About Penn Leary

The. Complete. Cryptographic. Shake-speare.

From a trip to Nova Scotia in search of buried treasure to a groundbreaking discovery calling into question the authorship of Shakespeare's works, Penn Leary explores the connection between Francis Bacon and William Shakespeare through cryptography and ciphers of the Elizabethan period. As Leary demonstrates, the Caesar cipher system is key to revealing that Francis Bacon was the true author of the Shakespearean works.

The Oak
Island Enigma

In a gripping history of Oak Island and its mysterious "Money Pit," Penn Leary details the island's intriguing secrets: the shaft with its many platforms, the strategic drainage tunnels that flood the pit with sea water, and the many attempts to uncover what the construction hides and protects.

Originally published in 1953, The Oak Island Enigma was the first book to suggest that the manuscripts of William Shakespeare's works, actually written by Sir Francis Bacon, may be buried beneath Oak Island.
