The Winchester House

I remember seeing a tv documentary on Sarah Winchester and the Winchester Mystery House, and it really fascinated me, but try as I might I can't seem to find a book about it. I mean nothing! Are there any good ones out there you know of?

ISBN 096569920X
is the book you can buy at the house itself.

there are also three other titles
Captive of the Labyrinth: Sarah L. Winchester, Heiress to the Rifle Fortune
The Inscrutable Mrs. Winchester and Her Mysterious Mansion
and Sarah by Roger C. Rule

Penny,
Just to let you know I edited message 2 to add more info.

Ooh! Thanks!
