Hm, that's unpleasant. 😕 I'm unable to listen right now and I didn't want to link to somewhere that had a plot synopsis or other spoiler equivalent, so I thought an audio of the actual story would be fine. I fixed it just now to link to something more cryptic but probably also less off putting.
For my money Stephen King’s old short fiction - Skeleton Crew, Night Shift, Different Seasons, stuff like that - is some of the best stuff he has done. And “Mrs. Todd’s Shortcut” is one of the best of that good lot to me.
