The speakeasy beneath the nightclub on State Street smelled of gin and danger and the particular kind of optimism that flourishes when prohibition makes contraband more profitable than wheat. Tommy Callahan sat at the bar when the phone rang. It was a Wednesday. It was always a Wednesday when the phone rang, because that was the day his daughter called. Not every Wednesday. Every other Wednesday, sometimes. She lived in Miami now, where the sun made everyone look healthy and no one looked trustworthy, and he lived above a bottling operation in Chicago and the distance between them was measured in phone bills and broken promises and the kind of love that persists despite itself.

"Hey, Pop." "Hey, Maggie." "You doing okay?" "Yeah. You?" "Good. How's the—how's the operation?" He glanced toward the back room. The operation was there. It was the same as it had been yesterday. It would be the same tomorrow. It was always almost working. Almost. "The operation's fine," he said. "You sound exhausted." "I'm fine." There was a pause. The kind of pause that exists between two people who care about each other profoundly but have run out of things to discuss that do not involve money or health or the weather. "I'm coming back in December," Maggie said. "For Christmas." "Alright." "Love you, Dad." "Love you too, kiddo." He replaced the receiver. He sat on the barstool for ten minutes, listening to the jazz band tune up in the main room. Then he walked to the back.

The back room was twelve feet by eighteen feet and contained equipment that Tommy had accumulated over fifteen years in the bootlegging business. A copper distilling column that he had built himself from scavenged parts. A row of fifty-gallon drums painted black to conceal their contents. A refrigeration unit salvaged from a deceased salesman's refrigerator that kept the product cold enough to satisfy the most demanding clientele from Lakeview to Hyde Park. The operation sat on a steel table in the center of the room, taking up roughly four feet of surface space. It was constructed from copper tubing, glass condensers, brass fittings, and rubber hose, pieces acquired from salvage yards, sympathetic hardware store owners, and the occasional black market dealer who knew a good price when he saw one.

To an outsider, it looked like plumbing equipment arranged by someone who had given up on plumbing. To a bootlegger, it looked like the kind of apparatus that could turn molasses into money with sufficient patience and a network of connections that extended from the South Side to the Gold Coast. To Tommy, it looked like the thing that was always one adjustment away from perfect efficiency.

Tommy adjusted a valve. He checked the temperature. He adjusted the valve again. The alcohol content reading on the hydrometer was 94 percent. He wanted 95. One percent. That was the difference between product that moved quickly and product that moved quickly enough. He tightened a fitting. He checked again. 94 percent. He loosened it slightly. He checked. 94.2 percent. Almost.

Tommy had worked at the Studebaker plant for twelve years before he turned to more profitable enterprises. He had started in 1920, straight out of the war, on the assembly line at the South Side facility. He did not build entire automobiles. He installed hubcaps. Not entire wheels—hubcaps, specifically. The round metal covers that went over the lug nuts, the things that flies off on the highway and takes out a mailman's window and costs forty dollars to replace in an era when forty dollars could buy a week's groceries for a family of five.

He installed hubcaps for forty minutes, took a ten-minute break, installed hubcaps for forty minutes, took another break, and repeated this cycle ten times a day, six days a week, for twelve years. He was good at it. He was the fastest hubcap installer on his floor. His foreman, a Italian-American veteran named Russo who had been installing hubcaps for twenty years and whose son was currently learning the same motion, once told him: "Callahan, you're the only guy on this line who makes me uncomfortable. You treat a hubcap like it's the crown jewel of the British monarchy."

Tommy did not care about hubcaps. He cared about the feeling of a hubcap installed properly—the satisfying snap when the retainer clip engaged, the way it spun smoothly without wobbling at sixty miles per hour, the way it caught the sunlight and flashed silver when a car passed you on the expressway and you wanted that flash to say something about quality even if the engine inside the fender was falling apart.

When Studebaker restructured in 1932 and eliminated his position, Tommy stood in the parking lot for twenty minutes after everyone else had driven away, looking at the car he had almost bought with his severance pay, and then he went home, borrowed money from a man named Moretti who lent money at twenty percent weekly interest, and started his own operation.

The envelope on the steel table, under the glass paperweight, was a notice from the Internal Revenue Service. It had been there for two years. Tommy had not moved the paperweight since it arrived. The notice said: Audit Required. Documentation Must Be Provided. Tommy had not provided documentation because the documentation did not exist. The operation was undocumented by design. The IRS was methodical. The IRS was patient. The IRS had been patient for twenty years of Prohibition, and now that Prohibition was ending, the patience was converting itself into something that looked a lot like enforcement.

Salvatore Gucci, who ran the hardware store two blocks east, sometimes slipped extra copper tubing into Tommy's orders. He was sixty-eight, a retired union man, and the kind of guy who believed that keeping a neighbor's operation running was simply the decent thing to do in a city that had stopped believing in decency. He would load the tubing into Tommy's trunk and drive away before Tommy could offer payment, because some debts cannot be settled in cash and Salvatore understood this.

Tommy used the tubing sometimes. Sometimes he did not. He would watch it in the corner of the back room and think about how copper prices had risen and then he would let it sit and feel guilty about it for a fortnight. He attended Salvatore's funeral in the rain. He stood at the back of the church in a suit that fit poorly because he had lost fifteen pounds and had not registered the change because his mind was occupied by a condenser coil that needed repositioning by two millimeters.

After the service, he walked to his Packard and saw the postal worker placing a box on Salvatore's front porch. It was a still. Tommy's still. The one he had built for him in 1930, a year after Salvatore had started slipping him tubing. A compact design: a five-gallon pot with a three-foot column and a worm condenser, built from parts Tommy already owned and parts Salvatore already supplied. Salvatore had been using it. Every weekend. For three years. To make the limoncello his wife loved.

Tommy stood on the sidewalk and watched the still sit on Salvatore's garage shelf and thought about how he had designed it to produce two gallons per run and it had produced three years' worth of his friend's Saturday rituals, and he had never known.

Tommy sat at his steel table on a Tuesday in November. The back room was cold because the radiator had been stolen—again—and he had not replaced it. He wore three layers of clothing and a heavy coat and gloves with the fingertips cut so he could adjust the valves. He checked the hydrometer. 94 percent. He tightened a fitting. He checked again. 94 percent. He adjusted. 94.3 percent. Almost.

He set the hydrometer down. He picked up a pencil and wrote on a grease-spotted notebook: 0.3. Then he wrote: tomorrow. He sat in the back room for a while longer, looking at the operation. It was almost ready. It would always be almost ready. That was not failure. That was just how things were in a business built on almosts—almost legal, almost clean, almost profitable enough, almost worth the risk.

He stood. He went to the kitchen above the club. He put the percolator on. He waited for the coffee to brew. He poured the hot water over ground beans that had seen better decades. He carried the mug back to the back room and sat down and looked at the operation and said, out loud, for the first time in eighteen months: "Almost."

The radio on the shelf was playing a recording by a woman whose name Tommy could never recall. She was singing about a man who went away and came back to find everything different. Tommy listened to the recording, drank his coffee, and watched the operation sit on the steel table and was perfectly, completely still.

Almost.

The catalytic cycle that defined Tommy Callahan's existence operated through a series of low-activation-energy steps that accumulated into high-yield outcomes when properly balanced. The catalytic agent was not a person but a circumstance—the circumstance of being a man who understood that in a business built on prohibition, the most valuable commodity was not the product but the network of people who kept the product moving through channels that officially did not exist. Tommy had built this network one handshake at a time, one favor at a time, one almost at a time. Each connection was fragile. Each connection was necessary. Each connection was almost eternal. Salvatore had been one such connection. Salvatore had been almost enough. The operation on the steel table was almost ready to produce. The production would be almost sufficient. The profit would be almost adequate. The life would be almost livable. These were the operating parameters of a man who had spent fifteen years turning almost into something that moved and almost into something that paid and almost into something that kept him warm on cold Chicago nights when the wind came off the lake and carried the smell of the river and the river carried the smell of everything that had ever been dumped into it and nobody had officially acknowledged dumping anything into it because acknowledgment required承认 that the river was a commodity like any other and some commodities were better left unacknowledged.
