Over at A Podcast to the Curious, Will and Mike talk about M.R. James' story written for Queen Mary's huge, posh dolls' house. As always it's a very interesting chat with lots of background detail and anecdotes. Also, there are links to notes and other information.
If you're familiar with the story, you'll recall that it's one of the more nasty MRJ yarns. It features the killing of innocent children (as in 'Lost Hearts') and a supernatural device that the author himself admits is a reworking of 'The Mezzotint'. For some reason I like this one - it seems to add up to more than the sum of its parts.
