“Yes. I needed to make sure he’s capable of doing it. Ozzie’s a bad man, Jake—what people back in ’58 call a louse—but beating on your wife and keeping her a virtual prisoner because she doesn’t speak the language don’t justify murder. And something else. Even if I hadn’t come down with the big C, I knew I might not get another chance to make it right if I killed Oswald and someone else shot the president anyway. By the time a man’s in his sixties, he’s pretty much off the warranty, if you see what I mean.”

“Would it have to be killing? Couldn’t you just . . . I don’t know . . . frame him for something?”

“Maybe, but by then I was sick. I don’t know if I could have done it even if I was well. On the whole it seemed simpler to just end him, once I was sure. Like swatting a wasp before it can sting you.”

I was quiet, thinking. The clock on the wall said ten-thirty. Al had opened the conversation by saying he’d be good to go until midnight, but I only had to look at him to know that had been wildly optimistic.

I took his glass and mine out to the kitchen, rinsed them, and put them in the dish drainer. It felt like there was a tornado funnel behind my forehead. Instead of cows and fenceposts and scraps of paper, what it was sucking up and spinning around were names: Lee Oswald, Bobby Oswald, Marina Oswald, Edwin Walker, Fred Hampton, Patty Hearst. There were bright acronyms in that whirl, too, circling like chrome hood ornaments ripped off luxury cars: JFK, RFK, MLK, SLA. The cyclone even had a sound, two Russian words spoken over and over again in a flat Southern drawl: pokhoda, cyka.

Walk, bitch.

“How long have I got to decide?” I asked.

“Not long. The diner goes at the end of the month. I talked to a lawyer about buying some more time—tying them up in a suit, or something—but he wasn’t hopeful. Ever seen a sign in a furniture store saying LOST OUR LEASE, EVERYTHING MUST GO?”

“Sure.”

“Nine cases out of ten that’s just sales-pitch bullshit, but this is the tenth case. And I’m not talking about some discount dollar store bumping to get in, I’m talking about Bean’s, and when it comes to Maine retail, L.L. Bean is the biggest ape in the jungle. Come July first, the diner’s gone like Enron. But that isn’t the big thing. By July first, I might be gone. I could catch a cold and be dead of pneumonia in three days. I could have a heart attack or a stroke. Or I could kill myself with these damn OxyContin pills by accident. The visiting nurse who comes in asks me every day if I’m being careful not to exceed the dosage, and I am careful, but I can see she’s still worried she’ll walk in some morning and find me dead, probably because I got stoned and lost count. Plus the pills inhibit respiration, and my lungs are shot. On top of all that, I’ve lost a lot of weight.”

“Really? I hadn’t noticed.”

“Nobody loves a smartass, buddy—when you get to be my age, you’ll know. In any case, I want you to take this as well as the notebook.” He held out a key. “It’s to the diner. If you should call me tomorrow and hear from the nurse that I passed away in the night, you’ll have to move fast.

Always assuming you decide to move at all, that is.”

“Al, you’re not planning—”

“Just trying to be careful. Because this matters, Jake. As far as I’m concerned, it matters more than anything else. If you ever wanted to change the world, this is your chance. Save Kennedy, save his brother. Save Martin Luther King. Stop the race riots. Stop Vietnam, maybe.” He leaned forward. “Get rid of one wretched waif, buddy, and you could save millions of lives.”

“It’s a hell of a sales pitch,” I said, “but I don’t need the key. When the sun comes up tomorrow, you’ll still be on the big blue bus.”

“Ninety-five percent probability. But that’s not good enough. Take the goddam key.” I took the goddam key and put it in my pocket. “I’ll let you get some rest.”

“One more thing before you go. I need to tell you about Carolyn Poulin and Andy Cullum.

Sit down again, Jake. This’ll take a few minutes.”

I stayed on my feet. “Uh-uh. You’re used up. You need to sleep.”

“I’ll sleep when I’m dead. Sit down.”

After discovering what he called the rabbit-hole, Al said, he was at first content to use it to buy supplies, make a few bets with a bookie he found in Lewiston, and build up his stash of fifties cash. He also took the occasional midweek holiday on Sebago Lake, which was teeming with fish that were tasty and perfectly safe to eat. People worried about fallout from A-bomb tests, he said, but fears of getting mercury poisoning from tainted fish were still in the future. He called these jaunts (usually Tuesdays and Wednesdays, but he would sometimes stay all the way to Friday) his minivacations. The weather was always good (because it was always the same weather) and the fishing was always terrific (he probably caught at least some of the same fish over and over).

“I know exactly how you feel about all this, Jake, because I was pretty much in shock those first few years. You want to know what’s a mind-blower? Going down those stairs at the height of a January nor’easter and coming out in that bright September sunshine. Shirtsleeve weather, am I right?”

I nodded and told him to go on. The little bit of color that had been in his cheeks when I came in was all gone, and he was coughing steadily again.

“But if you give a man some time, he can get used to anything, and when the shock finally started to wear off, I started to think I’d found that old rabbit-hole for a reason. That’s when I started to think about Kennedy. But your question reared its ugly head: can you change the past? I wasn’t concerned about the consequences—at least not to start with—but only about whether or not it could be done at all. On one of my Sebago trips, I took out my knife and carved AL T. FROM 2007 on a tree near the cabin where I stayed. When I got back here, I jumped in my car and drove on over to Sebago Lake. The cabins where I stayed are gone; there’s a tourist hotel there now. But the tree is still there. So was what I carved into it. Old and smooth, but still there: AL T. FROM 2007. So I knew it could be done. Then I started thinking about the butterfly effect.

“There’s a newspaper in The Falls back then, the Lisbon Weekly Enterprise, and the library scanned all their microfilm into the computer in ’05. Speeds things up a lot. I was looking for an accident in the fall or early winter of 1958. A certain kind of accident. I would have gone all the way into early 1959 if necessary, but I found what I was looking for on November fifteenth of ’58. A twelve-year-old girl named Carolyn Poulin was hunting with her father across the river, in the part of Durham that’s called Bowie Hill. Around two o’clock that afternoon—it was a Saturday—a hunter from Durham named Andrew Cullum shot at a deer in that same section of the woods. He missed the deer, hit the girl. Even though she was a quarter of a mile away, he hit the girl. I think about that, you know. When Oswald shot at General Walker, the range was less than a hundred yards. But the bullet clipped the wood sash in the middle of a window and he missed. The bullet that paralyzed the Poulin girl traveled over four hundred yards— much farther than the shot that killed Kennedy—and missed every tree trunk and branch along the way. If it had even clipped a twig, it almost surely would have missed her. So sure, I think about it.” That was the first time the phrase life turns on a dime crossed my mind. It wasn’t the last. Al grabbed another maxi pad, coughed, spat, tossed it in the wastebasket. Then he drew in the closest thing to a deep breath he could manage, and labored on. I didn’t try to stop him. I was fascinated all over again.
