Castle Cary is a real town in Somerset, England. You can take the train there and step out on the same railroad platform where Meg, Will, and Ariel met Aunt Effie. But the resemblance ends there; I’ve created a fictional version of the town for this story. Castle Cary has been moved north and west, and I’ve generally rearranged things. If you visit, you will find a ruined castle and an old manor house in Castle Cary, but the manor is quite different from the one the Griffin children explore. As for the ghosts, you’ll have to see if you start hiccupping.
