Ghost stories are closely tied to Christmas. The world’s most famous ghost story and most famous Christmas story are the same thing: A Christmas Carol, by Charles Dickens. The guy who is often hailed the greatest writer of ghost stories, M.R. James, used to compose his specifically for readings at Christmastime. In the tradition of James–and with a macabre, twist-at-the-end dash of Edgar Allan Poe–Andrew Klavan offers “The Advent Reunion.” It’s a ghost story in five video chapters, takes about 25 minutes in its entirety, and is well worth your time.
