All my life, whenever problems of great import required discussion-health, family, money, marriage-the library was the place it was done. Yet my positive feelings about the room far outweigh my anxieties. The ash-paneled library is so much a part of my father's identity that he carries its scent wherever he goes-an aroma of fine wood, cigar smoke, aging leather, and whiskey. Born to working-class parents, he spent the first real money he made to build this room and fill it with books: Aristotle to Zoroaster and everything in between, with a special emphasis on the military campaigns of the Civil War. I feel more at home here than anywhere in the world. In this room I educated myself, discovered my gift for language, learned that the larger world lay not across oceans but within the human mind and heart. Years spent in this room made law school relatively simple and becoming a writer possible, even necessary.

Dad enters through a different door, carrying a bourbon-and-water brown enough to worry me. We each take one of the leather recliners, which are arranged in the classic bourgeois style: side by side facing the television. He clips the end of a Partagas, licks the end so that it won't peel, and lights it with a wooden match. A cloud of blue smoke wafts toward the beamed ceiling.

"Dad, I-"

"Let me start," he says, staring across the room at his biographies, most of them first editions. "Son, there comes a time in every man's life when he realizes that the people who raised him from infancy now require the favor to be returned, whether they know it or not." He stops to puff on the Partagas. "This is something you do not yet have to worry about."

"Dad-"

"I am kindly telling you to mind your own business. You and Annie are welcome here for the next fifty years if you want to stay, but you're not invited to pry into my private affairs."

I lean back in the recliner and consider whether I can honor my father's request. Given what my mother told me, I don't think so. "What's Ray Presley holding over you, Dad?"

"Your mother talks too much."

"You know that's not true. She thinks you're in trouble. And I can help you. Tell me what Presley has on you."

He picks up his drink and takes a long pull, closing his eyes against the anesthetic fire of the bourbon. "I won't have this," he says quietly.

I don't want to ask the next question-I'd hoped never to raise this subject again-but I must. "Is it something like what you did for Sarah? Helping somebody at the end?"

My father sighs like a man who has lived a thousand years. "That's a rare situation. And when things reach that point, the family's so desperate to have the horror and pain removed from the patient's last hours that they look at you like an instrument of God."

He drinks and stares at his books, lost in contemplation of something I cannot guess at. He has aged a lot in the eighteen years since I left home. His beard is no longer salt-and-pepper but silver white. His skin is pale and dotted by dermatitis, his joints eroded and swollen by psoriatic arthritis. He is sixteen years past his triple bypass (and counting) and he recently survived the implantation of two stents to keep his cardiac vessels open. All this-physical maladies more severe than those of most of his patients-he bears with the resignation of Job. The wound that aged him most, the one that has never quite healed, was a wound to the soul. And it came at the hands of another man.

When I was a freshman at Ole Miss, my father was sued for malpractice. The plaintiff had no case; his father had died unexpectedly while under the care of my father and five specialists. It was one of those inexplicable deaths that proved for the billionth time that medicine is an inexact science. Dad was as stunned as the rest of the medical community when "Judge" Leo Marston, the most prominent lawyer in town and a former state attorney general, took the man's case and pressed it to the limit. But no one was more shocked than I. Leo Marston was the father of a girl I had loved in high school, and whom I still think about more than is good for me. Why he should viciously attack my father was beyond my understanding, but attack he did. In a marathon of legal maneuvering that dragged on for fourteen months, Marston hounded my father through the legal system with a vengeance that appalled the town. In the end Dad was unanimously exonerated by a jury, but by then the damage had been done.

For a physician of the old school, medical practice is not a profession or even an art, but the abiding passion of existence. A brilliant boy is born to poor parents during the Depression. From childhood he works to put food on the table. He witnesses privation and sickness not at a remove, but face to face. He earns a scholarship to college but must work additional jobs to cover his expenses. He contracts with the army to pay for his medical education in exchange for years of military service. After completing medical school with an exemplary record, he does not ask himself the question every medical student today asks himself: what do I wish to specialize in? He is ready to go to work. To begin treating patients. To begin living.

For twenty years he practices medicine as though his patients are members of his family. He makes small mistakes; he is human. But in twenty years of practice not one complaint is made to the state medical board, or any legal claim made against him. He is loved by his community, and that love is his life's bread. To be accused of criminal negligence in the death of a patient stuns him, like a war hero being charged with cowardice. Rumor runs through the community like a plague, and truth is the first casualty. His confidence in the Tightness of his actions is absolute, but after months of endlessly repeated allegations, doubt begins to assail him. A lifetime of good works seems to weigh as nothing compared to one unsubstantiated charge. Smiles on the street appear forced to him, the greetings of neighbors cool. Stress works steadily and ruthlessly upon him, finally culminating in a myocardial infarction, which he barely survives.

Six weeks later the trial begins, and it's like stepping into the eye of a hurricane. Control rests in the hands of lawyers, men with murky motives and despicable tactics. Expert witnesses second-guess every medical decision. He sits alone in the witness box, condemned before family, friends, and community, cross-examined as though he were a child murderer. When the jury finds in his favor, he feels no joy. He feels like a man who has just lost both legs being told he is lucky to be alive.

Could the present-day blackmail somehow be tied to that calamitous case? I have never understood the reason for Leo Marston's attack, and I've always felt that my father-against his nature-must have been keeping the truth from me. My mother believes Ray Presley is behind the blackmail, and I recall that Judge Marston often hired Presley to do "security work" when I was in high school. This translated into acting as unofficial baby-sitter for Marston's teenage daughter, Olivia, who was also my lover. I remember nights when Presley's truck would swing by whatever hangout the kids happened to be frequenting, its hatchet-faced driver glaring from the window, making sure Livy didn't get into any serious trouble. One night Presley actually pulled up behind my car in the woods and rapped on the fogged windows, terrifying Livy and me. I still remember his face peering into the clear circle I rubbed on the window to look out, his eyes bright and ferretlike, searching the backseat for a sight of Livy unclothed. The hunger in those eyes…

"Does this have anything to do with Leo Marston?" I ask softly.

Dad flinches from his reverie. Even now the judge's name has the power to harm. "Marston?" he echoes, still staring at his books. "What makes you say that?"
