Spoiler Alert. They all did it.
Well the sleeper and diner were central locations in the plot. And this is the OE. I would expect that the diner was a place that made Downton Abbey food look like something from the Golden Arches.
And if it takes PE and current SHERLOCK type filming to get people involved with one of the best English writers of all time, so be it. BTW AG had trains involved in, I think, THREE of her works. But off hand I do knot know the names of them.
