Littlejohn hesitates, a small stutter step, his eyes flas.h.i.+ng with fear and confusion, and my heart catches in my throat, because I'm right-I knew I was right, and yet I cannot believe it. I'm staring at him, imagining those soft hands winding a long black belt around Peter Zell's neck, slowly tightening. Imagining a pistol trembling in his hand, Naomi's big black eyes.

A moment more, Palace. A moment more.

"I believe you are mistaken, Doctor," he says quietly to Fenton.

"No mistake," she replies briskly, smiling tightly, rea.s.suringly at McConnell. She's enjoying this, Fenton. Littlejohn keeps pus.h.i.+ng, what choice does he have? "No, you are incorrect, that room is out of service. It is locked."

"Yes," I say, and Littlejohn jumps, in this instant he knows exactly what's going on, he looks around the room and I step out of the darkness with my sidearm raised. "And you have the key. Where is the key, please?"

He looks at me, dumbstruck.

"Where is the key, sir?"

"It's-" he closes his eyes, opens them again, the blood draining from his face, hope dying in his eyes. "It's in my office."

"We'll go there."

McConnell has drawn her weapon from her black pocketbook. Fenton stays put, her eyes glinting behind her round gla.s.ses, enjoying every second.

"Detective." Littlejohn steps forward, he's making an effort, his voice trembling, but he's trying. "Detective, I can't imagine-"

"Quiet," I say. "Quiet, please."

"Yes, but Detective Palace, I don't know what you're thinking, but if you ... if you think ..."

Feigned confusion distrorts his handsome features. It's there, the truth is there, even in the fact that my name comes so easily to mind: he's known exactly who I am since the day I caught this case, since I called his wife to arrange an interview, he's been on to me, tailing me, interposing himself between me and my ongoing investigation. Encouraging Sophia, for example, to evade my questions, selling her on the attenuated notion that it would upset her father. Selling me on how depressed his brother-in-law was. Watching outside the house, waiting, while I interviewed J. T. Toussaint. And then, a Hail Mary, unhooking the chains on my snow tires.

And he was at Toussaint's again, the house on Bow Bog Road, scrabbling around looking for the leftover merchandise, the phone numbers, client lists. Looking for the same things I was, except he knew what we were looking for and I didn't, and then I chased him off before he could think to search the doghouse.

But he had one more trick to play, one more way to shove me in the wrong direction. One more brutal trick to play, and it almost worked.

Officer McConnell steps forward, drawing handcuffs from the small pocketbook, and I say, "Wait."

"What?" she asks.

"I just-" my gun still leveled on Littlejohn. "I'd like to hear the story first."

"I am sorry, Detective," he says, "but I don't know what you're talking about."

I release the safety. I think that if he keeps lying, I might kill him. I might just do it.

But he does, he talks. Slowly, softly, his voice dead and toneless, staring not at me but into the barrel of my firearm, he tells the story. The story that I already know, that I already figured out.

After October, when Sophia discovered that her brother had stolen her prescription pad and was using it to score pain pills-after she confronted him and cut him off-after Peter slipped into the brief painful period of withdrawal, and Sophia thought the whole thing was at an end-after all of that, Erik Littlejohn went to J. T. Toussaint and made him a proposition.

At that time, with Maia in conjunction and the odds of impact hovering at an agonizing fifty percent, the hospital was working at half staff: pharmacists and pharmacists' a.s.sistants were quitting in droves, and new people were being hired, glad for a salary backed by government money. Security was, and remains, all over the map. Some days, armed guards with machine guns; other days, the doors to locked wards propped open with folded-over magazines. Pyxis, the state-of-the-art mechanized pill dispensary, stopped working in September, and the technician a.s.signed by the manufacturer to Concord Hospital could not be located.

The director of Spiritual Services, in this time of desperation and wildness, has remained at his post, a trusted and constant figure, a rock. And he was, as of November, stealing vast quant.i.ties of medicine from the hospital pharmacy, from the nurses' stations, from patients' bedsides. MS Contin, Oxycontin, oxytocin, Dilaudid, half-empty bags of liquid morphine.

Through all of this, my gun does not waver, pointed at his face: his golden eyes half closed, the mouth set, expressionless.

"I promised Toussaint that I would keep him supplied," he says. "I told him I would take the risk of procuring the pills, if he would take the risk of selling them. We split the risk, and we split the profit."

Money, I'm thinking, just stupid money. So small, so squalid, so dull. Two murders, two bodies in the ground, all those people suffering, doing with half doses of their pills, with the world about to end? I gape at the murderer, looking him up and down. Is this a man who does all that for gain? For a gold watch and a new leather jacket?

"But Peter found out," I say.

"Yes," Littlejohn whispers, "he did," and he lowers his head and shakes it slowly, sadly, back and forth, as if remembering some regrettable act of G.o.d. Someone had a stroke, someone fell down the stairs. "He-it was last Sat.u.r.day night-he showed up at J. T.'s house. It was late. I only went there very late."

I exhale, grit my teeth. No escaping the fact that if Peter was at J. T.'s very late on a Sat.u.r.day night-a meeting J. T. had not mentioned to me-then he was there for a fix. He had his nightly call with Naomi, his support system who was herself secretly using morphine; he told her he was doing fine, holding up, and then he went to J. T.'s to get high as a satellite; and then his brother-in-law of all people shows up, his brother-in-law who, unbeknownst to him, is delivering a fresh supply.

Everybody with secrets, squirreled away.

"He sees me, I'm holding a duffel bag for G.o.d's sake, and I just said, 'please, please, please don't tell your sister.' But I knew-I knew he-" He stops himself, brings a hand to his mouth.

"You knew you had to kill him."

He moves his head very slightly up and down.

He was right: Peter would have told Sophia. In fact, he had called her for that purpose the next day, Sunday, March 18, and again on Monday, but she didn't answer. He sat down to write her a letter, but couldn't find the words.

So, on Monday night, Erik Littlejohn went to see Distant Pale Glimmers at the Red River, where he knew he would find his brother-in-law, the quiet insurance man. And there he is with their mutual friend J. T. Toussaint, and after the movie Peter tells J. T. to take off, he wants to walk home-Littlejohn caught a break on that one-because now Peter is alone. And what do you know, here's Erik, and Erik says, let's have a beer, let's catch up-let's make amends before everything happens.

And they're drinking their beers, and from his pocket he takes a small vial, and when Peter has pa.s.sed out he drags him from the theater, n.o.body notices, n.o.body cares, he takes him to the McDonald's to hang him in the bathroom.

McConnell puts the suspect in the handcuffs and I guide him by the bicep to the elevator, Fenton trailing behind us, and we ascend in silence: coroner, murderer, cop, cop.

"Holy c.r.a.p," says Fenton, and McConnell says, "I know."

I don't say anything. Littlejohn doesn't say anything.

The elevator stops and the doors open onto the lobby and it's crowded and among the crowd is a preadolescent boy, waiting there on one of the sofas, and Littlejohn's whole body goes tense, and mine does, too.

He had told Fenton that he could come down to the morgue to help with a body at 9:30, but he had a visitor coming at 10.

Kyle looks up, stands up, stares, wide-eyed and baffled, his father in handcuffs, and Littlejohn can't take it, he hurls his body out of the elevator, and I'm holding fast to his arm, and the force of his body in motion pulls me forward, too, both of us together. We land on the floor and go into a roll.

McConnell and Fenton spill out of the elevator, the lobby is full of people, doctors and volunteers, dodging out of the way and hollering as Littlejohn and I go end over end. Littlejohn bangs his forehead up and slams it into mine just as I'm drawing for my sidearm, and the force of the impact sends an explosion of pain into my wounded eye, throws a sky full of stars up in front of the other one. I slump down on top of him, he's wriggling underneath me, McConnell is shouting, "Freeze!" and then someone is yelling, too, a small scared voice saying, "Stop, stop." I look up, my vision is wavering back into place, and I say, "Okay." He's got my sidearm, the kid has got it, the service-issue SIG 229, pointed right at my face.

"Son," says McConnell, and she's got her gun out, but she doesn't know what to do with it. She aims it, uncertainly, at Kyle, then at Littlejohn and me, slumped together on the floor, and then back at the boy.

"Let him-" Kyle sniffs, whimpers, and I'm seeing myself, I can't help it, of course, I was eleven once. "Let him go."

G.o.d.

G.o.d, Palace.

You dunce.

The motive was staring me in the face the whole time, not just money but what you can get for it. What you can get for money, even now. Especially now. And here's this funny-looking kid, the wide smile, a princeling, the boy I first saw the second day of my investigation, tromping across a lawn of unbroken snow.

I saw it in Littlejohn's eyes when he was hollering affectionately up the stairs, telling his boy to go ahead and get ready, boasting quietly about what a whiz he is out there on the ice.

Let's say, in our present unfortunate circ.u.mstances, I was the father of a child; what would I not do to s.h.i.+eld that child, to whatever degree I could, from the coming calamity? Depending on where that thing comes down, the world is either ending or descending into darkness, and here is a man who would do anything-who has done awful things-to prolong and protect the life of his child should the latter eventuality arise. To mitigate the hazards of October and after.

And no, Sophia wouldn't have called the police if she had found out, but she would have taken him, taken the boy and gone away, or at least that's what Erik Littlejohn was afraid of-that the mother would not have understood what the father was doing, how important it was, how it had to be done, and she would have s.n.a.t.c.hed him away. And then what would have become of him-and her-in the aftermath?

And tears are welling up and falling from the boy's eyes, and tears are falling from Littlejohn's eyes, and I wish I could say, being a professional detective in the middle of an extraordinarily difficult arrest, that I maintain my composure and focus, but they are, they are, tears are rolling down my face like the flood.

"Give me the gun, young man," I say. "You should give the gun to me. I'm a policeman."

He does. He walks over, and he puts it in my hand.

The little chapel in the bas.e.m.e.nt is stacked with boxes.

They are labeled as containing medical supplies, and, in fact, some of them do: three boxes of syringes, six score to a box, two boxes of protective face masks, a small box of iodine pills and saline solution. IV bags, drip chambers. Tourniquets. Thermometers.

There are pills, too, the same variety I found at the doghouse. Stored here till he had enough to be worth smuggling them out of the hospital and to Toussaint's.

There is food. Five boxes of canned goods: chipped beef and baked beans and chunky soup. Cans like this disappeared many months ago from the supermarket, and you can find them on the black market if you've got the money, but no one has the money. Not even cops. I lift a can of Del Monte pineapple chunks and feel its familiar weight in my hand, comforting and nostalgic.

Most of the boxes, however, are full of guns.

Three Mossberg 817 Bolt Action hunting rifles with twenty-one-inch barrels.

A single Thompson M1 submachine gun, with ten boxes of .45 caliber bullets, fifty bullets in a box.

A Marlin .30-06 with a scope on the top.

Eleven Ruger LCP .380s, little ten-ounce conceal-carry automatic handguns, plenty of ammunition for these, too.

Thousands and thousands and thousands of dollars' worth of guns.

He was just getting ready. Getting ready for afterward. Although, when you look at it from inside this cramped room with the cross on the door, full of boxes of guns and canned foods and pills and syringes, you start to think: well, afterward has started already.

In one long box, of the kind that might have been used to package and s.h.i.+p a vanity mirror or a large picture frame, lies an oversized cross-bow, with ten aluminum bolts tied in a neat bundle at the bottom of the box.

We're in the unit, the suspect is in the backseat, we're on the way back to headquarters. It's a ten-minute drive, but that's time enough. Time enough to know whether I've got the rest of the story straight, or don't I.

Instead of waiting for him to tell me, I tell him, my gaze flicking back and forth to the rear-view mirror, watching Erik Littlejohn's eyes to see if I'm right.

But I am-I know I'm right.

May I please speak to Ms. Naomi Eddes?

That's what he said, that gentle and mellifluous voice, a voice she didn't recognize. It must have been strange, much like the time I called her from Peter Zell's phone. Now here was a strange voice calling from J. T. Toussaint's phone. A number she knew by heart, the number she'd been calling for a few months now, every time she needed to get high, to get lost.

And now the strange voice on the other end began to give her instructions.

Call that cop, said the voice-call your new friend, the detective. Gently remind him of what he's overlooked. Suggest to him that this sordid drug-murder case is about something else entirely.

And boy, did it work. Holy moly. My face burns at the thought of it. My lips curl back in self-disgust.

Insurable interest. False claims. It sounded like just the sort of thing that someone gets killed for, and I dove right in. I was a kid playing a game, overheated, ready to jump for the brightly colored ring dangled in front of me. The dumb detective pacing in excited circles around his house, a fool, a puppy. Insurance fraud! A-ha! That must be it. I need to see what he's working on!

Littlejohn isn't saying anything. He's done. He's living in the future. Surrounded by death. But I know that I'm right.

Kyle has remained at the hospital, sitting in the lobby with Dr. Fenton, of all people, awaiting Sophia Littlejohn, who is now hearing the news, who is about to begin the hardest months of her life. Like everybody else, but worse.

I don't need to ask anymore, I've really got the whole picture, but I can't help it, it can't be helped. "The next day, you came to Merrimack Life and Fire, and you waited, right?"

I linger at a red light at Warren Street. I could blow the light, of course, I have a dangerous suspect in custody, a murderer, but I wait, my hands at ten and two.

"Answer me, please, sir. The next day, you came to her office, and you waited?"

"Yes." A whisper.

"Louder, please."

"Yes."

"You waited in the hallway, outside her cubicle."

"In a closet."

My hands tighten on the wheel, my knuckles white, practically glowing white. McConnell looking at me from the shotgun seat, looking uneasy.

"In a closet. And then when she was alone, Gompers drunk in his office, the rest of them at the Barley House, you showed her the gun, you marched her into the storeroom. Made it look like she was digging for files, too, just to-to what? Turn the screw one more time, for me, make sure I thought what you wanted me to think?"

"Yes, and ..."

"Yes?"

McConnell, I notice, has placed one of her hands over mine, on the wheel, to make sure I don't run off the road.

"She would have told you. Eventually."

Palace, she said, sat on the bed. Something.

"I had to," moans Littlejohn, fresh tears in his eye. "I had to kill her."

"No one has to kill anyone."
