Mma Makutsi proved to be a helpful companion and co-driver. She did not possess a driving licence—not yet—but she took the view that the obtaining of ninety-seven per cent in the final examinations of the Botswana Secretarial College, if not amounting to an actual driving qualification, entitled her to hold views and to advise. So she kept a lookout when Mma Ramotswe wanted to pass something. Now, Mma, right now. Just go a bit faster. There is nothing coming. Go now. She also navigated—which was not an exacting task given that the road to Francistown, which marked the end of the first leg of the journey, ran straight and true from Gaborone northwards and neither meandered nor diverted. “You go straight here, Mma,” said Mma Makutsi. “That sign over there says Francistown. That is the route to take.” Mma Ramotswe nodded. “Yes,” she said. “These are good signs, don’t you think, Mma? They make it quite clear which way you should go.”

Mma Makutsi, interpreting this as veiled criticism of her navigating, searched for an objection to this remark. “But what if there is a blind person?” she challenged. “What use would they be then?”

“But a blind person shouldn’t be driving,” said Mma Ramotswe. And added, as if the matter required further resolution, “That is well known, Mma.”

There could be no answer to that, and the subject of signs was pursued no further. There were other things to talk about, though, and as their conversation wandered this way and that the long miles clocked up. Towns passed, some well known—Mahalapye and Palapye—some small and unimportant to all except those who lived in them, for whom they were everything. Each had associations or memories for Mma Ramotswe, and, to a lesser extent, for Mma Makutsi. One of them would know somebody who came from there, or had relatives there; one of them would know a story that came from that place—a story of envy or overreaching ambition or simple human need.

“That place,” said Mma Makutsi as they drove past a small settlement called Serule. “That is the place where they have discovered uranium. I read about it in the Botswana Daily News. They are going to mine it some day. And then those people living in Serule will have a lot of uranium.”

“I do not want to have any uranium,” said Mma Ramotswe. “They are welcome to it.”

“Of course they won’t keep it. You do not need to keep uranium.”

“There are other things that have happened there,” said Mma Ramotswe. “Apart from finding uranium. I knew a man who came from Serule. He had a sister who did very well at school. High marks … like yours, Mma.”

The compliment pleased Mma Makutsi. She liked people to refer to her results, even if she tried to wear the ninety-seven per cent gracefully. “I see,” she said demurely. “And then?”
