This one goes way back, but it’s a good one. If you enjoy weird books with a fantasy/sci-fi lean, and if you have a penchant for Victorian romps featuring real-life characters from history, and if you like the occult, and if you like alternate universes, and if you like Sherlock Holmes tales–then you might like F. Gwynplaine MacIntyre’s The Woman Between the Worlds. I happened to be watching television one night when the great Harlan Ellison recommended it on the Sci-Fi Channel. This book is truly weird, and truly a lot of fun.
