Mr J.L.B. Matekoni took Mma Ramotswe's hand, touching, for a moment, the glittering ring. He looked at her, and saw that there were tears in her eyes.

"I'm sorry," she said. "I should not be crying, but I cannot help it." 

"Why are you sad?" he asked. "You must not be sad."

She wiped away a tear and then shook her head.

"I'm not sad," she said. "It's just that nobody has ever given me anything like this ring before. When I married Note he gave me nothing. I had hoped that there would be a ring, but there was not. Now I have a ring."

"I will try to make up for Note," said Mr J.L.B. Matekoni. "I will try to be a good husband for you."

Mma Ramotswe nodded. "You will be," she said. "And I shall try to be a good wife for you."

They sat for a moment, saying nothing, each with the thoughts that the moment demanded. Then Mr J.L.B. Matekoni got out, walked round the front of the car, and opened her door for her. They would go inside for bush tea and she would show Rose the ring and the diamond that had made her so happy and so sad at the same time.

CHAPTER SIX

A DRY PLACE

SITTING IN her office at the No. 1 Ladies' Detective Agency, Mma Ramotswe reflected on how easy it was to find oneself committed to a course of action simply because one lacked the courage to say no. She did not really want to take on the search for a solution to what happened to Mrs Curtin's son; Clovis Andersen, the author of her professional bible, The Principles of Private Detection, would have described the enquiry as stale. "A stale enquiry," he wrote, "is unrewarding to all concerned. The client is given false hopes because a detective is working on the case, and the agent himself feels committed to coming up with something because of the client's expectations.
