That experience, called to mind as she made her way into the office, pointed the way. Yes, she would go and speak to Herbert Mateleke and talk to him about somebody else having an affair, and his eyes would give her all the information she needed. After that, she might be in a position to ask him, rather more directly, whether she could help him in any way with any difficulties he was experiencing. But then there would be an additional problem: he might speak to her in confidence, and that would mean that she could not reveal what he said to Mma Mateleke, and she was now, in a way, her client, and … and all that underlined the fact that she should not have said yes in the first place. She sighed; Clovis Andersen was useful, but he usually only came up with general propositions. There was nowhere in the book where you could go and get concrete advice about a situation such as this. Oh, to be able to speak to somebody like Clovis Andersen in person—but he was somewhere far away, and he would never have heard of Mma Ramotswe and the No. 1 Ladies’ Detective Agency, nor of Botswana, perhaps, and he might even be late by now. The back cover of The Principles of Private Detection, so well thumbed in the hands of Mma Ramotswe and Mma Makutsi, said nothing about who the author was, other than to describe him as a “man of vast experience in the field,” and to show a photograph of a man with greying hair and a pair of horn-rimmed spectacles. That was all; there was no mention of an office, or a place, or a family; and the photograph had no background to give any clue as to where he was—which was deliberate, perhaps. The great Clovis Andersen would not want people like her, she thought, pestering him with questions about how to deal with the husband of a friend who might be having an affair, or who might simply be trying to escape a nagging wife, as some husbands were known to do.

Mma Makutsi, now back from compassionate leave, would not have guessed that her employer had been entertaining these doubts. Mma Ramotswe did not believe in burdening others with her worries, and so she greeted her assistant with a cheery smile and a suggestion that she might think of putting on the kettle for late-morning tea. She had just had tea, of course, but that had been a business cup of tea, and that did not count.

Mma Makutsi looked up from her desk, and Mma Ramotswe knew immediately that something was wrong. Phuti, she thought. He was still in hospital. He had taken a turn for the worse. Infection had set in. He had fallen. Perhaps he had got out of bed and forgotten that he had only one foot now, and …

“He is out of hospital,” said Mma Makutsi.
