Joel tunes out.

Mr. Codpiece comes up behind him, lays a familiar hand on his shoulder. Joel resists the urge to shrug it off. That's another problem with these tour subs; no real cockpit, just a set of controls at the front end of the passenger lounge. You can't shut yourself away from the cargo.

"Quite a layout," Mr. Codpiece says.

Joel reminds himself of his professional duties, and smiles.

"Been doing this run for long?" The whitecap's skin glows with a golden tan of cultured xanthophylls. Joel's smile grows a little more brittle. He's heard all about the benefits, of course; UV protection, higher blood oxygen, more energy — they say it even cuts down on your food requirements, not that any of these people have to worry about grocery money. Still, it's too bloody freakish for Joel's tastes. Implants should be made out of meat, or at least plastic. If people were meant to photosynthesize they'd have leaves.

"I said—"

Joel nods. "Couple of years."

A grunt. "Didn't know Seabed Safaris was around that long."

"I don't work for Seabed Safaris," Joel says, as politely as possible. "I freelance." The whitecap probably doesn't know any better, comes from a generation when everyone pledged allegiance to the same master year after year. Nobody thought it was such a bad thing back then.

"Good for you." Mr. Codpiece gives him a fatherly pat on the shoulder.

Joel nudges the rudders a bit to port. They've been cruising just off the southeastern shoulder of the rift, floodlights doused; sonar shows a featureless landscape of mud and boulders. The rift itself is another five or ten minutes away. On the screen, the tourist program talks about giant squids attacking lifeboats during the Second World War, offers up a parade of archival photos as evidence; human legs, puckered with fist-sized conical wounds where horn-rimmed suckers cored out gobbets of flesh.

"Nasty. We going to be seeing any giant squids?"

Joel shakes his head. "Different tour."

The program launches into a litany of deepwater nasties; a piece of flesh washed up onto a Florida beach, hinting at the existence of octopus thirty meters across. Giant eel larvae. Hypothesized monsters that might once have fed on the great whales, anonymously dying out for lack of food.

Joel figures that ninety percent of this is bullshit, and the rest doesn't really count. Even giant squids don't go down into the really deep sea; hardly anything does. No food. Joel's been rooting around down here for years, and he's never seen any real monsters.

Except right here, of course. He touches a control; outside, a high-frequency speaker begins whining at the abyss.

"Hydrothermal vents bubble and boil along spreading zones in all of the world's oceans," the program chatters, "feeding crowds of giant clams and tubeworms over three meters long." Stock footage of a vent community. "And yet, even at the spreading zones, it is only the filter-feeders and muckrakers that become giants. The fish, vertebrates like ourselves, are few and far between— and only a few centimeters long." An eelpout wriggles feebly across the display, looking more like a dismembered finger than a fish.
