Continuing on with the classic Universal Sherlock Holmes films (this list on YouTube has good quality versions of them all (for now, at least)), The House of Fear. It’s a good one, with marvellous characters actors with great faces.
Holmes and Watson in an lonely old Scottish castle, caught up in a mystery. A great image of the immortal pair.
(The castle, I must note, is on the North Atlantic shore, but the ground floor rooms facing the ocean have walls of French windows with inadequate latches, which burst open at every storm. Why this wasn’t fixed one or two hundred years ago is an unsolved mystery.)
A shelf full of mystery novels, including Murder in the Cellar, Death by Night by Archibald Brown and Murder as a Fine Art. I think these are meant to look like the Crime Club series.
