Episode verification queue
All six Series 2 episodes have completed their BBC One run. Episodes 4–6 still need independent programme, clue-log and solution-chain checks before their dossiers can move beyond the current evidence boundary.

What the archive still needs
Publishing gaps makes the Casebook easier to correct and prevents an unfinished inference being mistaken for fact.
Scene and credit evidence
Episodes 4–6 still need published-source scene details, end-credit checks and scene-level evidence logs. Several building-level location matches also remain secondary and are labelled accordingly.
not yet recorded permission
Official episode stills and publicity portraits are not reproduced until a rights-holder supplies explicit terms.
