Every Archive comes with homework. The fun kind.
Before your Bridgewater file arrives, or after you have torn it open, here is what to listen to. Every episode plays right here on the site.
The Listening List: Archive 002
Sinisterhood, Episode 316: The Bridgewater Triangle
A stretch of southeastern Massachusetts where everything happens at once: ghost lights, black dogs, giant birds, and things with no name. The perfect primer before you read the case file.
Bring a pencil
Your Bridgewater file is interactive. Hidden inside is a coded transmission and a Field Kit that walks you through cracking it by hand: find five clues in the story, build the cipher key, and decode the message. No app, no screen, just you and a pencil. Solve it and you earn Fragment 02 of the Season Cipher, the second of twelve pieces that spell your Keeper's Passphrase.
Missed a fragment?
Joined partway through the season? The Keeper's Key is a printable dossier with every fragment released so far, so you can fill in your tracker and keep up. Annual members get it free in their first envelope.
Been to the swamp? Seen a light that should not be there?
Members can go on record. Send your theories and stories to the Archive and the best ones get credited in future files.
