Where Houdini Lives
Behind Neil's left shoulder down the hall. That's the room where the photos of HH at his desk with books piled around him were taken?
Yep, that was the library and that pic of HH is him at his library desk. More here.
Do you remember the size of the library?
It was presumably the whole room. It's big. It's now the master dinning room. Click the link I put in my comment and scroll down to the map of that floor. It's the full back room.
Got it! Thanks!
