The Ghost Train - Newspaper Ad

San Francisco Examiner - June 10, 1927
Another one of those comedic and, at the time, innumerable 'Old Dark House' mysteries, where the haunting gets explained away as a cover to scare away any and all potential witnesses. Only this time it's a train, not a house.

My introduction to these tropes came via their being recycled and repurposed for the original Scooby-Doo series, long before the decision was made to turn the make-believe ghosts and whatnot real.
