Patrik gave her an incredulous look. Either she was more single- minded than anyone he'd ever met, or she was simply a little crazy. In any case, they needed to put a stop to these idiocies.

'In future we'd appreciate it if you let us do our job. And leave the Wiberg family alone. Is that understood?'

Lilian nodded, but they could see that she was furious. During the whole conversation her friend had watched her with astonishment. Now she made a point of leaving at the same time Patrik and Gösta did. That friendship had no doubt suffered a shock.

They didn't discuss Lilian's story on the way back to the station. The whole thing was much too depressing.

Stig felt a pang of unease as he lay in bed. He knew that Lilian would be angry now, but he didn't quite know what he could have done differently. She had looked completely normal when she came up to his room. He just didn't understand all this nonsense about Kaj assaulting her. Why would she lie about something like that?

The footsteps on the stairs sounded as angry as he had feared. For an instant he wanted to pull the covers over his head and pretend to be asleep, but he thought better of it. Surely it couldn't be such a big deal. He had simply told the truth; Lilian had to realize that. And besides, the whole thing must have been a mistake.

The expression on her face said more than he wanted to know. Evidently she was furious with him, and Stig literally cringed under her gaze. He always found it extremely unpleasant when she was in one of these moods. He couldn't understand how someone like his Lilian, who was so amiable and warm, could occasionally be transformed into such a disagreeable person. Suddenly he wondered whether what the police had hinted at really might be true. Had she made up an accusation against Kaj? But he dismissed the idea. They just needed to straighten out this misunderstanding, and then he would grasp the situation.

'Can't you ever keep your big mouth shut?' She loomed over him, and her sharp tone of voice sent lightning bolts through his head.

'But my dear, I only told -'

'The truth? Is that what you wanted to say? That you simply told them the truth? How fortunate we all are to have such upright people as you, Stig. Honest, honourable people who don't give a damn whether they put their own wife in jeopardy. I thought you were supposed to be on my side.'

He felt saliva spray across his face and hardly recognized the distorted face hovering above him.

'But I'm always on your side, Lilian. I just didn't know…'

'Didn't know? Do I have to spell out everything for you, you stupid idiot?'

'But you didn't say anything to me… and the police are probably just imagining the whole absurd thing. I mean, you wouldn't make up things like that, would you?' Stig was struggling bravely to find some sort of logic in the rage that was directed at him. Only now did he notice the mark on Lilian's face that was starting to take on a purplish hue. His eyes narrowed and he gave her a searching look.

'What's that mark you have on your face, Lilian? You didn't have it when you came up to see me. Are you saying that what the police hinted at was right? Did you make up a story about Kaj hitting you when he was here?' His voice was incredulous, but he saw Lilian's shoulders droop a bit and needed no further confirmation.

'Why on earth would you do something so stupid?' Now their roles were reversed. Stig's voice was sharp, and Lilian sank down on the edge of the bed, burying her face in her hands.

'I don't know, Stig. I can see now that it was stupid, but I wanted them to start looking at Kaj and his family seriously. I'm positive that somehow they're mixed up in Sara's death. Haven't I always told you that man is totally lacking in scruples? And that weird Morgan, sneaking about in the bushes and spying on me. Why don't the police do something?'

Her body was shaking with sobs, and Stig summoned his last strength to sit up in bed despite the pain and put his arms around his wife. He stroked her back reassuringly, but his eyes were restless and searching.

When Patrik came home, Erica was sitting alone in the dark, thinking. Kristina had taken Maja out for a walk, and Charlotte had long since gone home. What Charlotte had said was worrying her.

When Erica heard Patrik open the front door she got up and went to meet him.

'Why are you sitting here in the dark?' He set a couple of grocery bags on the counter and began turning on lamps. The glare blinded her for a second before she got used to it. Then she sat down heavily at the kitchen table and watched her husband as he unpacked what he had bought.

'How pleasant things are here at home,' he said cheerfully, looking around. 'It certainly is nice that Mamma can come by and help out occasionally,' he went on, unaware that Erica was giving him the evil eye.

'Oh yes, it's just peachy,' she said acidly. 'It must be wonderful to come home to a clean and well-organized home for a change.'

'Yeah, it sure is!' said Patrik, still clueless that he was digging his own grave deeper with each passing second.

'Then maybe you should see about staying home in future, so things will be more orderly around here!' Erica yelled.

Patrik jumped from her sudden increase in volume. He turned round with an astonished look on his face.

'What did I say now?'

Erica got up from her chair and stormed out. Sometimes he was too stupid for words. If he didn't get it, she didn't have the energy to explain.

She sat down again in the dim light of the living room and looked out of the window. The weather outside precisely reflected how she felt inside. Grey, stormy, raw and cold. Deceptively calm periods with occasional strong storms. Tears began running down her cheeks. Patrik came and sat down beside her on the sofa.

'I'm sorry for being so dumb. It must not be that easy to have Mamma here in the house, is it?'

She could feel her lower lip quivering. She was so tired of crying. She felt she hadn't done anything else these past few months. If only she'd been prepared for how it would be. The contrast was so great to the joy she'd always believed she would feel when she had a baby. In her darkest moments she almost hated Patrik because he didn't feel the same way she did. The rational part of her was relieved because someone had to keep the family going. But she wished that for just a moment he could put himself in her situation and understand how she felt.

As if he was able to read her thoughts he said, 'I wish I could change places with you, I really do. But I can't, so you have to stop being so bloody brave and tell me what's going on with you. Maybe you should even go and talk with someone else, a professional. The people at the child care centre could probably help us out.'

Erica shook her head. Her depression would surely pass of its own accord. It had to. Besides, there were women who had it much worse than she did.

'Charlotte stopped by today,' she said.

'How's she doing?' Patrik said quietly.

'Better, whatever that means.' She paused. 'Are you getting anywhere?'

Patrik leaned back in the sofa and looked up at the ceiling. He heaved a deep sigh and said, 'No, unfortunately. We hardly know where to start. And besides, Charlotte's screwy mother seems to be more interested in finding more ammunition for her feud with her neighbour than in helping us with the investigation. It hasn't made our work any easier.'

'What's that all about?' Erica asked with interest. Patrik gave her a brief rundown of the day's events.

'Do you really think anyone in Sara's family could have had anything to do with her death?' Erica asked.

'No, I have a hard time believing that,' said Patrik. 'They all have plausible alibis for where they were that morning.'

'They do?' said Erica in an odd tone of voice. Patrik was about to ask what she meant when they heard the front door open and Kristina came in with Maja in her arms.
