Here's an item from the February 23, 1926 Reading Times that shows things didn't always go smoothly for Houdini during the Spiritualist exposé portion of his full evening show. Although, I'm not sure which is worse; Houdini having to admit he was wrong, or the newspaper referring to him as "the little magician." Enjoy.
I'm guessing the "girl detective" here was Rose Mackenberg. Thanks to Patrick Culliton, Houdini's Ghost, for sharing this one.
