escape his past. No one on this train is who they seem to be.

"I mean," explained Poirot, "that if the murderer intended us to believe that he had escaped by the way of the window he would naturally make it appear that the other two exits were impossible. Like the 'disappearing person' in the cabinet – it is a trick. It is our business to find out how the trick is done." (1.7.138)
Poirot likens the murderer's methods to a magic trick, suggesting that the events have a certain theatrical flair to them.

"Mr. Hardman sighed, removed the chewing gum, and dived into a pocket. At the same time his whole personality seemed to undergo a change. He became less of a stage character and more of a real person. The resonant nasal tones of his voice became modified." (2.9.33)
Mr. Hardman reveals his identity to Poirot, and that he has been working undercover. However, he doesn't reveal his connection to the Armstrong family.
