“Because I’m traditionally built?” prompted Mma Ramotswe.

Mr Polopetsi raised his hands in a defensive gesture. “I did not say that, Mma,” he protested. “I did not.”

Mma Ramotswe smiled at him reassuringly. “I know you didn’t, Rra,” she said. “Don’t worry. I don’t mind. I’ve been thinking, you know, and I’ve decided that I might go on a diet.”

They had now arrived at the Mokolodi gate, where stone-built rondavels guarded the entrance to the camp. This gave Mr Polopetsi the respite he needed: there need be no further talk of lions or diets now that they had people to talk to. But he would not put to the back of his mind the extraordinary news which Mma Ramotswe had so casually imparted to him and which he would breathlessly pass on to Mma Makutsi the moment he saw her. It was news of the very greatest import: if Mma Ramotswe, stern and articulate defender of the rights of the fuller-figured as she was, could contemplate going on a diet, then what would happen to the ranks of the traditionally built? They would be thinned, he decided.

MMA RAMOTSWE HAD TOLD Mr Polopetsi that there was something brewing at Mokolodi. She could not be more specific than that, as that was all she knew, and she wondered whether, as a man, he would understand. It seemed to her that men were often unaware of an atmosphere and could assume that all was well when it very clearly was not. This was not the case with all men; there were some who were extremely intuitive in their approach, but many men, alas, were not. Men were interested in hard facts, and sometimes hard facts were simply not available and one had to make do with feelings.

Mr Polopetsi looked puzzled. “So what do you want me to do?” he asked. “Why are we here?”

Mma Ramotswe was patient. “Private detection is all about soaking things up,” she said. “You speak to people. You walk around with your eyes wide open. You get a feel for what’s happening. And then you draw your conclusions.”

“But I don’t know what I’m meant to be reaching conclusions about,” protested Mr Polopetsi.

“Just see what you feel,” said Mma Ramotswe. “I’m going to talk to a relative of mine. You just … just walk about the place as if you’re a visitor. Have a cup of tea. Look at the animals. See if you feel anything.”

Mr Polopetsi still looked doubtful, but he was beginning to be intrigued by the assignment. It was rather like being a spy, he thought, and that was something of a challenge. When he was a boy he had played at being a spy and had positioned himself beneath a neighbour’s window and listened to the conversation within. He had noted down what was said (the conversation had mostly been about a wedding which was going to take place the following week), and he was in the middle of writing when a woman came out of the house and shouted at him. Then she had hit him with a broom, and he had run away and hidden in a small cluster of paw-paw trees. How strange it was, he thought, that here he was now doing what he had done as a boy, although he could not see himself crouching beneath a window. If Mma Ramotswe expected him to do that, then she would have to think again; she could crouch under windows herself, but he would certainly not do that, even for her.
