“Fifteen,” corrected Mma Mateleke, in a rather school-marmish way. “She had fifteen, and now has fourteen. And no husband, by the way. All the children are by different fathers.”

Mr. J.L.B. Matekoni shook his head. “That is very wrong,” he said.

“Yes,” agreed Mma Mateleke. “What happened to marriage, Mr. J.L.B. Matekoni?”

“I am married,” he said. “I am very much in favour of it.” He paused. He was thinking of what he had witnessed at the site of the breakdown. What was that man-Mr. Ntirang or whatever he was called-what was he doing coming down to see that Mma Mateleke was all right? He recalled what he had imagined Mma Ramotswe might have said, had he told her about Mr. Ntirang’s bad driving: That man is having an affair. Was he? Was that why he was rushing down to Lobatse, to meet his lover-none other than Mma Mateleke?

He glanced at Mma Mateleke, sitting beside him. She was an attractive woman, he decided, although an unduly talkative woman would never have appealed to him personally. Yet there were some men who liked that sort of woman, who got nothing but pleasure from listening to the incessant chatter of their wife or girlfriend. Some men even found that exciting in a physical way… He bit his lip. He could not imagine being interested in that way in somebody like Mma Mateleke; how would one ever get to plant a kiss on such a person if she was always talking? It would be difficult to get one’s lips into contact with a mouth that was always opening and shutting to form words; that would surely be very distracting for a man, he thought, and might even discourage him to the point of disinclination, if that was the right word. But it did not do to think about these things, he felt; it was no business of his whether or not Mma Mateleke was having an affair with Mr. Ntirang, and this was not even altered by the fact that she was married-apparently happily-to a part-time reverend, of all people. This reverend was popular and highly thought of, and even broadcast every now and then on Radio Botswana, when he would talk on a programme called From the Pulpit. It is no business of mine, thought Mr. J.L.B. Matekoni; my business is to fix cars, just as it is Mma Mateleke’s business to bring babies into the world.

No, it was none of his business to speculate, but he could still ask Mma Mateleke how her husband was, which he did, and she replied, “My husband is in very good health, thank you, Rra.”

The answer came quickly, and Mr. J.L.B. Matekoni found himself wondering whether it was not perhaps a little bit on the dismissive side, as if she wished to preclude any further discussion of the reverend. The words thank you can sometimes be uttered in that way, meaning No further discussion, please, as in: I am quite all right, thank you very much.

“I am glad to hear that he is well,” he said. “That is good.”

“Yes,” said Mma Mateleke. “That is good.”

There was a silence. Mr. J.L.B. Matekoni took the opportunity to wind down the window on the driver’s side. Then he said, “He must be very busy. A popular reverend is always busy, isn’t he? Even if he is part-time.”

Mma Mateleke nodded. She was looking out of the window on her side. “There is always something happening,” she said. “People forget that he is part-time, and that he has a business to run as well. They get married and die and do all these things that need reverends. And he has to think about what he is going to say in his sermons on the radio. That is very hard work, of course, because you cannot go on the radio and say any old thing, can you?”

He shook his head. “That is very true. You cannot say the first thing in your mind when you know that the whole country is listening.”

“If it’s listening,” said Mma Mateleke. “I think there are many people who turn off the radio when my husband’s programme comes on.”

Mr. J.L.B. Matekoni frowned. This was a strange thing for a wife to say; surely if one’s spouse was on the radio one should be a bit more loyal in one’s remarks. It was a very odd remark, but he decided to make light of it. “Those will be the bad people,” he said. “Bad people do not like to listen to reverends on the radio. They make them feel guilty. So all the bad people turn off at the same time-click, click, click.”

He looked at her sideways, expecting her to laugh, or at least smile, at his observation. But she did not. She was looking out of the window again, and he was not sure that she had heard him.

“It is his birthday next week,” she said suddenly. “I shall make him a very special cake. He is turning forty, you see, and I am planning a special party for him.”

Mr. J.L.B. Matekoni felt relieved. That settled that, he thought. If Mma Mateleke were having an affair, then she would hardly be talking about making a special effort for her husband’s birthday. This was not the way a woman in that situation behaved. He felt guilty about his suspicions; if everybody who saw a married woman talking to a strange man were to draw the conclusion that there was something going on, then ordinary life would become quite impossible. He would be unable to talk to Mma Makutsi, for example, and she to him. And Mma Ramotswe would be unable to talk to the apprentices-especially Charlie, whom any husband might very readily assume was up to no good, with those shoes of his and the sunglasses that he affected, even on an overcast day and, as Mr. J.L.B. Matekoni had once observed, at night. No, there was nothing at all to justify any suspicions, and he should stop thinking this way. And yet… why had Mma Mateleke’s friend changed course so readily from Lobatse to Gaborone? No matter which way he looked at it, that did not make sense. He would talk to Mma Ramotswe; she knew about these things, and if there was an innocent explanation-which surely there must be-she could be expected to find it.

AS MR. J.L.B. MATEKONI was driving Mma Mateleke and her unresponsive car back to Gaborone, in the offices of the No. 1 Ladies’ Detective Agency Mma Makutsi, assistant detective and graduate summa cum laude of the Botswana Secretarial College, was busy making the mid-morning tea. As usual, she was preparing red bush tea for her employer and ordinary tea for herself, using a special teapot for each purpose. The two teapots were the same colour, an indeterminate brown, but there was a distinguishing feature: Mma Ramotswe’s teapot was considerably larger. Mma Makutsi, who had been used all her life to having very little, and accepted this with the quiet resignation that such people often possess, had never questioned this arrangement. Mma Ramotswe was, after all, the proprietor of the agency, and the owner of both pots. But she had recently asked herself whether it would not make more sense for the red bush tea, which was required in smaller quantities, to be brewed in the smaller teapot, while the ordinary tea might be made in the larger pot, since it was not only for her own consumption, but was also drunk by Mr. J.L.B. Matekoni, by his unqualified assistant, Mr. Polopetsi, and by the two apprentices, Charlie and Fanwell. It was unusual for all of these to present themselves for tea at the same time, but it sometimes did happen. Then it was necessary for Mma Makutsi to brew another pot, while the resources of Mma Ramotswe’s commodious teapot were barely called upon.

She had been silent, but now she decided to broach the subject. At the Botswana Secretarial College, where she had obtained the hitherto unheard-of result of ninety-seven per cent in the final examinations, Mma Makutsi had been taught that it was always better to raise issues of office procedure rather than to brood over them. “There is nothing worse, ladies, than muttering about something,” said the lecturer. “If something is wrong, then raise it. Not only is that better for you-nursing a grudge makes you far less efficient in your work-but it is also much better for your boss. So spit it out, and always remember this: a problem shared is a problem solved.” Or had she said, A problem shared is a problem halved? It was difficult to remember these things when there were so many proverbs jostling to give advice. Locusts do not land only on the land that belongs to your neighbour. The person who lies by the fire knows how hot it is… And so on; all of these sayings were undoubtedly true, but might still quite easily be forgotten-until the moment you found yourself doing exactly the thing that the proverb warned you against.
