his wrist. âDiffusion normal-plus. No nitrogen.â
Back came Sparrowâs voice over the intercom: âLes, slide off.â
Ramsey felt the subtug lurch, then a faint whispering pulse of power. The deck assumed a slight upward incline, leveled. Presently, it tipped down.
Weâre headed into the deeps, thought Ramsey. Physically and mentally. From here on itâs up to me .
âMr. Ramsey, come to the control deck,â Sparrow ordered.
Ramsey closed down his board, went forward. Sparrow stood, hands behind his back, feet braced slightly apart almost precisely in the center of the control deck. He appeared framed in a background maze of pipes, wheels, levers, and dials. To his right, Garcia worked the tow controls; to his left, Bonnett held the high-speed pilot wheel. The big static pressure gauge high in the control bulkhead registered 1,310 pounds, increasing; they were below 3,000 feet.
Without turning, Sparrow asked, âWhatâs in that little box that came aboard with your effects, Mr. Ramsey?â
âMonitoring equipment for the new search system, sir.â
Sparrowâs head moved to follow the flickering of a towcontrol dial; he turned back. âWhy was it locked?â
âItâs extremely delicate and packed accordingly. They were afraid someoneââ
âIâll want to see it at the first opportunity,â said Sparrow. He stepped over behind Bonnett. âLes, is that a leak in compartment nine?â
âThereâs no moisture or pressure variant, Skipper. It has to be condensation.â
âKeep an eye on it.â Sparrow stepped back beside Ramsey.
Iâm going to find out quick if that disguise system in the box satisfies his curiosity , thought Ramsey.
âWhatâs your hobby?â he asked Ramsey.
Ramsey blinked. âAstronomy.â
Bonnett spoke over his shoulder: âThatâs a peculiar hobby for a submariner.â
Before Ramsey could reply, Sparrow said, âThereâs nothing wrong with astronomy for a man who goes to sea.â
âThe basis of navigation,â said Ramsey.
Sparrow glanced sidelong at Ramsey, returned his gaze to the board. âI was thinking as we moved out across the mooring basin back at base that we were entitled to a last look at the stars before going under the sea. They give one a sense of orientation. One night before we left Garden Glenn I was struck by the clarity of the sky. The constellation of Hercules wasââ He broke off as the Ram âs nose tipped upward.
A down hands moved over his controls to correct for the deflection.
âHercules,â said Ramsey. âDo you mean the Kneeler?â
âNot many call him that any more,â said Sparrow. âI like to think of him up there all these centuries, guiding mariners. The Phoenicians used to worship him, you know.â
Ramsey felt a sudden wave of personal liking for Sparrow. He fought it down. I must remain clearheaded and objective , he told himself.
Sparrow moved to the left to get a clearer view of the pilot gauges. He studied them a moment, turned to Ramsey. âHas it ever occurred to you, Mr. Ramsey, that these Hell Diver subtugs are the closest things to spaceships that mankind has developed? Weâre completely self-contained.â He turned back to the control board. âAnd what do we do with our spaceships? We use them to hide under the liquid curtain of our planet. We use them to kill one another.â
Ramsey thought: Hereâs a problem â a morbid imagination vocalized for the benefit of the crew. He said, âWe use them in self-defense.â
âMankind has no defense from himself,â said Sparrow.
Ramsey started to speak, stopped, thought: Thatâs a Jungian concept . No man is proof against himself. He looked at Sparrow with a new respect.
âOur underground base,â said Sparrow. âItâs like a womb. And the marine tunnel. A birth
