Merry-Go-Round Scene from Hitchcock’s Strangers on a Train

MovingToyshop_PB-226x345I ‘ve just finished reading The Moving Toyshop and I’ve read in Wikipedia that the book provided the source for the famous merry-go-round sequence at the climax of Alfred Hitchcock’s Strangers on a Train. All the major elements of the scene: the two men struggling, the accidentally shot attendant, the out-of-control merry-go-round, and the crawling under the moving merry-go-round to disable it, are present in Crispin’s novel, though he received no screen credit for it.
