ooohhh...now my interest is piqued. Must get it out of the library. I grew up in a town that had/has a Knights Templar castle, and loads of local folklore about the corruption and debauchery of the knights. There was a secret passage from the castle down to the river, I never went further than 10 feet into it from the river end, I believe it was blocked further in. The last book that kept me up all night was a Steven King book, think it was called Red Dragon, something like that. Scary!!! :^(
