With the lowered sail facing one shore and his back to the opposite, he leaned over the side and peered into a bucket with a transparent bottom. The water was so crystal clear that Pitt could see a school of salmon swimming a good hundred and fifty feet below. Then he opened a fishing tackle box and removed a hook and lead sinkers. The only fish Pitt had caught in the past thirty years, he caught underwater with a spear gun. He hadn't held a rod and reel in his hands since he fished with his father, Senator George Pitt, off the coast of California when he was a young boy. Still, he managed to tie on lead sinkers, slip an unfortunate night crawler over a hook and cast it into the deep.

While under the pretense of fishing, he also uncoiled a reel of thin wire and placed a coffee cup-sized transponder that sent and received electronic signals over the side of the sailboat. He lowered it to a depth of twenty feet to assure that it was out of the acoustic shadow of the boat's hull. A similarly sized transponder was housed in the aft end of the AUV. These two units and the electronics inside the AUV casing formed the heart of the system by talking to each other acoustically, allowing underwater control and video signals to be received by a small recorder.

Next, he removed the AUV from the ice chest, carefully lowered it into the water and watched as it silently slipped beneath the surface, its black casing giving the appearance of some ugly creature from the abyss. Pitt had over two hundred hours operating tethered robotic underwater vehicles, but this was only the second time he had operated an autonomous system. His mouth felt slightly on the dry side as he watched the little vehicle that had cost NUMA two million dollars sink out of sight into the lake. The autonomous underwater system was a marvel of miniaturization and for the first time enabled NUMA scientists to send a robotic unit into areas that were previously impossible to reach.

He unfolded a laptop computer with an oversized, high-resolution, active-matrix display, and powered up the system. Satisfied a secure acoustic link was established, he scrolled through the control menus and selected a combination of "remote and live video." Under normal circumstances he would have preferred to concentrate on a live video display of the images recorded by the camera under the water, but this trip it was vital that he focus his attention on the events that he hoped to incite at the retreat. He intended only to view the progress of the AUV from time to time to keep it on course.

He moved the joystick on a small remote handbox. The vehicle immediately responded and went into a dive. The acoustic telemetry and control system performed flawlessly, and the vehicle shot forward at almost four knots. The counter rotating thrusters were balanced perfectly, preventing the vehicle from corkscrewing through the water.
