Everything the Society has put into print. Buy on Etsy where you can leave a review that helps the next reader find us; paperbacks come from Amazon where noted. Every one is machine-proven solvable — the Puzzlexity Verified promise.
One great lock, twenty-four chained transmissions, and hidden layers beneath. Start here.
The aptitude test — solve the book and the final cipher becomes your acceptance.
Field training for the initiated: harder locks, deeper secrets.
One evening each, a fresh visual cipher every time — and they chain into a hidden meta.
A keeper's light on a drowned coast; a cipher held in the tides.
Wartime intercepts and a code buried in the static.
A sleeper car, a vanished passenger, a cipher on the rails.
Star-charts and a code written in the constellations.
The first three hunts together, at a keeper's discount.
Teaching micro-books — each drills a single concealment hand, with hidden puzzles baked in.
The comparator hand: a mark tells you which neighbour to take.
The grid-hand: an address points into a page's own words.
