At last his strong baritone filters around the door. The volume tells me he is bidding farewell to a geriatric patient. Old people comprise the bulk of his practice now, as his "patient base" has aged with him. Anna leans in and gives me a smile, then closes the door behind Dad. He squeezes my shoulder as he walks past and sits in the big chair behind his desk.

This is how I picture him in memory: white lab coat, stethoscope hanging loosely around his neck, ensconced behind mountains of incomplete medical records, drug samples, and junk mail. He reaches into a small refrigerator behind his desk and takes out a Dr Pepper, which he offers to me. When I decline, he pops the top and takes a long pull from it, his eyes watering from the sudden shot of carbonation.

"I'm in a bad spot, Penn," he says in a frank voice. "I apologize for being an ass the other night. It's not easy for a father to admit weakness to his son."

I nod awkwardly, imagining a future when I am certain to fall short of Annie's idealized image of me. "Dad, there's nothing you can tell me that will change my opinion of you. Just tell me what's going on so we can deal with it."

He clearly doubts my statement, but he's made up his mind to talk. "Twenty-five years ago," he says, "your Aunt Ellen got into some trouble."

My mind is spinning. When he said "twenty-five years ago," I thought he was going to start talking about Del Payton. But Payton was killed thirty years ago. The shift to my mother's younger sister, Ellen, throws me completely.

"She was divorced and living in Mobile, Alabama. Ellen was about your age now, I guess. Dating a guy there. He was a year or two younger than she was. Name was Hillman. Don Hillman. Your mother and I didn't know it at the time-at least I didn't-but Hillman was abusing Ellen. Beating her, controlling every word and action. Your mother finally convinced her that the relationship was going to end badly no matter what she did, and Ellen tried to break it off. Hillman didn't take it well. I advised Ellen to go to the police. Then I found out Hillman was the brother of a cop over in Mobile. A detective. This was 1973. Nobody'd heard of stalking laws."

"I hope you brought her here."

"Of course. She stayed with us for a summer. You remember, don't you?"

I do. For most of one summer our hall bathroom became an exotic world of hanging stockings, lacy underwear, cut-glass perfume bottles, and blue Noxema jars.

"Hillman called the house a few times after the breakup. Late, drunk out of his mind and railing, or else hanging up. One night when he didn't hang up, I told him if he came to Natchez making trouble, he'd be a long time getting back to Mobile. The calls stopped. After a while Ellen wanted her own place, so I rented her an apartment at the Windsor Arms and got her a job at the Jeff Davis."

He takes another slug of Dr Pepper. "As soon as she got her own place, strange things started happening. Slashed tires, eggs on her door, more juvenile crap. One morning she found her cat at her door with its throat cut. I called the Natchez police, but they couldn't find Hillman anywhere in town." He closes his eyes and sighs. "Then he raped her."

A shudder of horror accompanies my amazement. Families are mazes of secrets, and none of us ever knows them all.

"Hillman was waiting inside her apartment when she got home from a date. He beat the hell out of her, raped her, sodomized her. Then he disappeared. Ellen was too shaken up to swear out charges. I had to sedate her. I got the Natchez D.A. to call the Mobile D.A. and make a lot of noise, but Ellen would have been a shaky witness at best, even if I could have gotten her to press charges. And Hillman's brother was a cop, remember? The Mobile D.A. didn't sound excited about making trouble for him."

I nod in sympathy. The old-timers in Houston told me a thousand times how tough it was to get rape convictions before feminists changed public perception of the crime. And the cop angle was a serious complication. Nothing is more incestuous than Southern law enforcement. Everything is personal relationships.

"Needless to say, things were pretty bad at home," Dad goes on. "We tried to keep it from you and your sister, but your mother and Ellen were at the end of their rope. Peggy was driving her to Jackson every three days to see a psychiatrist."

I remember this too. Mom taking Aunt Ellen to the doctor all the time. "We thought it was her ovaries or something."

"That's what we told you. Anyway, two weeks after the rape, Hillman started calling again." Dad is clenching and unclenching his right fist on the desk. "I never felt so goddamn impotent in my life."

I don't know what's coming, but the hair on my forearms is standing up.

"About this time, Ray Presley happened to come see me about his blood pressure. You know how I get to talking to patients, and Presley always had a good story. He saw that I wasn't myself. He asked what was bothering me, and I told him. He'd been a cop, after all. I thought he might have a suggestion."

He'd also done a hitch in Parchman prison, I think, but now does not seem the best time to bring that up.

"Ray heard me out, and he didn't say much. Grunted a couple of times in the right places. You never know what he's thinking. So we're both just sitting there, saying nothing. After a while he says, 'So what's this shitbird's name, Doc?' I didn't say anything for a minute. Then I told him. We shot the bull for a few more minutes, and Ray left. Three weeks later, the Natchez D.A. called and told me Hillman was dead. Somebody'd shot him in the head and taken his wallet outside a topless bar in Mobile."

"Jesus Christ."

"At first I was relieved. But somewhere in the back of my mind I was worried about Ray. He'd always appreciated me taking care of his mother, and some part of me wondered if he hadn't taken it into his head to get rid of my problem for me."

"Oh, man."

"A month later he came back in to get his pressure checked. I told the girls I was too busy to talk, but he slipped into my office and waited for me. When I went in, I asked him point blank if he knew anything about Hillman's death."

"And?"

"He told me right out he'd killed the guy."

"Shit."

Dad shakes his head. "Just like saying, 'I fixed that flat for you, Doc.' He gave me this funny smile and told me not to give it another thought. Said I didn't owe him anything. Just get back to doctoring and living. Those were his exact words."

"Tell me you reported this to the police."

"I didn't."

Having watched my father make moral choices that cost him money and friendships for years, I am stunned by this answer. "That's accessory after the fact, Dad. Five years in the pen."

"I realize that. But the situation was more complicated than you know."

"You hadn't committed any crime until you kept Presley's confession from the police."

"Listen, damn it! Ray must have seen how he upset me. Because twenty minutes after he walked out, he came back and handed me a zipper pouch. Inside it was a pistol I'd lent him about six months before, a forty-five."

My heart slaps against my chest wall. "He killed Hillman with that pistol?"

"No. But he was always borrowing things from me back then. Guns, books, my Nikon for a stakeout, that kind of thing. You know I can't say no to anybody. Anyhow, I'd lent him another pistol about a year before, a little featherweight thirty-eight. So, when he handed me the forty-five, I asked about the thirty-eight." Dad takes a deep breath and exhales slowly. "He told me it had been stolen."

I close my eyes as though to shield myself from what is coming.

"He told me not to worry about it, that he'd get me another thirty-eight. But he was really telling me that reporting the murder wasn't an option. He'd killed Hillman with my thirty-eight, and he still had the gun. If I tried to report him, he could tell the police that I'd asked him to commit the crime and had given him the gun to do it."
