Miss Kavalier was almost thirty when she married. She was four inches shorter than her diminutive husband, sinewy, grim-jawed, her eyes the pale gray of rainwater pooled in a dish left on the window ledge. She wore her black hair pulled into an unrelenting bun. It was impossible for Sammy to imagine his mother as she must have been that summer of 1919, an aging girl upended and borne aloft on a sudden erotic gust, transfixed by the vein-rippled arms of the jaunty homunculus who carried winking hundred-pound blocks of ice into the gloom of her cousin Lev Kurtzburg's saloon on Ludlow Street. Not that Ethel was unfeeling-on the contrary; she could be, in her way, a passionate woman subject to transports of maudlin nostalgia, easily outraged, sunk by bad news, hard luck, or doctor's bills into deep, black crevasses of despair.

"Take me with you," Sammy said to his father one evening after dinner, as they were strolling down Pitkin Avenue, on their way out to New Lots or Canarsie or wherever the Molecule's vagabond urges inclined him that night. Like a horse, Sammy had noticed, the Molecule almost never sat down. He cased any room he entered, pacing first up and down, then back and forth, checking behind the curtains, probing the corners with his gaze or the toe of a shoe, testing out the cushions in the chair or sofa with a measured bounce, then springing back onto his feet. If compelled to stand in one place for any reason, he would rock back and forth like someone who needed to urinate, worrying the dimes in his pocket. He never slept more than four hours a night, and even then, according to Sammy's mother, with inquietude, thrashing and gasping and crying out in his sleep. And he seemed incapable of staying in any one place for longer than an hour or two at a time. Though it enraged and humiliated him, the process of looking for work, crisscrossing lower Manhattan and Times Square, haunting the offices of booking agents and circuit managers, suited him well enough. On the days when he stayed in Brooklyn and hung around the apartment, he drove everyone else to distraction with his pacing and rocking and hourly trips to the store for cigars, pens, a Racing Form, half a roast chicken-anything. In the course of their post-prandial wanderings, father and son ranged far and sat little. They explored the eastern boroughs as far as Kew Gardens and East New York. They took the ferry from the Bush Terminal out to Staten Island, where they hiked out of St. George to Todt Hill, returning well after midnight. When, rarely, they hopped a trolley or caught a train, they would stand, even if the car was empty; on the Staten Island Ferry, the Molecule prowled the decks like a character out of Conrad, uneasily watching the horizon. From time to time in the course of a walk, they might pause in a cigar shop or at a drugstore, where the Molecule would order a celery tonic for himself and a glass of milk for the boy and, disdaining the chrome stool with its Naugahyde seat, would down his Cel-Ray standing up. And once, on Flatbush Avenue, they had gone into a movie theater where The Lives of a Bengal Lancer was playing, but they stayed only for the newsreel before heading back out to the street. The only directions the Molecule disliked to venture were to Coney Island, in whose most evil sideshows he had long ago suffered unspecified torments, and to Manhattan. He had his fill of it during the day, he said, and what was more, the presence on that island of the Palace Theatre, the pinnacle and holy shrine of Vaudeville, was viewed as a reproach by the touchy and grudge-cherishing Molecule, who never had, and never would, tread its storied boards.

"You can't leave me with her. It isn't healthy for a boy my age to be with a woman like that."

The Molecule stopped and turned to face his son. He was dressed, as always, in one of the three black suits that he owned, pressed and shiny with wear at the elbows. Though, like the others, it had been tailored to fit him, it nonetheless strained to encompass his physique. His back and shoulders were as broad as the grille of a truck, his arms as thick as the thighs of an ordinary man, and his thighs, when pressed together, rivaled his chest in girth. His waist looked oddly fragile, like the throat of an egg timer. He wore his hair cropped close and an anachronistic handlebar mustache. In his publicity photographs, where he often posed shirtless or in a skintight leotard, he appeared smooth as a polished ingot, but in street clothes he had an unwieldy, comical air and, with the dark hair poking out at his cuffs and collar, he looked like nothing so much as a pants-wearing ape, in a cartoon satirizing some all too human vanity.

"Listen to me, Sam." The Molecule seemed taken aback by his son's request, almost as though it dovetailed with his own thinking or, the thought crossed Sammy's mind, he had been caught on the verge of skipping town. "Nothing makes me happier than I take you with me," he continued, with the maddening vagueness his ill grammar permitted. He smoothed Sammy's hair back with a heavy palm. "But then again, Jesus, what a crazy fucking idea."

Sammy started to argue, but his father raised a hand. There was more to be said, and in the balance of his speech Sammy sensed or imagined a faint glimmer of hope. He knew that he had chosen a particularly auspicious night to make his plea. That afternoon, his parents had quarreled over dinner-literally. Ethel scorned the Molecule's dietary regimen, claiming not only that the eating of raw vegetables had none of the positive effects her husband attributed to it but also that, every chance the man got, he was sneaking off around the corner to dine in secret on steak and veal chops and french-fried potatoes. That afternoon, Sammy's father had returned to the apartment on Sackman Street (this was in the days before the move to Flatbush) from his afternoon of job hunting with a bag full of Italian squash. He dumped them out with a wink and a grin onto the kitchen table, like a haul of stolen goods. Sammy had never seen anything like these vegetables. They were cool and smooth and rubbed against one another with a rubbery squeak. You could see right where they had been cut from the vine. Their sliced-off stems, woody and hexagonal, implied a leafy green tangle that seemed to fill the kitchen along with their faint scent of dirt. The Molecule snapped one of the squashes in two and held its bright pale flesh up to Sammy's nose. Then he popped one in his mouth and crunched it, smiling and winking at Sammy as he chewed.

"Good for your legs," he had said, walking out of the kitchen to shower away the failures of the day.

Sammy's mother boiled the squash until it was a mass of gray strings.

When the Molecule saw what she had done, there were sharp and bitter words. Then the Molecule had grabbed brusquely for his son, like a man reaching for his hat, and dragged Sammy out of the house and into the heat of the evening. They had been walking since six. The sun had long since gone down, and the sky to the west was a hazy moire of purple and orange and pale gray-blue. They were walking along Avenue Z, dangerously close to the forbidden precincts of the Molecule's early sideshow disasters.

"I don't think you got the picture what's it like out there for me," he said as they walked along. "You think it's like a circus in the pictures. All the clowns and the dwarf and the fat lady sitting around a nice big fire eating goulash and singing songs with an accordion."

"I don't think that," Sammy said, though there was stunning accuracy in this assessment.

"If I did to take you with me-and I am just saying now if-you will have to work very hard," the Molecule said. "They will only accept you if you can work."

"I can work," Sammy said, holding out an arm toward his father. "Look at that."

"Yeh," the Molecule said. He felt very carefully up and down the stout arms of his son, very much in the way Sammy had fingered the zucchini squash that afternoon. "You have arms that are not bad. But your legs are not so good."
