How Arthur Conan Doyle invented the killer mummy

Thanks to Mark Gatiss’s yuletide adaptations of the terrifying Edwardian ghost stories of MR James, sleepless nights spent cowering at the prospect of a much less benign visitant than Father Christmas have become a festive tradition in recent years.
