"This isn't the same thing that got Gene," he buzzes. "Different teeth. Gigantism in at least two different species of bony fish, within two kilometers of a hydrothermal vent." He reaches into the gaping maw, snaps off a tooth. "Osteoporosis, probably other deficiency diseases as well."

"Maybe you could save the lecture until you straighten that out for me?" She points to where her squid, listing drunkenly, describes small erratic circles in the overhead darkness. "I don't think I'm gonna be swimming home with this leg."

He coasts up and wrests the vehicle back under control. "We have to bring it back," he says, riding it down to her. "All of it," with a nod to Lopez's gutted remains.

"It's not necessarily what you think," she tells him.

He turns and jackknifes into Impossible Lake, on the trail of his own squid. Clarke watches his rippling image kicking hard, fighting against buoyancy.

"It's not ßehemoth," she buzzes softly. "It'd never survive the trip." Her voice is as calm as such mechanical caricatures can be out here. Her words sound reasonable. Her thoughts are neither. Her thoughts are caught in a loop, a mantra borne of some forlorn subconscious hope that endless repetition might give substance to wishes:

It can't be it can't be it can't be…

Here on the sunless slopes of the Mid Atlantic Ridge, facing consequences that have somehow chased her to the very bottom of the world, denial seems the only available option.

Portrait of the Sadist as a Young Boy

Achilles Desjardins wasn't always the most powerful man in North America; at one time he'd been just another kid growing up in the shadow of Mont St-Hilaire. He had always been an empiricist though, an experimenter at heart for as long as he could remember. His first encounter with a research-ethics committee had occurred when he was only eight.

That particular experiment had involved aerobraking. His parents, in a well-intentioned effort to interest him in the classics, had introduced him to The Revenge of Mary Poppins. The story itself was pretty stupid, but Achilles liked the way the Persinger Box had slipped the butterfly-inducing sensation of flight directly into his brain. Mary Poppins had this nanotech umbrella, see, and she could jump right off the top of the CN Tower and float to earth as gently as a dandelion seed.

The illusion was so convincing that Achilles' eight-year-old brain couldn't see why it wouldn't work in real life.

His family was rich—all Quebecois families were, thanks to Hudson Hydro—so Achilles lived in a real house, a single stand-alone dwelling with a yard and everything. He grabbed an umbrella from the closet, let it bloom, and—clutching tightly with both hands—jumped off the front porch. The drop was only a meter and a half, but that was enough; he could feel the umbrella grabbing at the air above him, slowing his descent.
