Mr J.L.B. Matekoni sensed that something was wrong. He had come to dinner, to tell her of his visit earlier that evening to his maid in prison, and had immediately noticed that she seemed distracted. He did not mention it at first; there was a story to tell about the maid, and this, he thought, might take Mma Ramotswe's mind off whatever it was that was preoccupying her.
"I have arranged for a lawyer to see her," he said. "There is a man in town who knows about this sort of case. I have arranged for him to go and see her in her cell and to speak for her in court."
Mma Ramotswe piled an ample helping of beans on Mr J.L.B. Matekoni's plate.
"Did she explain anything?" she asked. "It can't look good for her. Silly woman."
Mr J.L.B. Matekoni frowned. "She was hysterical when I first arrived. She started to shout at the guards. It was very embarrassing for me. They said: 'Please control your wife and tell her to keep her big mouth shut.' I had to tell them twice that she was not my wife."
"But why was she shouting?" asked Mma Ramotswe. "Surely she understands that she can't shout her way out of there."
"She knows that, I think," said Mr J.L.B. Matekoni. "She was shouting because she was so cross. She said that somebody else should be there, not her. She mentioned your name for some reason."
Mma Ramotswe placed the beans on her own plate. "Me? What have I got to do with this?"
"I asked her that," Mr J.L.B. Matekoni went on. "But she just shook her head and said nothing more about it."
"And the gun? Did she explain the gun?"
"She said that the gun didn't belong to her. She said that it belonged to a boyfriend and that he was coming to collect it. Then she said that she didn't know that it was there. She thought the parcel contained meat. Or so she claims."
Mma Ramotswe shook her head. "They won't believe that. If they did, then would they ever be able to convict anybody found in possession of an illegal weapon?"
"That's what the lawyer said to me over the telephone," said Mr J.L.B. Matekoni. "He said that it was very hard to get somebody off one of these charges. The courts just don't believe them if they say that they didn't know there was a gun They assume that they are lying and they send them to prison for at least a year. If they have previous convictions, and there usually are, then it can be much longer."
Mma Ramotswe raised her teacup to her lips. She liked to drink tea with her meals, and she had a special cup for the purpose. She would try to buy a matching one for Mr J.L.B. Matekoni, she thought, but it might be difficult, as this cup had been made in England and was very special.
Mr J.L.B. Matekoni looked sideways at Mma Ramotswe. There was something on her mind. In a marriage, he thought, it would be important not to keep anything from one's spouse, and they might as well start that policy now. Mind you, he recalled that he had just kept the knowledge of two foster children from Mma Ramotswe, which was hardly a minor matter, but that was over now and a new policy could begin.
"Mma Ramotswe," he ventured. "You are uneasy tonight. Is it something I have said?"
She put down her teacup, glancing at her watch as she did so.
"It's nothing to do with you," she said. "I have to go and speak to somebody tonight. It's about Mma Curtin's son. I am worried about this person I have to see."
She told him of her fears. She explained that although she knew that it was highly unlikely that an economist at the University of Botswana would turn to violence, nonetheless she felt convinced of the evil in his character, and this made her profoundly uneasy.
"There is a word for this sort of person," she explained. "I read about them. He is called a psychopath. He is a man with no morality."
He listened quietly, his brow furrowed with concern. Then, when she had finished speaking, he said: "You cannot go. I cannot have my future wife walking into danger like that."
She looked at him. "It makes me very pleased to know that you are worried about me," she said. "But I have my calling, which is that of a private detective. If I was going to be frightened, I should have done something else."
Mr J.L.B. Matekoni looked unhappy. "You do not know this man. You cannot go to his house, just like that. If you insist, then I shall come too. I shall wait outside. He need not know I am there."
Mma Ramotswe pondered. She did not want Mr J.L.B. Matekoni to fret, and if his presence outside would relieve his anxiety, then there was no reason why he should not come.
"Very well," she said. "You wait outside. We'll take my van. You can sit there while I am talking to him."
"And if there is any emergency," he said, "you can shout. I shall be listening."
They both finished the meal in a more relaxed frame of mind. Motholeli was reading to her brother in his bedroom, the children having had their evening meal earlier. Dinner over, while Mr J.L.B. Matekoni took the plates through to the kitchen, Mma Ramotswe went down the corridor to find the girl half-asleep herself, the book resting on her knee. Puso was still awake, but drowsy, one arm across his chest, the other hanging down over the edge of the bed. She moved his arm back onto the bed and he smiled at her sleepily.
"It is time for you to go to bed too," she said to the girl. "Mr J.L.B. Matekoni tells me that you have had a busy day repairing engines."
She wheeled Motholeli back to her own room, where she helped her out of the chair and onto the side of the bed. She liked to have her independence, and so she allowed her to undress herself unaided and to get into the new nightgown that Mr J.L.B. Matekoni had bought for her on the shopping trip. It was the wrong colour, thought Mma Ramotswe, but then it had been chosen by a man, who could not be expected to know about these things.
"Are you happy here, Motholeli?" she asked.
"I am so happy," said the girl. "And every day my life is getting happier."
Mma Ramotswe tucked the sheet about her and planted a kiss on her cheek. Then she turned out the light and left the room. Every day I am getting happier. Mma Ramotswe wondered whether the world which this girl and her brother would inherit would be better than the world in which she and Mr J.L.B. Matekoni had grown up. They had grown happier, she thought, because they had seen Africa become independent and take its own steps in the world. But what a troubled adolescence the continent had experienced, with its vainglorious dictators and their corrupt bureaucracies. And all the time, African people were simply trying to lead decent lives in the midst of all the turmoil and disappointment. Did the people who made all the decisions in this world, the powerful people in places like Washington and London, know about people like Motholeli and Puso? Or care? She was sure that they would care, if only they knew. Sometimes she thought that people overseas had no room in their heart for Africa, because nobody had ever told them that African people were just the same as they were. They simply did not know about people like her Daddy, Obed Ramotswe, who stood, proudly attired in his shiny suit, in the photograph in her living room.
You had no grandchildren, she said to the photograph, but now you have. Two. In this house.
The photograph was mute. He would have loved to have met the children, she thought. He would have been a good grandfather, who would have shown them the old Botswana morality and brought them to an understanding of what it is to live an honourable life. She would have to do that now; she and Mr J.L.B. Matekoni. One day soon she would drive out to the orphan farm and thank Mma Silvia Potokwane for giving them the children. She would also thank her for everything that she did for all those other orphans, because, she suspected, nobody ever thanked her for that. Bossy as Mma Potokwane might be, she was a matron, and it was a matron's job to be like that, just as detectives should be nosy, and mechanics... Well, what should mechanics be? Greasy? No, greasy was not quite right. She would have to think further about that.
