Ears underwater, she could hear the ripples of noise, the subtle pings and gurgles of passing creatures. She knew some of their names, some family lineages. There was also a deeper sound, a nearly mystical hum in the bay that vibrated far below the surface, a quiet throb of power that somehow fed her, renewed her strength on these nightly swims. She'd dared to reveal this to her granddaughter some months back, calling it a "soft drumroll of energy," and the girl, a modern woman, skeptical and tough-minded, had fired back that Marion was probably only hearing the chug of sewage as it pumped from the city's vast network of toilets and drainpipes beneath the bay across to Virginia Key.

The slack hour passed without event, and Marion sculled the water, readjusted her body into a fast-moving channel so she could begin her return voyage. As she glided back toward the shore she was joined, as she so often was, by Booger.

Tonight Booger pressed close to her, scraped her arm with one of his barnacles, drew blood. Her skin was papery these days, easily torn. They glided along together, soundless, and the fleshy sea cow continued to bump her, continued to urge her forward with something like impatience. Marion did not resist. Long ago she'd abandoned the need for overmanaging her destiny.

There was nothing she absolutely needed to do anymore. She had won her prizes, taken her bows, had shaken the hands of a half-dozen presidents. Now her most reliable pleasures came from these nightly rides, from giving herself over to the vagaries of the natural world. So she let Booger speed her along to the shallows just off her beach. It was there that she had made a habit of grooming Booger, clearing him of the flotsam and jetsam that he regularly snagged in his journeys around the bay.

She let her legs dangle down, caught the bottom, then trudged up to the shore, shedding water like sparkling confetti. Booger bobbed nearby, his skin silvered by the moon. Tonight he was even more of a mess than usual. He looked like a honeymoon car with strings of tin cans dragging behind him. Fishing line was wrapped around his fins, twigs and broken driftwood trapped in the line. There were two plastic six-pack holders caught on a notch near his back flipper, and knotted to them was a mooring line that trailed off behind him for twenty feet.

Marion dragged the line hand over hand, hauling the heavy mass across the soft bay bottom. It was a wonder that Booger had been able to swim at all so entangled in trash. She hauled it out of the water and held it up to the soft moonlight. Splintered wood and elastic cords and another nest of snarled fishing line that ensnared a silver canister.

Marion patted Booger, told him to wait, then walked up the shore to her chikee hut, where she kept a razor-edged fillet knife for just such tasks as this. She came back to Booger, cut him free of his clutter of trash, gave him a stroke along his broad slick forehead, and watched him turn and wrallow away into the night.

Hector and Phil took Fay to their hideout. Actually, it was an efficiency apartment off Tigertail Avenue in the Grove. But Hector liked calling it their hideout even though they hadn't had to hide out in it yet, 'cause they hadn't succeeded in doing anything bad enough to be pursued.

Hector had found the apartment, liked the view of the pool, and given the manager first and last month's rent on the spot. Then he'd found he couldn't afford it, and asked Phil if he wanted to share the rent. Phil, recently split from his wife, had said sure. So they'd laid out two pool floats on the middle of the living room floor, the red one for Hector, the blue one for Phil, and called it home. Fine by Hector. Pool floats were better beds than he'd had at the Dade County Jail or Raiford. Better than when he was growing up in Havana, sleeping on the mud floor of the little barn. A goat for a roommate, chickens for companions.

This apartment was a perfect spot for spying on the babes who used the pool. Lots of them, secretaries mainly, a couple he'd gotten to know lately. Or at least he'd said a couple of words to them and given them a tongue flick. That tongue flick almost always worked on the average woman. But no luck so far with the fussy secretaries.

"Hey, man," Hector said. "I got an idea what we can do with this pretty lady she doesn't tell us what she knows."

Phil was sitting up on the kitchen counter, legs dangling. They didn't have furniture yet, so counter-sitting was about it for taking a load off your feet, except for the floats, and you couldn't use them too much or they'd spring more leaks.

Phil was staring at Fay, a weird look in his eyes. Fay was dressed in the yellow plastic foul-weather gear they'd found on the Whaler. Looking cute. Pouty lips, with some bite in her green eyes.

Hector liked women with sharp teeth, women who liked to bite. He liked teeth marks on his shoulders. He liked giving them back, a nice oval bruise on their inner thighs. Yeah. Hector had a way with women.

Phil told Hector to stop looking at Fay that way. And Hector said a very bad thing to Phil. Phil said a very bad thing back to Hector. Hector said two very bad things. And Phil replied with three very bad things.

"Knock it off," Fay said. She stalked around, staring at each of them. Hector smiling at her, trying to decide where he wanted to plant his first teeth marks.

"Now," Fay said. "Which of you idiots is going to tell me what this is all about?"

"You tell us, pussy boots," Hector said. "That's what you here for. You here to tell us whatever we ask you." Phil said a very bad thing. And Hector replied in kind.

"OK, dammit, what's going on, Phil?" Fay said. "What the hell are you doing hanging out with this creep?"

Hector spun around. "Hey, man. How come she know your name, Phil? She said your name, man. How she know that? You tell her your name, you stupid moron breath?"

Phil said a very bad thing.

Fay said, "I asked you a question, Phil."

"So did I, Phil. How she know your name, man? You know this broad?"

"She's my wife," Phil said.

Under his breath Hector said a very bad thing. Then he said three very bad things out loud.

"Ex-wife," Fay said. "Ex, Phil, ex. And this is why. This, right here, what's going on this very minute, this is exactly why you don't live at home anymore. This is why it's finished."

Marion lugged the silver canister up to her house. She laid it on the glider on her front porch and went inside to shower and dress. Her windows were all open and the first cool breezes of the new season were sighing through them tonight. She dressed in long khaki pants and a plaid flannel shirt. She put on her brogans and rubbed some lavender-scented face cream into the grooves that lined her cheeks. She put a Band-Aid on the cut that Booger had given her.

She went back down to the porch and sat down in a wicker rocker across from the glider. Something had shifted inside her. She had felt it happen earlier. Some tectonic realignment that was sending tremors up to her flesh. She quivered with excitement for the first time in decades.

Quivering was dangerous at her age. But quiver she did. She had something in her possession that was worth something to the world at large. She sensed it. She knew that the placid young man she had pulled from the bay and nursed with Sawgrass Juice had found a similar canister and was queerly excited by its existence.

She was not sure what it meant. Canisters washing ashore? Perhaps hundreds or even thousands of silver containers drifting along the bottom of the bay. She knew she was onto something. Something of major proportions. A shipwreck out in the Gulf Stream, the canisters just now working their way to shore? Some high-tech note in a bottle thrown out from a passing spaceship? This was something new. Rejuvenating. Something that might just rescue her from the doldrums of old age.
