The Ghosts of Creepy Castle pg 1-2

From a pop up book published in 1994 in which the tourists progressively disappear page after page while our innocent guide never notices.

If you look, you'll notice the hand coming out of the water for the first victim!

Counting book (minus numbers...)?
Introduction to the macabre??
Who knows but I wish I had this when I was a kid.

Actually, almost wish I had kids at the time the book was published so I could have read it to them.
