Whistle and I'll Come to You

This picture reminds me of a particularly creepy scene from Jonathan Miller's TV adaptation of a M.R. James short story.

"On this bleak stage at first no actor was visible. When, in the distance, a bobbing black object appeared; a moment more, and it was a man running, jumping, clambering over the groynes, and every few seconds looking eagerly back. The nearer he came the more obvious it was that he was not only anxious, but even terribly frightened, though his face was not to be distinguished."
