There is a student lounge on the first floor of the Yale Law School, and on the walls outside its door are posters and notices advertising internships and even careers in public-interest law. The students are encouraged to consider spending a few years helping battered women, neglected children, death row inmates, immigrants, runaway teens, indigent defendants, the homeless, asylum seekers, Haitian boat refugees, Americans sitting in foreign jails and foreigners sitting in American jails, First Amendment projects, innocence projects, conservation groups, environmental activists, and on and on.

A belief in public service runs deep at Yale Law. Admission is often determined by the applicant's record of volunteerism and his or her written thoughts about using a law degree to benefit the world. First-year students are inundated with the virtues of public-interest law and are expected to get involved as soon as possible.

And most do. Around 80 percent of all freshmen claim that they are attracted to the law by a desire to help others. At some point, though, usually about halfway through the second year, things begin to change. The big firms arrive on campus to interview and begin their selection process. They offer summer internships, with nice salaries and the prospect of ten weeks of fun and games in New York, Washington, or San Francisco. Most important, they hold the keys to the lucrative careers. A divide occurs at Yale Law, as it does at all prestigious schools. Many of those so enamored with righteous dreams of aiding the downtrodden suddenly switch gears and begin dreaming of making it to the major leagues of American law, while many are turned off by this seduction and cling to their idyllic notions of public service. The divide is clear, but civilized.

When an editor of the Yale Law Journal takes a low-paying job with legal services, he is a hero to those on his side and to most of the faculty. And when he suddenly caves in to Wall Street, he is viewed less favorably by the same people.

Kyle's life became miserable. His friends on the public-interest side were in disbelief. Those on the corporate side were too busy to care. His relationship with Olivia was reduced to sex once a week and only because they needed it. She said he had changed. He was moodier, gloomier, preoccupied with something, and whatever it was he couldn't tell her.

If you only knew, he thought.

She had accepted a summer internship with an anti-death-penalty group in Texas; thus she was full of zeal and big plans to change things down there. They saw less and less of each other but somehow managed to bicker more.

One of Kyle's favorite professors was an old radical who'd spent most of the 1960s marching for or against something, and he was still the first one to organize a petition against whatever he perceived to be the latest injustice on campus. When he heard the news that Kyle had flipped, he called and demanded lunch. Over enchiladas at a taco bar just off campus, they argued for an hour. Kyle pretended to resent the intrusion, but in his heart he knew he was wrong. The professor railed and hammered and got nowhere. He left Kyle with a disheartening "I'm very disappointed in you."

"Thanks," Kyle retorted, then cursed himself as he walked to campus. Then he cursed Bennie Wright and Elaine Keenan and Scully & Pershing and everything else in his life at that moment. He was mumbling and cursing a lot these days.

After a few rounds of ugly encounters with his friends, Kyle finally found the courage to go home.

THE MCAVOYS DRIFTED into eastern Pennsylvania in the late eighteenth century, along with thousands of other Scottish settlers. They farmed for a few generations, then moved on, down to Virginia, the Carolinas, and even farther south. Some stayed behind, including Kyle's grandfather, a Presbyterian minister who died before Kyle was born. Reverend McAvoy led several churches on the outskirts of Philadelphia before being transferred to York in 1960. His only son, John, finished high school there and returned home after college, Vietnam, and law school.

In 1975, John McAvoy quit his job as a lowly paid pencil pusher in a small real estate law firm in York. He marched across Market Street, rented a two-room "suite" in a converted row house, hung out his shingle, and declared himself ready to sue. Real estate law was too boring. John wanted conflict, courtrooms, drama, verdicts. Life in York was uneventful enough. He, an ex-Marine, was looking for a fight.

He worked very hard and treated everyone fairly. Clients were free to call him at home, and he would meet them on Sunday afternoons if necessary. He made house calls, hospital calls, jail calls. He called himself a street lawyer, an advocate for clients who worked in factories, who got injured or discriminated against, or who ran afoul of the law. His clients were not banks or insurance companies or real estate agencies or corporations. His clients were not billed by the hour.

Often, they were not billed at all. Fees were sometimes delivered in the form of firewood, eggs and poultry, steaks, and free labor around the house. The office grew, sprawled upstairs and down, and John eventually bought the row house. Younger lawyers came and went, none staying more than three years. Mr. McAvoy was demanding of his associates. He was kinder to his secretaries. One, a young divorcee named Patty, married the boss after a two-month courtship and was soon pregnant.

The Law Offices of John L. McAvoy had no specialty, other than representing low-paying clients. Anyone could walk in, with an appointment or without, and see John as soon as he was available. He handled wills and estates, divorces, injuries, petty criminal cases, and a hundred other matters that found their way to his office on Market Street. The traffic was constant, the doors opened early and closed late, and the reception area was seldom empty. Through sheer volume, and an innate Presbyterian frugality, the office covered its expenses and provided the McAvoy family with an income that was in the upper-middle class for York. Had he been greedier, or more selective, or even a bit firmer with his billing, John could have doubled his income and joined the country club. But he hated golf and didn't like the wealthier folks in town. More important, he viewed the practice of law as a calling, a mission to help the less fortunate.

Patty had twin girls in 1980. In 1983, Kyle was born, and before he started kindergarten, he was hanging around his father's office. After his parents divorced, he preferred the stability of the law office to the strains of joint custody, and each day after school he parked himself in a small room upstairs and finished his homework. At the age of ten he was running the copier, making coffee, and tidying up the small library. He was paid $1 an hour in cash. By the age of fifteen he had mastered legal research and could hammer out memos on basic subjects. During high school, when he wasn't playing basketball, he was at the office or in court with his father.

Kyle loved the law office. He chatted up the clients as they waited to see Mr. McAvoy. He flirted with the secretaries and pestered the associates. He cracked jokes when things were tense, especially when Mr. McAvoy was angry with a subordinate, and he pulled pranks on visiting lawyers. Every lawyer and every judge in York knew Kyle, and it was not unusual for him to slip into an empty courtroom, present a motion to a judge, argue its merits if necessary, then leave with a signed order. The court clerks treated him as if he were one of the lawyers.

Before college, he was always around the office at five on Tuesday afternoons when Mr. Randolph Weeks stopped by with a delivery of food  -  fruits and vegetables from his garden in the spring and summer and pork, poultry, or wild game in the fall and winter. Every Tuesday at 5:00 p.m. for at least the past ten years, Mr. Weeks came to pay a portion of his fee. No one knew exactly how much was owed or how much had been paid, but Mr. Weeks certainly felt as though he was still in debt to Mr. McAvoy. He had explained to Kyle many years earlier that his father, a great lawyer, had pulled a miracle and kept Mr. Weeks's oldest son out of prison.

And Kyle, though only a teenager, had been the unofficial lawyer for Miss Brily, a crazy old woman who'd been run out of every law office in York. She trudged the streets of the town with a wooden file cabinet on wheels, boxes of papers which she claimed proved clearly that her father, who had died at the age of ninety-six (and she still suspected foul play), was the rightful heir to a huge tract of rich coal deposits in eastern Pennsylvania. Kyle had read most of her "documents" and had quickly concluded that she was even nuttier than most lawyers suspected. But he engaged her and listened to her conspiracies. By then he was earning $4 an hour and worth every penny of it. His father often parked him in the reception area to screen those new clients who at first glance showed the potential to waste a lot of his time.

Except for the usual adolescent dreams of playing professional sports, Kyle always knew he would be a lawyer. He wasn't sure what kind of lawyer, or where he would practice, but by the time he left York for Duquesne, he doubted if he would return. John McAvoy doubted it, too, though, like any father, he often thought of the pride he would have if the firm name became McAvoy & McAvoy. He demanded hard work and excellent grades, but even he was a little surprised at Kyle's academic success in college and at Yale Law School. When Kyle began his interviews with the big corporate law firms, John had plenty to say on the matter.

KYLE HAD CALLED and told his father he would arrive in York late Friday afternoon. They had agreed on dinner. As usual, the office was busy at 5:30, when he arrived. Most law firms closed early on Friday, and most lawyers were either in bars or at the country club. John McAvoy worked late because many of his clients got paid at the end of the week, and a few stopped by to write small checks or see about their cases. Kyle had not been home in six weeks, since Christmas, and the office looked even shabbier. The carpet needed replacing. The bookshelves sagged even more. His father couldn't stop smoking; therefore smoking was permitted, and a thick haze floated near the ceiling late in the day.

Sybil, the ranking secretary, abruptly hung up the phone when Kyle walked through the door. She jumped to her feet, squealed, grabbed him, and thrust her gigantic breasts at him. They pecked on the cheeks and enjoyed the physical greeting. His father had handled at least two divorces for Sybil, and the current husband would soon be on the street. Kyle had heard the details during the Christmas break. The firm currently had three secretaries and two associates, and he went from room to room, downstairs first, then upstairs, where the young lawyers were kept, speaking to the employees as they packed their briefcases and purses and tidied up their desks. The boss might enjoy staying late on Fridays, but the rest of the firm was tired.

Kyle drank a diet soda in the coffee room and listened to the voices and sounds of the office as it wound down. The contrasts were startling. Here, in York, the firm was filled with co-workers who were friends who could be trusted. The pace was busy at times, but never frantic. The boss was a good guy, someone you would want as your lawyer. The clients had faces and names. The lawyers across the street were old pals. It was a different world from the hard streets of New York City.

Not for the first time he asked himself why he didn't tell his father everything. Just spill it all. Start with Elaine, her allegations, the cops and their questions. Five years earlier he had come within minutes of hustling home and asking his father for help. But then it passed, and then it went away, and John McAvoy was never burdened with the ugly episode. None of the four  -  Kyle, Joey Bernardo, Alan Strock, and Baxter Tate  -  had told their parents. The investigation ran out of steam before they were forced to.

If he told his father now, the first question would be, "Why didn't you tell me then?" And Kyle wasn't prepared to face it. Many tougher questions would follow, a regular cross-examination by a courtroom brawler who'd interrogated his son since he was an infant. It was much easier for Kyle to keep his secrets and hope for the best.

What he was about to tell his father was difficult enough.

After the last client left and Sybil said goodbye and locked the front door, father and son relaxed in the big office and talked about college basketball and hockey. Then family, the twin sisters first, as always, then Patty.

"Does your mother know you're in town?" John asked.

"No. I'll call her tomorrow. She's okay?"

"Nothing's changed. She's fine." Patty lived and worked in the loft of an old warehouse in York. It was a large space with lots of windows that provided the light she needed to pursue her painting. John paid the rent, utilities, and everything else she needed through a monthly stipend of $3,000. It wasn't alimony, and it certainly wasn't child support, but simply a gift he felt compelled to pass along for her upkeep because she could not support herself. If she had sold a painting or a sculpture in the past nineteen years, no one in the family knew about it.

"I call her every Tuesday night," Kyle said.

"I know you do."

Patty had no use for computers or cell phones. She was severely bipolar, and the mood swings were, at times, astonishing. John still loved her and had never remarried, though he'd enjoyed a few girlfriends. Patty had been through at least two ruinous affairs, both with fellow artists, much younger men, and John had been there to pick up the pieces. Their relationship was complicated, to say the least.

"So how's school?" John asked.

"Downhill. I graduate in three months."

"That's hard to believe."

Kyle swallowed hard and decided to get it over with. "I've changed my mind about employment. I'm going to Wall Street. Scully & Pershing."

John slowly lit another cigarette. He was sixty-two, thick but not fat, with a head full of wavy gray hair that began no more than three inches above his eyebrows. Kyle, at twenty-five, had lost more hair than his father.

John took a long drag from his Winston and studied his son from behind wire-rimmed reading glasses perched on his nose. "Any particular reason?"

The list of reasons had been memorized, but Kyle knew they would sound flat regardless of how smoothly they were delivered. "The legal services gig is a waste of time. I'll end up on Wall Street eventually, so why not get the career started?"

"I don't believe this."

"I know, I know. It's an about-face."

"It's a sellout. There's nothing that requires you to pursue a career in a corporate firm."

"It's the big leagues, Dad."

"In terms of what? Money?"

"That's a start."

"No way. There are trial lawyers who make ten times more each year than the biggest partners in New York."

"Yes, and for every big trial lawyer there are five thousand starving sole practitioners. On the average, the money is much better in a big firm."

"You'll hate every minute of a big firm."

"Maybe not."

"Of course you will. You grew up here, around people and real clients. You won't see a client for ten years in New York."

"It's a nice firm, Dad. One of the best."

John yanked a pen from his pocket. "Let me write this down, so a year from now I can read it back to you."

"Go ahead. I said, 'It's a nice firm. One of the best.' "

John took notes and said, "You're gonna hate this firm and its lawyers and cases, and you'll probably even hate the secretaries and the other rookie associates. You're gonna hate the grind, the routine, the sheer drudgery of all the mindless crap they dump on you. Response?"

"I disagree."

"Great," John said, still writing. Then he pulled on the cigarette and blew out an impressive cloud of smoke. He put down the pen. "I thought you wanted to try something different and help people in the process. Did I not hear these words from you just a few weeks ago?"

"I've changed my mind."

"Well, change it back. It's not too late."

"No."

"But why? There must be a reason."

"I just don't want to spend three years in rural Virginia trying to learn enough Spanish so I can listen to the problems of people who are here illegally in the first place."

"I'm sorry, but that sounds like a great way to spend the next three years. I don't buy it. Give me another reason." With that, John shoved his leather swivel chair back and jumped to his feet. Kyle had seen this a million times. His father preferred to pace and toss his hands about when he was agitated and firing questions. It was an old habit from the courtroom, and it was not unexpected.

"I'd like to make some money."

"For what? To buy things, some new toys? You won't have the time to play with them."

"I plan to save - "

"Of course you will. Living in Manhattan is so cheap you'll save a fortune." He was walking in front of his Ego Wall, framed certificates and photos almost to the ceiling. "I don't buy it, and I don't like it." His cheeks were turning colors. The Scottish temper was warming up.

Speak softly, Kyle reminded himself. A sharp word or two would make things much worse. He would survive this little clash, as he had survived the others, and one day soon all the harsh words would be over and Kyle would be off to New York.

"It's all about the money, isn't it, Kyle?" John said. "You were raised better."

"I'm not here to be insulted, Dad. I've made my decision. I ask you to respect it. A lot of fathers would be thrilled with such a job."

John McAvoy stopped pacing and stopped smoking, and he looked across his office at the handsome face of his only son, a twenty-five-year-old who was quite mature and unbelievably bright, and he decided to back off. The decision was made. He'd said enough.

Any more and he might say too much. "Okay," he said. "Okay. It's all you. You're smart enough to know what you want, but I'm your father and I'll have some opinions about your next big decision, and the next. That's what I'm here for. If you screw up again, I'll damned sure let you know it."

"I'm not screwing up, Dad."

"I will not bicker."

"Can we go to dinner? I'm starving."

"I need a drink."

THEY RODE TOGETHER to Victor's Italian Restaurant, John's Friday night ritual for as long as Kyle could remember. John had his usual end-of-the-week martini. Kyle had his standard drink  -  club soda with a twist of lime. They ordered pasta with meatballs, and after the second martini John began to mellow. Having his son at the largest and most prestigious law firm in the country did have a nice ring to it.

But he was still puzzled by the abrupt change in plans.

If you only knew, Kyle kept saying to himself. And he ached because he couldn't tell his father the truth.
