She looked up at the sky, which was empty, as it usually was. In a few days, though, perhaps even earlier, there would be rain. Heavy clouds would build up and make the sky purple, and then there would be lightning and that brief, wonderful smell would fill the air, the smell of the longed-for rain, a smell that lifted the heart. She dropped her gaze to her garden, to the withered plants that she had worked so hard to see through the dry season and which had lived only because she had given them each a small tinful of water each morning and each evening, around the roots; so little water, and so quickly absorbed, that it seemed unlikely that it would make a difference under that relentless sun. But it had, and the plants had kept in their leaves some green against the brown. When the rains came, of course, then everything would be different, and the brown which covered the land, the trees, the stunted grass, would be replaced by green, by growth, by tendrils stretching out, by leaves unfolding. It would happen so quickly that one might go to bed in a drought and wake up in a landscape of shimmering patches of water and cattle with skin washed sleek by the rain.

Mma Ramotswe leaned back in her chair and closed her eyes. She knew that there were places where the world was always green and lush, where water meant nothing because it was always there, where the cattle were never thin and listless; she knew that. But she did not want to live in such a place because it would not be Botswana, or at least not her part of Botswana. Up north they had that, near Maun, in the Delta, where the river ran the wrong way, back into the heart of the country. She had been there several times, and the clear streams and the wide sweeps of Mopani forest and high grass had filled her with wonder. She had been happy for those people, because they had water all about them, but she had not felt that it was her place, which was in the south, in the dry south.
