Easton could discern a slight hump where the shape was its widest, and he swam there, hovering over it and fanning the sand with his hand. After five minutes, he had exposed a few inches of metal beam, fabric on one side. The bomb-bay door - it was partially a jar. He took out the Geiger counter and held it over the gap. Half the yellow LEDs came alive ... Beck Easton, software architect and secret member of a paramilitary wing of the National Security Agency, is ready to retire from his double life and move to Florida. But an unexpected project and a beautiful woman change his plans. It's a deceptively simple assignment: follow the trail of an Al-Qaeda operative. Beck traces a tangled thread of clues that interweave a top secret World War II mission, an ocean treasure, and a fanatic's plans that lead all the way to the World Trade Center in New York City. In this action-packed prequel to Deep Blue, author Tom Morrisey takes you deep into a world of espionage, ocean diving, and investigations into the events leading up to '9/11'.
