"Secret Room" and Brutus Morris: Stoker's Character Notes for Dracula
You may have to click on this a couple of times to zoom in, but it's definitely worth looking at. Quincey Morris was originally supposed to be Brutus (can you imagine?) and there's a note about a "secret room." I also love the scratch outs, and the insistence upon Wilhelmina, called Mina. You can also find another version here if you can't zoom in enough from this entry.
Good stuff. Reminds me of seeing the plot of "A Fable" written out on a wall in Faulkner's house. And can you imagine how different the book would be if
