Søren tried to break all this information into bite-size pieces.
“Go on,” he said, brusquely.
“I spent almost two hours with Professor Moritzen today. That’s why I couldn’t wait for you and I didn’t answer my cell. I had to see her. Hanne is my friend, and she lied. She has a son! I was really angry when I got there, but she… she told me everything. She has known all weekend that Asger killed Helland. She wanted to go to the police, but… mothers and their children,” Anna suddenly burst out. “Mothers will do anything to protect their children.”
Søren was about to say something when she continued.
“I promised Hanne you’ll take good care of him when you pick him up. Asger’s mentally frail, but not dangerous, she assured me. I think he’s mostly scared.”
Søren swallowed.
“So you know where Dr. Tybjerg is?” he said.
“Yes,” Anna said. “I’ve known all the time. Sorry.”
“Why didn’t you tell me?” Søren said, angrily.
“Dr. Tybjerg is on the verge of a breakdown, so I couldn’t run the risk. I want to have my dissertation defense next Monday. I have to get it over and done with. I have a three-year-old daughter. I have to become her mother again.”
“So where is he?” Søren said, appeased.
“I’ll tell you later.” Anna’s voice was calm. “Tomorrow. But I can’t be with you at ten. There’s something I have to do first. I’ll be there at one. And now I’ve got to go.”
“Anna, I demand to know where Dr. Tybjerg is!”
“Trust me.”
And she was gone.
Søren sat at his desk, staring at the telephone.
Søren went to visit Professor Moritzen.
“Come in,” she said, hoarsely, buzzing him in. She was wearing a soft gray outfit and was waiting for him in the doorway when he came up the stairs. Her hair was wet as though she had just had a shower.
They sat down in the living room. Like her vacation cottage, her apartment was carefully furnished, limited to bamboo and white, broken only by splashes of bright red and orange. Professor Moritzen perched on the edge of the sofa and waited for Søren to begin.
“I’m here because Anna Bella Nor called me an hour ago and told me—”
“I asked her to call you,” Professor Moritzen interrupted him.
“So you suspect your son, Asger Moritzen, infected Professor Helland with parasites?” he said.
She nodded.
“And the late Lars Helland was your son’s biological father?”
She nodded again.
“Why do you think your son infected his father with parasites?” Søren wondered if Professor Moritzen was mentally ill. Did she even have a son or was she making it all up?
“Asger told me last Thursday,” she said. “He was very scared, but he felt better after telling me. When will you be picking him up?” She looked beseechingly at Søren. “Asger is very delicate. You can’t just barge in on him. You need to go there, alone, and talk to him. You won’t just barge in, will you?” she repeated. “He has dangerous bugs and reptiles in there,” she added.
“In his apartment?” Søren frowned.
“Yes, he has tanks full of them,” she replied. “So, are you going to get him?”
“When did you last speak with him?”
“Perhaps you could just let me tell you the whole story,” she said.
Chapter 18
“Asger’s a good boy,” she said and didn’t seem to have heard his question. “Please don’t hurt him. He didn’t mean to kill Lars…. The silly boy thought he had given his father a tapeworm. A tapeworm! He just wanted to annoy him a little, but he didn’t mean to kill him, of course he didn’t. But you don’t get a tapeworm from eating a piece of one! And you don’t get a tapeworm infection from eating its eggs, either! Stupid boy.” Her voice became shrill. “I’m a parasitologist, and my own son commits such a howler. And he’s a biologist, too.” Professor Moritzen looked mortified.
“At least you know where the 2,600 cysticerci came from,” she added, dryly. “From my silly boy. Of course, I wondered how Asger got ahold of the material, and I’ve discovered that…. There was one weekend in May when my keys went missing and I had to use my spare set. My keys reappeared and I thought nothing of it. Asger had let himself into my lab and took the tapeworm from the in-vitro supply. I honestly believed I knew precisely how many specimens I have. After all, I count them. But he had only taken one and when I checked, it seemed to add up to me.” She gestured apologetically. “I have samples in cold storage, for dissection, and I have living specimens, which are kept in artificial conditions, like the ones found in the small intestines. At least he had been smart enough to take a living specimen, but his knowledge stopped there,” she said bitterly. “That Monday he went to the department of Cell Biology and Comparative Zoology to have lunch with Professor Ewald in her office across from the senior common room. They know each other from a project when Asger was still an undergraduate. At some point, Asger went to fetch some salt, and while he was in the senior common room he opened the fridge and placed the tapeworm segment in Lars’s lunch.”
“How did he know the food belonged to Lars Helland?” Søren interjected.
Professor Moritzen sighed.
“The stupid idiot had planned it all down to the last detail. He had gone to the senior common room twice the previous week. On both occasions, he had found an empty cool bag with the initials L.H. and once when Asger passed the senior common room, he had seen Lars eat leftovers from it. He was very careful. He certainly didn’t want to infect Professor Jørgensen or Professor Ewald. Asger was angry. I told him Lars Helland was his father shortly after I was told I would be laid off. I had always told Asger he was the result of a one-night stand and that I knew nothing about his father. But I was in love with Lars and got pregnant by him during my second year as an undergraduate. Lars was already married to Birgit, and he was shocked when I confronted him. He told me he didn’t believe the child was his. But I knew it was. We reached an impasse and people started talking. Someone had seen us together, and now I was pregnant. Lars got completely paranoid and offered me money. He would have been fired on the spot had it become known that he had got an undergraduate pregnant. I accepted his offer. I moved to Århus and had Asger. Lars bought us an apartment on the condition that I signed a document stating he wasn’t Asger’s father. I listed my son’s father as ‘unknown,’ and, to be honest, I forgot all about him. I was twenty years old, I lived in Århus, and was busy with my studies and my little boy. I met other men. Do you want some tea?”
Søren nodded and Professor Moritzen disappeared into the kitchen. Shortly afterward, she returned with a small bowl with steaming contents, which she handed to Søren. She sat down on the sofa and blew carefully into her own bowl.
“After all those years why did you decide to tell Asger that Professor Helland was his father?”
Professor Moritzen heaved another sigh.
“Asger grew up without a father, but it was never a problem. When he turned nineteen, he decided he wanted to study biology. To begin with, I was dead set against it. An academic career isn’t for the faint of heart. It’s one long uphill struggle. For money, for recognition, for elbow room. I genuinely doubted if Asger was cut out for it. He’s a loner, wary and ultra-sensitive. But he was adamant. He had followed my work his whole life, and when he wanted a butterfly net for Christmas and an aquarium for his birthday that’s what he got. I don’t know why I expected anything else.” She shook her head. “In 1998 I applied for the post of professor of parasitology at the University of Copenhagen, never thinking for one minute I would get it. But halfway through the summer break, I got a phone call. The job was mine. Less than a week later Asger got a letter. He was offered a place to read biology at the University of Copenhagen. That summer we moved. I sold the apartment in Århus and bought two apartments with the money; this one and the one Asger lives in, on Glasvej.
