“Who is this man?”

Mma Potsane peered at the photograph, holding it close to her eyes. “I remember that man,” she said. “He worked here too. He is a Motswana. He was very friendly with the American. They used to spend all their time talking, talking, like two old men at a kgotla.”

“Was he from the village?” asked Mma Ramotswe.

Mma Potsane laughed. “No, he wasn’t one of us. He was from Francistown. His father was headmaster there and he was a very clever man. This one too, the son; he was very clever. He knew many things. That was why the American was always talking to him. The German didn’t like him, though. Those two were not friends.”

Mma Ramotswe studied the photograph, and then gently took it off the wall and tucked it into her pocket. Mma Potsane had moved away, and she joined her, peering into the next room. Here, on the floor, there lay the skeleton of a large bird, trapped in the house and unable to get out. The bones lay where the bird must have fallen, picked clean by ants.

“This was the room they used as an office,” said Mma Potsane. “They kept all the receipts and they had a small safe over there, in that corner. People sent them money, you know. There were people in other countries who thought that this place was important. They believed that it could show that dry places like this could be changed. They wanted us to show that people could live together in a place like this and share everything.”

Mma Ramotswe nodded. She was familiar with people who liked to test out all sorts of theories about how people might live. There was something about the country that attracted them, as if in that vast, dry country there was enough air for new ideas to breathe. Such people had been excited when the Brigade movement had been set up. They had thought it a very good idea that young people should be asked to spend time working for others and helping to build their country; but what was so exceptional about that? Did young people not work in rich countries? Perhaps they did not, and that is why these people, who came from such countries, should have found the whole idea so exciting. There was nothing wrong with these people—they were kind people usually, and treated the Batswana with respect. Yet somehow it could be tiring to be given advice. There was always some eager foreign organisation ready to say to Africans: this is what you do, this is how you should do things. The advice may be good, and it might work elsewhere, but Africa needed its own solutions.

This farm was yet another example of one of these schemes that did not work out. You could not grow vegetables in the Kalahari. That was all there was to it. There were many things that could grow in a place like this, but these were things that belonged here. They were not like tomatoes and lettuces. They did not belong in Botswana, or at least not in this part of it.
