Part 7
Chapter 8 begins with an empty post-office box and time to fill. Claudia and Jamie stroll through New York, then buy tickets for a United Nations tour. When the ticket seller asks why they are not in school, Jamie produces an elaborate story about a broken boiler. Claudia admires how quickly he protects their cover. During the tour, she studies their Indian guide, especially her sari, graceful movement, and distinctive manner, and begins to think about what it means to be different. The next day, the museum’s reply is waiting. Its courteous tone cannot hide the disappointing conclusion: experts already know the mark, and it is not definite proof. Michelangelo might have designed the Angel while another person carved it, or a mark might be copied or counterfeit. Claudia cries, then refuses to let the setback decide who she will be. Instead of returning to Greenwich unchanged, she directs the quest toward Mrs. Basil E. Frankweiler in Farmington. Their final travel begins.

- Claudia redirects the journey toward Farmington.

- The museum’s polite reply explains why the mark is inconclusive.
- Jamie uses the boiler story before the United Nations tour.
Think back over the day the envelope came. The children did everything right — researched, observed, reported — and the answer still came back: we know, and it proves nothing. Jamie hears an ending; Claudia hears a redirection. She counts what is left — a little money, a lot of stubbornness, and one name from a newspaper — and aims the whole runaway at a stranger’s front door in Farmington.
Courts, laboratories, and museums all evaluate evidence, but they do not use one identical standard. A clue is an observation that supports an idea: a fingerprint, a test result, or a mason’s mark. Support is not certainty. Investigators ask whether a reasonable competing explanation still fits the same facts. A fingerprint proves little if ten people touched the glass; a mark proves little if a whole workshop used it. In museum attribution, unresolved alternatives call for a qualified label such as attributed to rather than a definite claim.
This discipline can frustrate an eager searcher. History is full of confident mistakes, paintings hung for decades under the wrong great name and medicines praised before adequate testing, that began with clues treated as certainty. In science, confidence grows when independent tests give repeatable results; in a court, legal standards determine how strongly evidence must support a decision. Museums compare style, materials, documents, and ownership history before naming a maker, while all three fields share one habit: conclusions should match the strength and limits of the evidence. Saying not established yet marks the current limit, and that disappointment can send a detective toward a stronger discovery.

Writing Task — Part 7 “Not Proven Yet”
Think of something you are almost sure about — a hunch about a friend, a theory about a game, a guess about how something works. Write about it like an honest investigator: your clue, the other explanations, and what evidence would settle it for good. Write at least 40 words.
No right or wrong — tell someone nearby what happened in this part. Can’t find anyone? Tell yourself out loud. The moment you teach it, you truly understand it.

The best last step is to teach it. In your own words, explain what happened — retell a favorite scene, teach a character’s big choice, or sum up the main idea for a parent, friend, or classmate. When you can teach it clearly, you truly own it.
