Casefile Archives is a series of special bonus releases revisiting the earliest years of the show. The re-run episodes have been completely edited, polished, re-recorded and freshly produced from start to finish to match our current production standards. They are not complete rewrites - our goal wasn’t to alter the cases or reshape the writing, but to preserve the original storytelling while giving the production the refinement it didn’t have when we started the show back in 2016.

Where appropriate, updates have been added, but the core structure and storytelling remain faithful to the originals. Because of this, these re-releases may sound a little different to our recent episodes, but they allow us to bring some of the earliest episodes up to the technical quality listeners expect today.
