The Devil’s Triangle by Catherine Coulter

FBI Special Agents Nicholas Drummond and Michaela Caine have a new mandate as the government’s Covert Eyes, assembling a handpicked team of top-notch agents to tackle crimes and criminals both international and deadly. But their first case threatens to tear the fledgling team apart when the enigmatic thief known as the Fox reappears with a plea for help.

Master thief Kitsune has stolen the staff of Moses from the Topkapi Museum in Istanbul, and now that she’s delivered, her clients are trying to kill her. On the run, she asks Nicholas and Mike to help her discover the true identity of her clients and stop the threat against her life. Under strict orders to arrest the Fox and bring her back to New York, the Covert Eyes team heads to Venice, Italy, to meet with Kitsune, and finds nothing is as it seems. Kitsune’s secret clients are the Koaths, a family descended from Moses himself, who will do anything, anything, to find the Ark of the Covenant and wield its power, as their long and bloody history can attest. To execute their plan, they’ve spent years perfecting a machine that can control the weather, manipulating worldwide disasters that spin the entire globe into chaos.

From New York to Venice, from Rome to the Bermuda Triangle, Nicholas and Mike and their team are in a race against time, and nature herself, to stop the Koaths and recover the famous Ark of the Covenant. But can they trust Kitsune, their sworn enemy, to help them save the world from a family of madmen?
