Clarissa tried to be elder-sisterly. "We can't go sneaking out of the hotel at half-past eleven at night. Aunt Maddy wouldn't like it."
"What the eye doesn't see the heart doesn't grieve over," said Thomas. "It's a bit of luck, really, Uncle James getting malaria."
We all shrieked at Thomas for such a selfish attitude, but of course the awful thing was that he was right, in a way; we certainly would be more free to come and go without Aunt Maddy's eagle eye on us."
