My free twelve-month cipher contest is now closed. I hope you enjoyed trying your hand at solving the secret messages!
If you didn’t get a chance to join in, the ciphers are all still available via the drop-down menu. Each historical cipher hides a passage from my (so far) unpublished novel, The Cause of These Disturbances. The solutions are also posted on each page, but if you’d like to try deciphering the passages yourself, you can use this handy workbook, which includes instructions for solving each cipher.
