Duke runs the engineering office from his throne in the center of the room. One wall is covered in instruments; the other is a long stretch of windows overlooking the moon pool at the heart of the ship. A door at one side of the window wall provides access to a steel-mesh catwalk fifty feet above the pool.

Here in the office the noise of the hydraulic stabilizers isn't quite deafening; there's a loud mechanical whine and a vibration they feel through the soles of their boots, but the skull-rattling throbbing is damped to a survivable level. The drilling tower above their heads lowers the endless string of pipes into the center of the pool at a steady six feet per minute, day in and day out. Steve tries not to look out the window at the pipes because the effect is hypnotic: they've been sliding smoothly into the depths for many hours now, lowering the grab toward the bottom of the ocean.

The ship is much bigger than the grab that dangles beneath it on the end of three miles of steel pipe, but it's at the grab's mercy. Three miles of pipe makes for a prodigious pendulum, and as the grab sinks slowly through the deepocean currents, the ship has to maneuver frantically to stay on top of it in the six-foot swells. Exotic domes on top of the vessel's bridge suck down transmissions from the Navy's Transit positioning satellites, feeding them to the automatic Station Keeping System that controls the ship's bow and stern thrusters, and the cylindrical surge compensators that the derrick rests on. Like a swan, it looks peaceful on the surface but under the waterline there's a hive of frantic activity.

Everything — the entire 400-megabuck investment, ten years of Company black operations — depends on what happens in the next few hours. When they reach the bottom.

Steve turns back to his TV screen. It's another miracle of technology. The barge has cameras and floodlights, vacuum tubes designed to function in the abyssal depths. But his camera is flaking out, static hash marching up the screen in periodic waves: the pressure, tons per square inch, is damaging the waterproof cables that carry power and signal. "This is shit," he complains. "We're never going to spot it — if..."
