Rook

Private detective Rook takes the cases nobody else wants: a vanished will, a neighbour who never makes a sound, an alibi that fits a little too well. Every story is a complete, self-contained mystery — read them in any order, each one solvable from the clues on the page.

Part 1 collects eight cases in clear B1 Dutch. Part 2, De Onthulling, raises the level to B2 with seven darker cases — and closes with the story that finally reveals who Rook really is. Both books include comprehension questions per story, a full answer key, and a glossary.
