One Week Was Allowed

I spent a very pleaseant Halloween with my daughter, her boyfriend and my lodger, which ended with my reading them 'Oh Whistle and I'll Come to You, My Lad'. It was the first time any of them had heard it, and I think I can say that it produced the desired effect (despite my halting performance in the Latin sections). I've promised another M. R. James classic for Christmas.

Which should I choose? 'Count Magnus' is the one that freaked me out the most when I first read it, but I'm not sure it's his best. 'The Mezzotint' and 'The Ash Tree' are justly celebrated, but if it's not too long (which I suspect it may be) I'm leaning towards 'Casting the Runes', which has one of my favourite final lines in literature.

Pondering that story as it might be seen by people in their 20s and 30s, it occurred to me that it may remind them of The Ring - with its time-delayed curse. Are there other examples of the phenomenon, especially pre-James? Plenty of curses only 'take' when certain conditions are met, but I can't think of any others that are on a simple time delay.
