As I started reading I saw similarities to Cold Comfort Farm. There’s no mad woman in the attic, but there is a father, a famous author, who has no idea what his three children are doing. There’s no income, the kids seem to be the adults while the famous author hides in his castle room. But then the new owner of the estate from whom the castle is rented comes from America, bringing romance to the teen-aged daughters. It’s an entertaining story, with opportunities for plenty of chuckles.
