[McMurphy]

Leto touched on the Dark Tower one that you may wish to check out because it is a vampire novella rather than a short story. The King novella, which can be found in Legends: Short Novels by the Masters of Modern Fantasy, Vol. 1 (edited by Robert Silverberg) is entitled "The Little Sisters of Eluria." In paperback form, the story is 122 pages.

It is a good story, and I actually found it stronger than the third volume of the Dark Tower series and more intriguing than Salem's Lot. You don't need to read the Dark Tower books to understand the "The Little Sisters of Eluria," in case you were worried.
