Pursuit - Pursuit on the Night Ferry

Scotland Yard had received word from an informer that the Night Ferry Express Train was to be held up on its run. At what time and exactly where was not known. So, Inspector Peter Black, his assistant Moffatt, Railroad Inspector George Hobson, as well as ten other men were making the journey in the hope of intercepting any attack. They had boarded the Night Ferry Express at 9:00 PM from the Victoria Station. There would be no halts until Dover, at which point the train would be run aboard the ferry and transported across the English Channel to Dunkirk. From there it would continue through to Paris. Trouble was expected somewhere between their present point and the final destination. After listening to some French passengers complaining about the food in the dining car, Hobson says "What's the time, Black?" Black says "It is 10 o'clock". Hobson says "I wouldn't mind a bite to eat myself". Black says "You'll have to wait until Dover for that. It's only 40 minutes". Hobson says "Well, if something's going to happen, I hope it's before the channel". Black asks "Do you get seasick, Hobson?" He says "Violently, don't talk about it". Black says "I won't. Look, hang on here will you? I'm going to see how Moffatt's getting on". After a few seconds, Moffett says "Hello, Sir". Black asks "Everything quiet, Moffatt?" He says "Nothing doing up here, Sir". Black says "Right. Well unless they're planning to stop the train when we get over to France, I don't think that I...." Moffatt says "Look out, there's a light up ahead. Something is on the rails, I think". Black says "Alright, you jump for it the second the train stops, Moffatt, and have your gun ready".
