Sir Arthur Conan Doyle on film! In this 10-minute filmed interview from 1928 he discusses Sherlock Holmes and spritualism.
No, no pipes in this film. But, he was a pipe smoker, and as is my wont I occasionally post items Holmesian interest because it's my blog.
And on a personal note, oh how I would love to have such a clip of H.P. Lovecraft, just to hear what his voice sounded like.
