1)What can our Sleuth actually find? For logistic purposes, I want Villain to remain in possession of the actual tickets -so I am thinking of some type of receipt? Would there be a receipt or stub?
2) I have discovered from searching for "Vintage Travel Ocean Liner" that it was possible on New York lines in the 1920's to prepay a ticket in advance, and use it on an unspecified future sailing - was this a common practice in the business everywhere?
3) If Villain wanted to get out of the country first and took the Golden Arrow boat-train connection from London-Dover-Calais, what Continental ports would be most likely for a Transatlantic route?
