I reread this after seeing the Bob Savage movie based upon the short story. (side note, is "based upon" different than "adapted from" when used in movie credits? Hmmm...)
I've always thought this was a very chilling little story. You obviously have to put yourself in the time at which it was written because it, and the ideals of the father in the story, are very, very outdated.
A man who has lost three children in seemingly unsuspicious ways, visits a psychologist to tell his side of the story. He does not believe there was anything natural about their deaths. He believes the boogeyman killed them all.
Props to King for a seemingly throw away comment. The patient is giving some backstory and mentions that his mother thinks his wife is trash because look how quick she was to sleep with him before they were married. The psychologist responds with "On the other hand, look how quick you were to sleep with her before you were married." It's a small thing, but shows King's mindset and feelings at a time when the majority of people would have agreed, erroneously, with the patient!
The movie was fine, but I think it could have been much more effective as the kind of calm, event free tale as told on the page. I wish someone would adapt it almost word for word, scene for scene, with maybe some background filler, as King told it. Seeing the boogeyman isn't necessary to instill fear. The very idea of one is enough.
