Logan filled her in as he donned his equipment. He strapped on a weight belt and squeezed his feet into fins. A knife in a sheath was tied to his calf and from the weight belt he slung a waterproof torch. Gus handed him a mask; not an ordinary dive mask, but one that was a full-face glass plate with a tiny radio transmitter embedded in the plastic just below where the diver's mouth would be. The face plate was attached to a waterproof rubber hood with small earphones on either side. Extending five centimetres from the top of the face plate was a waterproofed aerial. Logan attached a specially designed regulator hose to a scuba tank, then screwed the other end to a valve on the bottom of the face plate. He slipped into the communications mask, tested the air intake, then the communications.

Gus was holding a transmitter receiving unit, not unlike a walkie-talkie. He spoke into it. "You're coming through loud and clear."

"So are you," replied Logan.

"You all set?"

Logan nodded. He climbed over the transom and down a short ladder to a diving platform. Stenciled on the stern of the boat in bright blue lettering was her name: SEA WASP. Logan stood on the platform a moment and adjusted his air tank's harness straps. Then he turned, gave Gus the okay signal and dropped feet first into the sea.

Gus quickly returned to the interior bridge to monitor things on the scanner. Sheridan trailed him inside.

Three metres below the surface, Logan waited for his entry bubbles to dissipate. When they had he performed a slow pirouette to take stock of his surrounds and make certain no predators were lurking nearby. He saw nothing but water, not even a fish.
