“That is the doctor’s mother,” said Mrs. Moffat.

“And this person standing behind them? This man who is looking at the camera?”

“That is somebody who comes to stay with us from time to time,” said Mrs. Moffat. “He writes books.”

Mma Ramotswe examined the photograph more closely. “It seems that he is looking at me,” she said. “He is smiling at me.”

“Yes,” said Mrs. Moffat. “Maybe he is.”

Mma Ramotswe looked again at the photograph of her father which Mrs. Moffat had given to her. Yes, that was his smile; hesitant at first, and then broader and broader; and his hat, of course… She wondered what the occasion had been, why these people were standing outside the gate of the kgotla, the meeting place; the doctor would know, perhaps, as he must have taken the photograph. Perhaps it was something to do with the hospital; people raised money for it and had meetings about it. That might have been it.

Everybody in the photograph was smartly dressed, even under the sun, and everybody was looking at the camera with courtesy, with an attitude of moral attention. That was the old Botswana way-to deal with others in this way-and that was passing, was it not, just as the world and the people captured in this photograph were passing. She touched the photograph with her finger, briefly, as if to communicate with, to touch, those in it, and as she did so, she felt her eyes fill with tears.

“Please excuse me, Mma,” she said to Mrs. Moffat. “I am thinking of how this old Botswana is going away.”

“I understand,” said Mrs. Moffat, reaching out for her friend’s arm. “But we remember it, don’t we?” And she thought, yes, this woman, this daughter of Obed Ramotswe, whom everybody agreed was a good man, would remember things about the old Botswana, about that country that had been-and still was-a beacon of light in Africa, a country of integrity and generosity in both the simple and the big things.

THAT EVENING the typing class went particularly well. Mma Makutsi had planned a test for her students, to determine their speed, and had been pleasantly surprised by the results. One or two of the men were not very good-indeed, one of them was talking about giving up but had been persuaded by the other members of the class to persist. Most, however, had worked hard and were beginning to feel the benefits of practice and the expert tuition provided by Mma Makutsi. Mr. Bernard Selelipeng was doing particularly well and, entirely on the basis of merit, had attained the highest words-per-minute score in the class.

“Very good, Mr. Selelipeng,” said Mma Makutsi as she looked at his score. She was determined to keep their professional relationship formal, although as she spoke to him, she felt a warm flush of feeling for this man who treated her with such respect and admiration. And he, in turn, treated her as his teacher, not as his girlfriend; there was no familiarity, no assumption that he would be given special treatment.

After the class ended and she had locked the hall, Mma Makutsi went outside and found him, as they had agreed, sitting in his car, waiting for her. He suggested that they go to the cinema that evening, and afterwards to a café for something to eat. This idea appealed to Mma Makutsi, who relished the thought that rather than going to the cinema by herself, as was often her lot, she would this time be sitting with a man, like most of the other women.

The film was full of silly, rich people living in conditions of unimaginable luxury, but Mma Makutsi was barely interested in it and scarcely followed what was happening on screen. Her thoughts were with Mr. Bernard Selelipeng, who, halfway through the performance, slipped his hand into hers and whispered something heady into her ear. She felt excited and happy. Romance had arrived in her life at last, after all these years and all that waiting; a man had come to her and given her life a new meaning. That impression-or delusion-so common to lovers, of personal transformation, was strong upon her, and she closed her eyes at the sheer pleasure and happiness of it all. She would make him happy, this man who was so kind to her.

They went to a café after the cinema and ordered a meal. Then, sitting at a table near the door, they talked about one another, as lovers do, their hands joined under the table. That is where they were when Mma Ramotswe came in, with Mr. J.L.B. Matekoni. Mma Makutsi introduced her friend to Mma Ramotswe, who smiled and greeted him politely.

Mma Ramotswe and Mr. J.L.B. Matekoni did not stay long in the café.

“You are upset about something,” said Mr. J.L.B. Matekoni to Mma Ramotswe as they made their way back to the van.

“I am very sad,” said Mma Ramotswe. “I have found something out. But I am too upset to talk about it. Please drive me back to my house, Mr. J.L.B. Matekoni. I am very sad.”

YES, THOUGHT Mma Ramotswe, the world can be very discouraging. But we cannot sit and think about all the things that have gone wrong, or could go wrong. There was no point in doing that because it only made things worse. There was much for which we could be grateful, whatever the sorrows of this world. Besides, dwelling on the trials and tribulations of life was time-consuming, and ordinary duties still have to be performed; livings have to be earned, and in the case of Mma Ramotswe, this meant that she had to do something about Mr. Molefelo and his conscience. It was over a week since she had found Mma Tsolamosese, which had been the easy part; now she had to find Tebogo, the girl who had been so badly treated by Mr. Molefelo.

The information she had was slender, but if Tebogo had become a nurse, then she would have been registered, and might be registered still. That would be a starting point, and then, if Mma Ramotswe found nothing there, she still had various other lines of enquiry. Tebogo had come from Molepolole, Mma Ramotswe had been told. She could go there and find somebody who knew the family.

It did not take her long to exhaust the nursing route. Once she had found the civil servant in charge of nurse training, it had been easy to ascertain whether anybody of that name had been registered as a nurse in Botswana. There had not, which meant that Tebogo had either not trained or, having been trained, had not completed her registration. Mma Ramotswe was thoughtful; it might be that the consequences of Tebogo’s involvement with Mr. Molefelo had had much greater repercussions for her life than she had imagined. People’s lives are delicate; you cannot interfere with them without running the risk of changing them profoundly. A chance remark, a careless involvement, may make the difference between a life of happiness and one of sorrow.

A trip out to Molepolole would not be unwelcome and would give Mma Ramotswe the chance to speak to several old friends whom she knew out there. One, in particular, a retired bankteller, knew everybody in the town and would be able to tell her about Tebogo’s family. Perhaps Tebogo herself would be living there now, and Mma Ramotswe would be able to visit her. That would require tact, particularly if she was married. She might not have told her husband about the baby, and men can be possessive and unreasonable about these things. They, of course, did not have to bear the children; they did not have to carry the babies around on their backs for the first few years; they did not have to attend to the daily, hourly, minute-by-minute needs of the baby, and yet they could have very strong views on the subject of babies.

She chose a fine morning for the trip out to Molepolole, a morning when the air was crisp and clean and the sun not too hot. As she drove, she thought of the events of the last few days, and in particular of the disturbing discovery she had made of Mma Makutsi’s involvement with Mr. Bernard Selelipeng. She had been shocked by what she had found out, and the following morning her dismay had been compounded when Mma Makutsi had talked at some length about Mr. Selelipeng and about how well suited they were.
