- 17 September 2026 — The archive’s visual clues are also accessibility clues
Maps, timelines and evidence diagrams now use written labels, borders and ordering—not colour alone—to carry meaning. Increased-contrast and forced-colour settings strengthen those distinctions automatically.
- 17 September 2026 — Craft and location audit
A new cross-file audit records composite filming places, architectural clue methods, the location status of all twelve episodes, live venue checks and recurring writing patterns with clear attribution boundaries.
- 17 September 2026 — Character dynamics and Cambridge travel
New ledgers record Lucy and John relationship changes without inventing private attitudes, and connect central Cambridge locations to current official rail, bus, walking and Park and Ride sources.
- 17 September 2026 — Research ledgers
New spoiler-light registers cover James-linked objects, places and communications; theory confidence; fair-play and viewer-solvability labels; specialist knowledge; deduction mistakes; a logic glossary; and John Taylor role changes.
- 17 September 2026 — Director approaches and production-made puzzle props
First-person interviews now identify Robert McKillop’s spatial-puzzle method and Jill Robertson’s three-dimensional planning, while credited production accounts confirm genuine working puzzle content made for on-screen props.
- 17 September 2026 — Series One DVD and Christmas-special forward watch
The UK Series One DVD release is now recorded with format, distributor, region, disc, running-time and subtitle details. A separate dated watchlist preserves six pre-broadcast questions for the Christmas special without presenting them as predictions.
- 17 September 2026 — Reader tools
Every file with reader tools now offers a page-specific correction link. Episode dossiers have a cleaner print layout, including visible link destinations.
- 17 September 2026 — Accessible reading
The theory board gains a plain-language explanation. The accessibility record now states the transcript policy for any future original audio or video.
