In the run up to Christmas, The Guardian's Weekend magazine Saturday supplement included four Christmas ghost stories. Whilst they were all good, Jeanette Winterson's Dark Christmas deserves a special mention. Pick of the bunch though, for me, was Light and Space by Ned Beauman, a terrific piece of psychological horror that inevitably prompted the "I wish I'd written that" feeling in me that I think most aspiring writers feel on a semi-regular basis. Bottom line? Light and Space is the best short story I read in 2013.
You can find all four stories online here.The website also has a bonus fifth story, from Penelope Lively.
