There's a rather good comic strip version of 'Wailing Well' here. It's well-drawn and reminds me of the more 'sensible' comics of my youth, such as the Victor, and all those Commando stories of the world wars. The artist, Anna Sahrling-Hamm, is to be commended for taking the story and treating it so well. It's not quite a scene-by-scene retelling of M.R. James's tale, but I think the slight changes are rather good.
