They could go and have tea in the café on River Walk, the one where you could sit and look out over the car park with the eucalyptus trees in the distance, but they could just as easily have tea in the office and, with minimum craning of the neck, see the edge of that very same stand of eucalyptus trees. Or they could go down to Mokolodi and have tea in the restaurant there; that was perhaps a bit more exciting, but it would require a half-hour trip in the tiny white van to get there, and the tiny white van was not really in a position to make such a trip at present. It was true that it was running, but only just; walking, perhaps, would have been a better word to describe it.

She pushed her plate to the side of her desk. The thought of her van filled her with dread. That morning Mr. J.L.B. Matekoni had left for work first, and when Mma Ramotswe arrived he was standing in front of the garage, chatting to Fanwell, when the tiny white van limped into its parking place at the side of the building. Seeing him, Mma Ramotswe had put her foot down on the accelerator, hoping that the van might just rise to the occasion and drive up at a normal speed. It had not, and the sudden strain on the engine had produced a frightening grinding sound, more serious, it seemed, than any noise the van had previously emitted.

Mr. J.L.B. Matekoni broke off his conversation with his apprentice and walked briskly over to the van.

“What a terrible sound,” he said. “Mma Ramotswe! How long has your van been making that sound?”

Mma Ramotswe swallowed hard. “A sound, Mr. J.L.B. Matekoni? You say that it's making a strange sound? Are you sure it was not some other vehicle?” She looked desperately over her shoulder to see if anything was passing on the Tlokweng Road. The road was quite empty.

“No, it is your van,” he said. “There must be something very wrong with it. I'll take a look at it right away. We've got a couple of hours before the next job is due in.”

Mma Ramotswe realised that she had no escape. “I don't want to be any trouble,” she muttered. “Maybe some other time.”

“Nonsense!” said Mr. J.L.B. Matekoni. “I am your husband, Mma. I cannot have my own wife driving round in a van that makes a noise like that. Think of my reputation-just think of it. What would they say?” He looked at her reproachfully before answering his own question. “They would say that I was not much of a mechanic if that was the sound that my own wife's van made. Everyone would be saying that.”

Mma Ramotswe caught Fanwell's eye. He shrugged, as if to say, I told you, Mma Ramotswe. I told you that there was no hope.

She went into the office, her heart quite cold within her. She knew what would happen, and that a mechanical sentence of doom, uttered in words as powerful and as grave as those of any doctor imparting bad news, would soon be uttered. She decided, though, that there was no point in doing anything but put it out of her mind for the time being. When there is nothing you can do to stop the march of adverse events, then the best thing, she felt, was to get on with life and not to worry. And at that particular moment, Mma Makutsi had come in with the doughnuts, which would be a balm, if only a temporary one, to the anxiety she felt.

And there was plenty to do. When Mma Makutsi arrived in the office that morning, she had found a large envelope tucked under the door, emanating, according to what was written on the outside, from the office of Mr. Leungo Molofololo.

“I've been expecting that,” said Mma Ramotswe, examining the neatly typed sheets of paper that Mma Makutsi handed over to her. “This is the list of the players. This is where we start, Mma.”

Mma Makutsi, standing behind Mma Ramotswe and looking over her shoulder, pointed to one of the names. “Big Man,” she said. “What stupid names these footballers have, Mma. They are just boys. Small boys.”

Mma Ramotswe smiled indulgently. She would not have put it quite like that, but she knew what Mma Makutsi meant. Women did not give one another nicknames. For some reason it was always men, and the names chosen were indeed absurd: private jokes that meant nothing to others; a small humiliation hung around the neck of some unfortunate. Why, she wondered, did men behave like this? You would think that they would learn- and some of them were learning, a bit-but most of them did not. “I know all about Big Man,” she said. “He's the goalkeeper and he is very small. He's not big at all.”

“There you are,” said Mma Makutsi. “That proves it. Why call a small man Big Man? That is very stupid-just as I said.” She peered at the list. “And who is this man called Rops? It says here that he is the captain. Why is he called Rops?”

“Rops is a name I have heard before,” said Mma Ramotswe. “It is a perfectly good name. Unlike this one here. You see that he is called Joel ‘Two Feet’ Koko.”

“Another silly name,” said Mma Makutsi. She moved back to her desk and sat expectantly. “Well now, Mma Ramotswe, what do we do with this list? How do we find the traitor?”

Mma Ramotswe laid the list down. “Let's think, Mma Makutsi. What have we done in the past?”

Mma Makutsi looked puzzled. “We've never had anything to do with a football team, Mma. Not that I recall.”

“I know that,” said Mma Ramotswe. “But we have had to deal with dishonest employees, haven't we? And the simplest way of finding people like that is to see who's richer than he should be. That's always a good way of exposing somebody who's being paid to do something dishonest or who has his fingers in the till.”

Mma Makutsi contemplated this. It was, she agreed, the best first step, but would it necessarily work in this case? What if the traitor acted for some reason other than a financial one? People betrayed others, their country even, for so many different reasons: because they had a score to settle with their employer, because they were in love with somebody who wanted them to commit the act of betrayal, because of jealousy; there were as many sorts of reasons as there were sorts of people.

Mma Ramotswe saw the logic in this. “Yes,” she agreed. “It is always possible that there is somebody in the team who is feeling angry with Mr. Molofololo. Perhaps there is somebody who thinks he should be captain instead of Rops. If you were that person, and you thought that you should be playing up in the front, where all the opportunities to score goals will be had, then you might think, I'll show him. You might think that, might you not, Mma Makutsi?”

Mma Makutsi confirmed that she might. So Mma Ramotswe continued, “And what if you were a footballer who had a girlfriend and this girlfriend was stolen away by the owner of the team or even the captain? What then? You might also say, I'll show them.”

Mma Makutsi listened to this intently. The stealing of a girlfriend was not all that different from the stealing of a fiancé. And that made her mouth go dry with fear. What if Violet succeeded in stealing Phuti, as she so clearly planned to do? What future would there be then for her, for Grace Makutsi? She would never find another man, she feared, or at least she would never find one half as nice as Phuti, let alone one who had his own shop and a great number of cattle. She would continue to be an assistant detective all her days, a woman who had to watch her pennies and see other women, married women, leading more comfortable lives because they had men to go out and earn a living for them. Oh, the injustice of it; oh, the hateful, hateful thought.

She became aware that Mma Ramotswe had said something. “What was that, Mma? I was thinking of something else.”

“I pointed out that we already have a bit of help here from Mr. Molofololo,” said Mma Ramotswe. “You may have noticed that there is a tick against three names on the list. That is something that I asked him to do. And do you know what that means, Mma? Can you guess?”
