Your aptitude test. Every puzzle is a pin in one great lock — solve the book and the final cipher becomes your acceptance into the Society.
Field training for the initiated. Harder locks, deeper secrets, and the craft of the keyhole laid bare.
A defector tried to crack the Society from the outside. This is the notebook they left behind — and the trail they hid inside it.
Volumes I and II stand open. Leave your address and we'll send word when new volumes, dispatches, and signals are ready to solve — nothing else.
Your request has reached the Society. When the first lock is ready, you'll be among the first invited through the door.
Five fragments. One code. It turns the final lock.
Recover all five, then enter the code at latch.works/keyhole.
