Tom Arden, who found a long lost Rembrandt (Rembrandt Redux), is now an assistant curator with the Metropolitan Museum of Art in New York. He's intrigued by an embroidered cloth painted in a 16th century still life by a Dutch Master.
In the process of interpreting a partial message, he becomes convinced that the cloth is the one mentioned in a legend involving Leonardo da Vinci.

A zealot, whose purpose in life is to guard critical secrets on behalf of a future Ottoman Empire, will stop at nothing to prevent a powerful revelation on the cloth. A murder prompts Tom to pursue a suspect, and a confrontation ensues amidst Roman ruins in Cyprus. Determined to retrieve the cloth and the entire message, Tom battles the zealot only to find a secret treasure that harbors a mystery.
