Plot summary
Around 900 BC, a Phoenician merchant ship sails to a remote and abandoned colony and conceals an unidentified treasure in a cave. On departing, they are approached by a more powerful Phoenician vessel. The first ship's captain, Menelik, meets on shore with the other ship's captain, his half-brother Melqart. Melqart ambushes Menelik and his men but they fend them off and destroy Melqart's ship.
In 1809, Thomas Jefferson prepares to return to Monticello at the end of his second term as president. A thief boards a river barge carrying his possessions with orders to destroy Jefferson's research on American Indian languages. However, some materials survive, including an unusual vellum with Phoenician writing Jefferson obtained from the Unkechaug tribe on Long Island. Jefferson believes the vellum reveals that the original tablets of the Ten Commandments were concealed in King Solomon's Mines in North America. Worried that the discovery will lead to unchecked westward expansion, he sends Louisiana Territory governor Merriwether Lewis a coded message concealed as an article about artichokes. Lewis dies under mysterious circumstances shortly after receiving the message.
Shortly after the U.S. invasion of Iraq, Italian-Ethiopian UNESCO investigator Carina Mechadi arrives at the Iraq Museum in Baghdad to investigate the looting of Iraqi antiquities in the chaos of the invasion. Senior curator Dr. Nasir tells her many items were looted by a group that had planned in advance to exploit the confusion. Dr. Mechadi meets with Iraqi antiquities smuggler Ali who she believes is responsible to seek the return of the items. After she leaves, professional assassin Adriano meets with Ali to discuss the purchase for businessman Viktor Baltazar of the Navigator, a bronze statue that shows an ancient Phoenician mariner using a compass. Ali tries to get more money from Adriano, who murders him to keep the statue from being sold to another buyer.
Baltazar anonymously provides Dr. Mechadi with unlimited funds for the recovery of Iraqi antiquities. Mechadi locates a cache of looted antiquities including the Navigator in Egypt. She purchases them with Baltazar's funds and places them on the container ship Ocean Adventure to the U.S. where she plans a museum tour to raise awareness on losses to Iraqi heritage. In the north Atlantic, Adriano and a party of mercenaries hijack the ship. After tying up Mechadi and the crew, they prepare to remove the Navigator by helicopter and set the ship's autopilot on a collision course with a nearby oil rig to eliminate evidence of their attack and kill witnesses. A Canadian International Ice Patrol ship picks up a distress call from the oil rig. National Underwater and Marine Agency employees Kurt Austin and Joe Zavala, who had been on the ice patrol ship to learn about iceberg wrangling, intervene. With Zavala's aid, Austin boards the container ship from a small boat, frees Mechadi and the crew, and prevents the hijackers from taking the Navigator although they are able to escape. The ship's captain regains control of his vessel and narrowly avoids a collision with the oil rig. Austin and Zavala borrow a helicopter from the oil rig to pursue the hijackers and locate the ore carrier Sea King that has been modified by mercenary company PeaceCo to launch helicopters.
At the American Philosophical Society in Philadelphia, assistant librarian Angela Worth helps writer Norman Stocker research a book on artichokes. Stocker finds Jefferson's message to Lewis, misfiled due to its appearance as a simple message about artichokes. Stocker shows the material to Worth, who identifies it as an encoded message from Jefferson. Worth brings the Jefferson file to her boss Helen Woolsey, who claims she will investigate it. However, Woolsey is paid by Baltazar to suppress any material found on the subject. She reports the findings to Baltazar while Worth investigates on her own. Worth, an amateur cryptographer, meets with a friend at the National Cryptologic Museum. With the aid of Professor Pieter DeVries at the National Security Agency, they break the cipher. DeVries brings the decrypted message to the Bureau of Near Eastern Affairs of the U.S. State Department. Devries and State Department staffer Hank Douglas agree that the discovery may destabilize the Middle East, especially if it leads to Israel deciding to build a Third Temple on the Temple Mount in Jerusalem, a site contested by Muslims and Jews.
