In 1981, Carole Marsh (a real writer) took four real kids on a visit to the famous Biltmore House in Asheville, North Carolina. They went to learn about George W. Vanderbilt, the Victorian Era, O. Henry, and more. There was only one little problem... First one kid disappeared. Then another! Then, so did a priceless antique chess set! There was the creepy Halloween room, the very scary basement, the eerie attic, and all those gape-mouthed gargoyles. Oh yeah, and all that blood! And did I say that the kids got trapped in the mile-long heating system? Did I say ONE LITTLE problem?! How about LOTS of BIG problems!
