Smee by A M Burrage is consistently rated as one of the scariest Christmas Stories there is. It has it all: a large Country House, Christmas Eve, a group of people who don’t know each other and a reason to be wandering around in the dark!
If you liked this, why not try The Kit Bag? It is of a similar period and also has things half seen in the dark.
