Adrian Conan Doyle on his father's belief in Spiritualism

Here's an excerpt from an interview with Adrian Conan Doyle, son of Sir Arthur Conan Doyle, in which he talks about his father's belief in Spiritualism. No mention of Houdini here, but it's interesting to hear the family take on this fifty years (or so) after the fact.

You can watch the full three-part interview (which deals mostly with Sherlock Holmes) starting here.
