The Midnight Duel

Did you notice?

A dare, a lost passage, and a detention that is worse than a duel would have been. Rule-breaking is the plot engine, and the book is honest that it is also how you stumble into the forest. A three-headed dog is a locked door with teeth. Nobody sensible leaves that alone.

Foreshadowing

The trapdoor puzzle is the year’s true syllabus: obstacles that are really a staff security system. The same pattern — student trespass uncovering adult precautions — repeats every book, with higher costs.

This echo points at book 2. It is a reading note, not a quote.
