The tenth book in the No 1 Ladies Detective agency series, 2009

TRADITIONALLY BUILT PEOPLE may not look as if they are great walkers, but there was a time when Precious Ramotswe walked four miles a day. As a girl in Mochudi, all those years ago, a pupil at the school that looked down over the sprawling village below, she went to her lessons every morning on foot, joining the trickle of children that made its way up the hill, the girls in blue tunics, the boys in khaki shirts and shorts, like little soldiers. The journey from the house where she lived with her father and the older cousin who looked after her took all of an hour, except, of course, when she was lucky and managed to ride on the mule-drawn water cart that occasionally passed that way. The driver of this cart, with whom her father had worked in the gold mines as a young man, knew who she was and always slowed down to allow her to clamber up on the driver's seat beside him.

Other children would watch enviously and try to wave down the water cart. “I cannot carry all Botswana,” said the driver. “If I gave all you children a ride on my cart, then my poor mules would die. Their hearts would burst. I cannot allow that.”

“But you have Precious up there!” called out the boys. “Why is she so special?”

The driver looked at Precious and winked. “Tell them why you are special, Precious. Explain it to them.”

The young Mma Ramotswe, barely eight, was overwhelmed by embarrassment.

“But I am not special. I am just a girl.”

“You are the daughter of Obed Ramotswe,” said the driver. “He is a great man. That is why you are riding up here.”

He was right, of course-at least in what he said about Obed Ramotswe, who was, by any standards, a fine man. At that age, Precious had only a faint inkling of what her father stood for; later on, as a young woman, she would come to understand what it was to be the daughter of Obed Ramotswe. But in those days, on the way to school, whether riding in state on the water cart or walking along the side of that dusty road with her friends, she had school to think about, with its lessons on so many subjects-the history of Botswana, from the beginning, when it was known as Khama's country, across the plains of which great lions walked, to the emergence of the new Botswana, then still a chrysalis in a dangerous world; writing lessons, with the letters of the alphabet being described in white chalk on an ancient blackboard, all whirls and loops; arithmetic, with its puzzling multiplication tables that needed to be learned by heart-when there was so much else that the heart had to learn.

The water cart, of course, did not pass very often, and so on most days there was a long trudge to school and a long walk back. Some children had an even greater journey; in one class there was a boy who walked seven miles there and seven miles back, even in the hottest of months, when the sun came down upon Botswana like a pounding fist, when the cattle huddled together under the umbrella shade of the acacia trees, not daring to wander off in search of what scraps of grass remained. This boy thought nothing of his daily journey; this is what you did if you wanted to go to school to learn the things that your parents had never had the chance to learn. And you did not complain, even if during the rainy season you might narrowly escape being struck by lightning or being washed away by the torrents that rose in the previously dry watercourses. You did not complain in that Botswana.

Now, of course, it was different, and it was the contemplation of these differences that made Mma Ramotswe think about walking again.

“We are becoming lazy, Mma Ramotswe,” said Mma Makutsi one afternoon, as they sipped their afternoon cup of red bush tea in the offices of the No. 1 Ladies' Detective Agency. “Have you noticed? We are becoming lazy.”

Mma Ramotswe frowned. There were times when Mma Makutsi made statements that suffered from that classic flaw of all generalisations-they were just too general. This observation, it seemed to her, could be such a remark.

“Do you mean that you and I are becoming lazy?” she asked her assistant. “If you do, then I do not think that's right, Mma Makutsi. Take this morning, for instance. We finished that report on security at the loan office. And we wrote a lot of letters. Six, seven, I think. That is not being lazy.”

Mma Makutsi raised a hand in protest. “No, Mma, I did not mean that. I did not mean to say that you and I are becoming lazy. Or not specially lazy. I am talking about everybody.”

Mma Ramotswe raised an eyebrow. “The whole of Botswana?”

Mma Makutsi nodded. “Yes, the whole country. And it's not just Botswana, Mma. We are no worse than anybody else. In fact, I am sure that there are many much lazier countries elsewhere. What I really meant was that people in general are becoming lazy.”

Mma Ramotswe, who had been prepared to defend Botswana against Mma Makutsi's accusations, relaxed. If the remark was about people in general, and not just about the residents of Gaborone, then Mma Makutsi's theory could at least be heard out. “Why do you say that people are becoming lazy, Mma?” she asked.

Mma Makutsi glanced through the half-open door that led from the agency into the garage. On the other side of the workshop, Mr. J.L.B. Matekoni was showing his two apprentices an engine part. “You see those two boys out there?” she said. “Charlie and…”

“Fanwell,” supplied Mma Ramotswe. “We must start using his name. It is not kind to be forgetting it all the time.”

“Yes, Charlie and… Fanwell,” said Mma Makutsi. “It is a stupid name, though, don't you think, Mma? Why would anybody be called Fanwell?”

Mma Ramotswe could not let this pass. Mma Makutsi was too hard on the two apprentices, particularly on the older one, Charlie. Words had passed between them more than once, including on the occasion when Charlie had called Mma Makutsi a warthog and made disparaging references to her large glasses. It had been quite wrong of him, and Mma Ramotswe had made that plain, but she had also acknowledged that he had been provoked. “They are young men,” she had said to Mma Makutsi. “That is what young men are like, Mma. Their heads are full of loud music and thoughts of girls. Imagine walking around with all that nonsense in your head.”

That had been said in defence of Charlie; now it was necessary to say something for Fanwell. It was wrong of Mma Makutsi, she thought, to poke fun at Fanwell's name. “Why is anybody called anything, Mma Makutsi? That boy cannot help it. It is the parents who give children stupid names. It is the fault of the parents.”

“But Fanwell, Mma Ramotswe? What a silly name. Why did they not call him Fanbelt? That would be a good name for an apprentice mechanic, wouldn't it? Hah! Fanbelt. That would be very funny.”

“No, Mma Makutsi,” said Mma Ramotswe. “We must not make fun of people's names. There are some who think that your own name, Grace, is a strange name. I do not think that, of course. But there are probably people like that.”

Mma Makutsi was dismissive. “Then they are very foolish,” she said. “They should know better.”

“And that is what Fanwell himself would probably say about anybody who laughed at his name,” Mma Ramotswe pointed out.

Mma Makutsi had to agree with this, even if reluctantly. She and Mma Ramotswe were fortunate, with their reasonably straightforward names of Grace and Precious, respectively; she had contemporaries who were not so fortunate and had been saddled by their parents with names that were frankly ridiculous. One boy she had known at school had borne a Setswana name which meant Look out, the police have arrived. The poor boy had been the object of derision amongst his classmates and had tried, unsuccessfully, to change the name by which he was known. But names, like false allegations, stick, and he had gone through life with this unfortunate burden, reminded of it every time he had to give details for an official form; looking away so that the person examining the form could be given the opportunity to smile, which they all did.
