“I have been very worried,” he said. “Every night I have been waking up in the quiet hours and have been unable to get back to sleep. I lie in my bed and I turn this way and that and cannot get this one thought out of my head. All the time it is there, going round and round. Just one question, which I ask myself time after time after time.”

“And you never find an answer?” said Mma Makutsi. “The night is a very bad time for questions to which there are no answers.”

Mr Badule looked at her. “You are very right, my sister. There is nothing worse than a nighttime question.”

He stopped, and for a moment or two nobody spoke. Then Mma Ramotswe broke the silence.

“Why don’t you tell us about yourself, Rra? Then a little bit later on, we can get to this question that is troubling you so badly. My assistant will make us a cup of tea first, and then we can drink it together.”

Mr Badule nodded eagerly. He seemed close to tears for some reason, and Mma Ramotswe knew that the ritual of tea, with the mugs hot against the hand, would somehow make the story flow and would ease the mind of this troubled man.

I AM not a big, important man, began Mr Badule. I come from Lobatse originally. My father was an orderly at the High Court there and he served many years. He worked for the British, and they gave him two medals, with the picture of the Queen’s head on them. He wore these every day, even after he retired. When he left the service, one of the judges gave him a hoe to use on his lands. The judge had ordered the hoe to be made in the prison workshop and the prisoners, on the judge’s instructions, had burned an inscription into the wooden handle with a hot nail. It said: First Class Orderly Badule, served Her Majesty and then the Republic of Botswana loyally for fifty years. Well done tried and trusty servant, from Mr Justice Maclean, Puisne Judge, High Court of Botswana.

That judge was a good man, and he was kind to me too. He spoke to one of the fathers at the Catholic School and they gave me a place in standard four. I worked hard at this school, and when I reported one of the other boys for stealing meat from the kitchen, they made me deputy-head boy.
