In 1969, en route for a summer holiday in the Cévennes, I made the casual purchase of a paperback. Le Trésor Maudit by Gérard de Sède was a mystery story-a lightweight, entertaining blend of historical fact, genuine mystery, and conjecture. It might have remained consigned to the postholiday oblivion of all such reading had I not stumbled upon a curious and glaring omission in its pages.

The "accursed treasure" of the title had apparently been found in the 1890s by a village priest through the decipherment of certain cryptic documents unearthed in his church. Although the purported texts of two of these documents were reproduced, the "secret messages" said to be encoded within them were not. The implication was that the deciphered messages had again been lost. And yet, as I found, a cursory study of the documents reproduced in the book reveals at least one concealed message.
