9

According to a certain scientific theory you can only be sure of the existence of what you yourself have experienced. So there must be very few people who are completely convinced that Godthabs Road exists at five o'clock in the morning. At any rate, the windows are dark and empty, the streets are bare, and bus number 2 is empty except for the driver and me.

There's something special about five o'clock in the morning. It's as if sleep touches bottom. The curve of the REM cycle shifts direction and begins to lift the sleeper up toward the recognition that it cannot go on like this much longer. People are as vulnerable as newborn infants at that hour. That's when the big wild animals hunt, and when the police show up to demand payment of delinquent parking fines.

And that's when I take bus number 2 out to Brønshøj, to Kabbeleje Road at the edge of Utterslev Marsh, to pay a visit to forensic medicine expert Lagermann.

He recognized my voice on the phone before I had time to say my name and rattled off a time. "Six-thirty," he said. "Can you make it?"

So I arrive a little before six. People hold their lives together by means of the clock. If you make a slight change, something interesting nearly always happens.

Kabbeleje Road is dark. The houses are dark. The marsh at the end of the street is dark. It's freezing cold, the sidewalk is light gray with frost, the parked cars are covered with a glittering white fur coat. I'll be curious to see the sleepy face of the forensic medicine expert.

There is one house with lights on. Not merely with lights on but illuminated, and with figures moving behind the windows, as if a gala ball has been going on since last night and it's not over yet. I ring the bell. Smilla, the good fairy, the last guest before dawn.

Five people open the door, all at once, and then wedge themselves tightly into the doorway. Five children, from very small to medium-sized. And inside there are more. They're dressed for a raid, with ski boots and backpacks, leaving their hands free to punch somebody. They have milky-white skin, freckles, and copper-red hair under hats with earflaps, and they exude an air of hyperactive vandalism.

Right in the middle stands a woman who has the children's skin and hair color, with the height, shoulders, and back of an American football player. Behind her the forensic medicine expert comes into view.

He's a foot and a half shorter than his wife. He is fully dressed and inveterately red-eyed and chipper.

He doesn't raise an eyebrow at the sight of me. He lowers his head, and we plow our way through the shouts and through some rooms that show signs of barbarian migration, as if the wild hordes had passed this way and back again on their way home; then through a kitchen where sandwiches have been prepared for an entire battalion, and out through a door. He closes the door; it's suddenly quiet, dry, very hot, and there's a purple glow.

We're standing in a greenhouse built onto the house as a kind of winter garden. Except for a couple of narrow pathways, a little terrace with white wrought-iron furniture, and a table, the floor is covered with cactuses in beds and pots. Cactuses of all sizes, from a fraction of an inch up to six feet high. In all stages of prickliness. Lit by ultraviolet grow lights.

"Dallas," he says. "Great place for putting together a collection. Otherwise I don't know whether I'd recommend it; hell if I know. On a Saturday night we could have up to fifty murders. We often had to work downstairs next to the emergency room. It was set up so we could do the autopsies there. It was practical. I learned a lot about gunshot wounds and stab wounds. My wife said I never saw the children. Hell, she was right, too." As he talks, he stares steadily at me.

"You're early, all right. Not that it matters to us; we're up, anyway. My wife got the kids into the nursery school in Allerod. So they could get out in the woods a little. Did you know the little boy?"

"I was a friend of the family. Especially him." We sit down across from each other.

"What do you want?"

"You gave me your card."

He ignores my remark. I sense that he's a man who has seen too much to waste time on pretenses. If he's going to reveal anything, he expects honesty.

So I tell him about Isaiah's fear of heights. About the tracks on the roof. About my visit with Professor Loyen. About Investigator Ravn.

He lights a cigar and looks at his cactuses. Maybe he hasn't understood what I've been telling him. I'm not sure I understand it myself.

"We have the only real institute," he says. "The others have four people fumbling around and they can't even get money for pipettes or for the white mice they need to graft their cell tests on. We have an entire building. We have pathologists and chemists and forensic geneticists. And the whole warehouse in the basement. Teach students, too. And we've got two hundred fucking employees. We get three thousand cases a year. If you're sitting in Odense you might see forty murders. I've had fifteen hundred here in Copenhagen. And just as many in Germany and the United States. There are only maybe three people, tops, in Denmark who can call themselves experts in forensic medicine. Loyen and I are two of them."

Next to his chair there is a cactus that looks like a tree stump in bloom: An explosion of purple and orange has risen out of the languid green, thorny, tree-like growth.

"The morning after the boy was brought in, we were busy. Drunk drivers and Christmas parties. Every afternoon at four o'clock the fucking police are standing there waiting for a report. So at eight o'clock I start on the boy. You're not squeamish, are you? We have a certain routine. First an external examination. We look for cell tissue under the fingernails, for sperm in the rectum, and then we open them up and look at the internal organs."

"Are the police present?"

"Only under unusual circumstances, for instance if there is strong suspicion of murder. Not on this occasion. This was routine. He was wearing rain pants. I hold them up, thinking to myself that they're not what you would wear for doing the long jump. I have a little trick. The kind of thing you invent in any profession. I hold a light bulb inside the pant legs. Helly Hansen. Sturdy stuff. I wear them myself when I work in the garden. But near the thigh there's a perforation. I examine the boy. Purely routine. There I find a hole. I should have noticed it when I was doing the surface examination, I tell you that quite frankly, but what the hell, we're all human. Then I start to frown. Because there wasn't any bleeding, and the tissue hasn't contracted. Do you know what that means?"

"No," I say.

"It means that whatever happened at that spot occurred after his heart stopped beating. Now I take a closer look at his rain gear. There's a little indentation around the hole, and the whole thing rings a bell. So I get out a biopsy needle. A kind of syringe, quite big, attached to a handle. You plunge it into the tissue to get a sample. The way geologists take core samples. Used a lot by sports physiologists over at the August Krogh Institute. And damn if it doesn't fit! The circle on the rain gear could have been caused by someone who was in a hurry, who shoved it in with a good whack."

He leans toward me. "I'll eat my old hat if someone hasn't taken a muscle biopsy from him."

"The ambulance medic?"

"I thought of that, too. It doesn't make any sense, but who the hell else could it be? So I call them up and ask them. I talk to the driver. And the medic. And to our orderlies who received the body. They all swear on a stack of Bibles that they did nothing of the kind."

"Why didn't Loyen tell me this?"

For an instant he seems about to explain. Then the intimacy between us is broken.
