What this book practices

An original fair-play mystery set in a small-town museum. Every clue is on the page, so readers can solve it alongside Nell, and the "thief" turns out to be an honest mix-up. Practices noticing details, linking cause and effect, and waiting for the facts before blaming anyone.
