The Temple Keep

Dig Into the Codes, Crypts, and an Explosive Secret That Will Forever Change History

Beneath the storied campus of one of America’s oldest universities, something impossible is hidden.

When Noah Greaves—an outsider with a gift for math and a taste for the obscure—unlocks a strange cipher buried in a Shakespearean sonnet, he stumbles into a centuries-old underground crusade where scholars, spies, mystics, and cryptographers hunt the same thing: a vault built in shadows, rumored to contain something far greater than gold.

Based on actual places and events–from colonial-era crypts to forgotten tunnels, from lost Masonic blueprints to encoded poetry, “The Temple Keep” weaves history, architecture, literature, mathematics, and physics into a gripping race to solve the ultimate riddle of human existence—one hidden in plain sight, and protected by blood.

Atmospheric, erudite, and deeply unsettling, “The Temple Keep” is a mind-bending thriller for readers who believe that some truths are written in stone—and others, in code.

A Mysterious Map

Visit Colonial Williamsburg and be sure to bring a copy of the mysterious piece of cartography known as “The Frenchman”s Map.” Did Thomas Jefferson himself have a hand in its design? Do the scribbles in the margins–long dismissed his historians as “graffiti”–actually involve sacred geometry that links Williamsburg to another revolutionary city? Bonus: Note the clear symbol of Freemasonry–the compass and the square–encompassing the entire old campus of The College of William and Mary.

Decode the Cipher

Sir Francis Bacon developed an ingenious “bi-literal” cipher, in which “anything could be made to say anything.” Were the works of Shakespeare embedded with such code? Use Bacon’s cipher key to create a code of your own. Bonus: “The Temple Keep” has bi-literal code embedded in it. Can you break it?”
