Yes, thought Mr. J.L.B. Matekoni, even if no country was absolutely perfect, Botswana, surely, came as close as one could get. He closed his eyes in contentment, and then quickly remembered that he was driving, and opened them again. A car behind him-not a car that he recognised-had driven to within a few feet of the rear of his tow-truck, and was aggressively looking for an opportunity to pass. The problem, though, was that the Lobatse Road was busy with traffic coming the other way, and there was a vehicle in front of Mr. J.L.B. Matekoni that was in no hurry to get anywhere; it was a driver like Mma Potokwane, he imagined, who ambled along and frequently knocked the gear-stick out of gear as she waved her hand to emphasise some point she was making to a passenger. Yet Mma Potokwane, and this slow driver ahead of him, he reminded himself, had a right to take things gently if they wished. Lobatse would not go away, and whether one reached it at eleven in the morning or half past eleven would surely matter very little.

He looked in his rear-view mirror. He could not make out the face of the driver, who was sitting well back in his seat, and he could not therefore engage in eye contact with him. He should calm down, thought Mr. J.L.B. Matekoni, rather than… His line of thought was interrupted by the sudden swerving of the other vehicle as it pulled over sharply to the left. Mr. J.L.B. Matekoni, well versed as he was in the ways of every sort of driver, gripped his steering wheel hard and muttered under his breath. What was being attempted was that most dangerous of manoeuvres-overtaking on the wrong side.

He steered a steady course, carefully applying his brakes so as to allow the other driver ample opportunity to effect his passing as quickly as possible. Not that he deserved the consideration, of course, but Mr. J.L.B. Matekoni knew that when another driver did something dangerous it was best to allow him to finish what he was doing and get out of the way.

In a cloud of dust and gravel chips thrown up off the unpaved verge of the road, the impatient car shot past, before swerving again to get back onto the tarmac. Mr. J.L.B. Matekoni felt the urge to lean on his horn and flash his lights in anger, but he did neither of these things. The other driver knew that what he had done was wrong; there was no need to engage in an abusive exchange which would lead nowhere, and would certainly not change that driver’s ways. “You do not change people by shouting at them,” Mma Ramotswe had once observed. And she was right: sounding one’s horn, shouting-these were much the same things, and achieved equally little.

And then an extraordinary thing happened. The impatient driver, his illegal manoeuvre over, and now clear of the tow-truck, looked in his mirror and gave a scrupulously polite thank-you wave to Mr. J.L.B. Matekoni. And Mr. J.L.B. Matekoni, taken by surprise, responded with an equally polite wave of acknowledgement, as one would reply to any roadside courtesy or show of good driving manners. That was the curious thing about Botswana; even when people were rude-and some degree of human rudeness was inevitable-they were rude in a fairly polite way.

The road was climbing at this point, and the other car soon disappeared over the brow of the hill. Mr. J.L.B. Matekoni wondered why the driver had been in such a rush. He could be late for an appointment, perhaps; or he could be a lawyer due to make an appearance in the High Court down there. That could be awkward, of course, and might just explain a certain amount of speeding. He had heard from a lawyer whose car he fixed that it was a serious matter to be late in court, not only from the lawyer’s point of view, but from that of the client as well, as the judge would hardly be sympathetic to somebody who had kept him waiting. But even if that driver was a lawyer, and even if he was running late, it would not excuse passing on the wrong side, which put the lives of others in danger. Nothing excused that sort of thing.

Mr. J.L.B. Matekoni found himself wondering what Mma Ramotswe would have said about this. When he had first got to know her, he had been surprised at her ability to watch the doings of others and then come up with a completely credible explanation of their motives. Now, however, he took that for granted, and merely nodded in agreement when she explained to him even the most opaque acts of others. Of course that was why this or that was done; of course that was why somebody said what they did, or did not say it, depending on the circumstances. Mma Ramotswe simply understood.

He imagined himself telling her that evening: “I saw a very bad bit of driving on the Lobatse Road this morning. Really bad.”

She would nod. “Nothing new there, Mr. J.L.B. Matekoni.”

“A man shot past me on the wrong side. Whoosh! He was in a very big hurry to get to Lobatse.” He would pause, and then would come the casual query, “Why do you think somebody would risk his neck-and mine too-to get down to Lobatse so quickly?”

Mma Ramotswe would look thoughtful. “A new car?” she asked. “A big one?”

“A very big one,” said Mr. J.L.B. Matekoni. “Three-point-six-litre engine with continuous variable-valve timing…”

“Yes, yes.” Mma Ramotswe did not need these mechanical details. “And the colour of the car?”

“Red. Bright red.”

Mma Ramotswe smiled. “And the driver? Did you see anything of the driver?”

“Not really. Just the back of his head. But he was a very polite bad driver. He thanked me after he had passed me on the wrong side. He actually thanked me.”

Mma Ramotswe nodded. “He must be having an affair, that man. He must be rushing off to see a lady. I suspect he was late, and did not want to keep her waiting.”

“Come on now, Mma! How can you tell that just from the colour of the car?”

“There is that. But there is also the politeness. He is a man who is feeling pleased with the world and grateful for something. So he thanked you.”

He went over this imaginary conversation in his head. He could just hear her, and her explanation, and he thought how she would probably be right, even if he could not see how she could reach a conclusion on the basis of such slender evidence. But that was the difference between Mma Ramotswe, a detective, and him, a mere mechanic. That was a very significant difference, and…

He paused. On the road before him, still some way in the distance, but unmistakable, he could see a car pulled up at the side of the road, a car that he recognised as belonging to Mma Mateleke. And just beyond it, also pulled up at the side of the road, was the large red car that had shot past him a few minutes previously. The driver had got out of the red car and was standing beside Mma Mateleke’s window, looking for all the world as if he had stopped to chat with an old friend encountered along the road. He had been in such a terrible rush, and yet here he was, stopping to talk. What would Mma Ramotswe make of this, Mr. J.L.B. Matekoni wondered, as he began to apply the brakes of his truck.

Mma Mateleke had got out of her car by the time Mr. J.L.B. Matekoni had parked safely on the verge. She greeted him warmly as he approached.

“Well, well, I am a very lucky lady today,” she said. “Here you are, Mr. Matekoni, with that truck of yours. And here is another man, too, who happened to be passing. It is very nice for a lady in distress to have two strong men at her side.”

As she spoke she looked in the direction of the driver of the red car. He smiled, acknowledging the compliment, and then turned to Mr. J.L.B. Matekoni.

“This is Mr. Ntirang,” said Mma Mateleke. “He was travelling down to Lobatse and he saw me by the side of the road.”

Mr. Ntirang nodded gravely, as if to confirm a long and complicated story. “Her car had clearly broken down,” he said to Mr. J.L.B. Matekoni. “And this is miles from anywhere.” He paused before adding, “As you can see.”
