She began to wonder whether this was the right job for her after all. It was all very well thinking that one might help people to sort out their difficulties, but then these difficulties could be heartrending. The Malatsi case had been an odd one. She had expected Mma Malatsi to be distraught when she showed her the evidence that her husband had been eaten by a crocodile, but she had not seemed at all put out. What had she said? But then I have lots to do. What an extraordinary, unfeeling thing for somebody to say when she had just lost her husband. Did she not value him more than that?

Mma Ramotswe paused, her spoon dipped half below the surface of the simmering stew. When people were unmoved in that way, Mma Christie expected the reader to be suspicious. What would Mma Christie have thought if she had seen Mma Malatsi's cool reaction, her virtual indifference? She would have thought: This woman killed her husband! That's why she's unmoved by the news of his death. She knew all along that he was dead!

But what about the crocodile and the baptism, and the other sinners? No, she must be innocent. Perhaps she wanted him dead, and then her prayer was answered by the crocodile. Would that make you a murderer in God's eyes if something then happened? God would know, you see, that you had wanted somebody dead because there are no secrets that you can keep from God. Everybody knew that.

She stopped. It was time to take the pumpkin out of the pot and eat it. In the final analysis, that was what solved these big problems of life. You could think and think and get nowhere, but you still had to eat your pumpkin. That brought you down to earth. That gave you a reason for going on. Pumpkin.

THE BOOKS did not look good. At the end of the first month of its existence, the No. 1 Ladies' Detective Agency was making a convincing loss. There had been three paying clients, and two who came for advice, received it, and declined to pay. Mma Malatsi had paid her bill for two hundred and fifty pula; Happy Bapetsi had paid two hundred pula for the exposure of her false father; and a local trader had paid one hundred pula to find out who was using his telephone to make unauthorised longdistance calls to Francistown. If one added this up it came to five hundred and fifty pula; but then Mma Makutsi's wages were five hundred and eighty pula a month. This meant that there was a loss of thirty pula, without even taking into account other overheads, such as the cost of petrol for the tiny white van and the cost of electricity for the office.

Of course, businesses took some time to get established- Mma Ramotswe understood this-but how long could one go on at a loss? She had a certain amount of money left over from her father's estate, but she could not live on that forever. She should have listened to her father; he had wanted her to buy a butchery, and that would have been so much safer. What was the expression they used? A blue-chip investment, that was it. But where was the excitement in that?

She thought of Mr J.L.B. Matekoni, proprietor of Tlokweng Road Speedy Motors. Now that was a business which would be making a profit. There was no shortage of customers, as everybody knew what a fine mechanic he was. That was the difference between them, she thought; he knew what he was doing, whereas she did not.

Mma Ramotswe had known Mr J.L.B. Matekoni for years. He came from Mochudi, and his uncle had been a close friend of her father. Mr J.L.B. Matekoni was forty-five-ten years older than Mma Ramotswe, but he regarded himself as being a contemporary and often said, when making an observation about the world: "For people of our age…"

He was a comfortable man, and she wondered why he had never married. He was not handsome, but he had an easy, reassuring face. He would have been the sort of husband that any woman would have liked to have about the house. He would fix things and stay in at night and perhaps even help with some of the domestic chores-something that so few men would ever dream of doing.

But he had remained single, and lived alone in a large house near the old airfield. She sometimes saw him sitting on his verandah when she drove past-Mr J.L.B. Matekoni by himself, sitting on a chair, staring out at the trees that grew in his garden. What did a man like that think about? Did he sit there and reflect on how nice it would be to have a wife, with children running around the garden, or did he sit there and think about the garage and the cars he had fixed? It was impossible to tell.

She liked to call on him at the garage and talk to him in his greasy office with its piles of receipts and orders for spare parts. She liked to look at the calendars on the wall, with their simple pictures of the sort that men liked. She liked to drink tea from one of his mugs with the greasy fingerprints on the outside while his two assistants raised cars on jacks and cluttered and banged about underneath.

Mr J.L.B. Matekoni enjoyed these sessions. They would talk about Mochudi, or politics, or just exchange the news of the day. He would tell her who was having trouble with his car, and what was wrong with it, and who had bought petrol that day, and where they said they were going.

But that day they talked about finances, and about the problems of running a paying business.

"Staff costs are the biggest item," said Mr J.L.B. Matekoni. "You see those two young boys out there under that car? You've no idea what they cost me. Their wages, their taxes, the insurance to cover them if that car were to fall on their heads. It all adds up. And at the end of the day there are just one or two pula left for me. Never much more."

"But at least you aren't making a loss," said Mma Ramotswe. "I'm thirty pula down on my first month's trading. And I'm sure it'll get worse."

Mr J.L.B. Matekoni sighed. "Staff costs," he said. "That secretary of yours-the one with those big glasses. That's where the money will be going."

Mma Ramotswe nodded. "I know," she said. "But you need a secretary if you have an office. If I didn't have a secretary, then I'd be stuck there all day. I couldn't come over here and talk to you. I couldn't go shopping."

Mr J.L.B. Matekoni reached for his mug. "Then you need to get better clients," he said. "You need a couple of big cases. You need somebody rich to give you a case."

"Somebody rich?"

"Yes. Somebody like… like Mr Patel, for example."

"Why would he need a private detective?"

"Rich men have their problems," said Mr J.L.B. Matekoni. "You never know."

They lapsed into silence, watching the two young mechanics remove a wheel from the car on which they were working.

"Stupid boys," said Mr J.L.B. Matekoni. "They don't need to do that."

"I've been thinking," said Mma Ramotswe. "I had a letter the other day. It made me very sad, and I wondered whether I should be a detective after all."

She told him of the letter about the missing boy, and she explained how she had felt unable to help the father.

"I couldn't do anything for him," she said. "I'm not a miracle worker. But I felt so sorry for him. He thought that his son had fallen in the bush or been taken by some animal. How could a father bear that?"

Mr J.L.B. Matekoni snorted. "I saw that in the paper," he said. "I read about that search. And I knew it was hopeless from the beginning."

"Why?" asked Mma Ramotswe.

For a moment, Mr J.L.B. Matekoni was silent. Mma Ramotswe looked at him, and past him, through the window to the thorn tree outside. The tiny grey-green leaves, like blades of grass, were folded in upon themselves, against the heat; and beyond them the empty sky, so pale as to be white; and the smell of dust.
