People were standing up and had begun to sing. She had been thinking, allowing her mind to wander, and had not noticed that the choir had started to come in. She stood up and watched them as they walked past: Mma Mopoti in good voice, as usual, the head chorister and pillar of the Mothers’ Union. Mma Ramotswe would have to phone her and reply to the invitation to address the Mothers’ Union meeting next month on “The Life of a Private Detective in Botswana.” The title had been suggested by Mma Mopoti, who was widely known for her ability to recite family genealogy, navigating the intricate byways of cousinage that linked just about everyone with everyone else. Mma Ramotswe would accept the invitation; she had to, as Mma Mopoti had pointed out to her that they were distant cousins “way, way back,” and one could not say no to a distant cousin, no matter how far back the link was.

The members of the choir took their seats and the service began. Mma Ramotswe made an effort to follow the proceedings, but there seemed to be so much to distract her, and she abandoned her attempt. This was evidently to be a morning for thinking; no harm in that, and she was not the only one, she suspected, looking about her. And Mma Mopoti herself, sitting there with the choir, had closed her eyes and seemed to be nodding off. She looked off to her right; there was that kind Indian family from Kerala, who had invited her to their daughter’s wedding, along with seven hundred other guests; they loved their weddings, those people-almost as much as the Batswana loved theirs.

Her gaze moved on, and she spotted Mma Mateleke and her husband sitting just a few rows away. She thought it was strange that she had not noticed them before, as she usually exchanged greetings with her friend when she came in. Mma Mateleke was looking down at her hands, rubbing at something-a patch of irritable skin, Mma Ramotswe thought. And of course she could work out where that came from: nurses and midwives had to put that strong antiseptic on their hands-it could hardly do their skin any good. She had met a nurse who had had to find another job for that reason-scrubbing up for the operating theatre had made her hands bleed. She had ended up working in a bank, and had done well, handling money, which did not hurt the skin, but was every bit as dangerous as anything else one might handle.

Mma Mateleke stopped rubbing at her hand and glanced at her husband. Mma Ramotswe watched. Rather to her surprise, she saw that it was not an affectionate look. So Mma Mateleke was cross with Herbert Mateleke-that was interesting. But why? Wives could be cross with their husbands for so many reasons, ranging from the big sins of husbands (drinking too much, becoming violent, looking at other women) to the small sins that men committed so casually (not helping in the house, leaving clothes on the floor, forgetting birthdays and anniversaries, talking about football all the time). Herbert Mateleke was a mild man, rather mousy in his manner; it was difficult to picture him committing any of the big sins. And yet, and yet… Mma Ramotswe had been in practice as a private detective long enough to know that it was often the mild and inoffensive men who behaved most outrageously. Herbert Mateleke might look mild, but he might be having an affair with some blowsy woman somewhere, somebody like Violet Sephotho. Now that was a thought: Herbert Mateleke and Violet Sephotho! No, it was impossible, and she should not even think such thoughts, especially in the cathedral, and especially when the visiting priest was about to speak.

She would try to listen; she really would.

“My brothers and my sisters,” the visitor began, “we are seated here with those we know and those we do not know. But even those we do not know are not strangers. We are united with them in a community which is brought together by one thing, and that one thing is love. It is that love that we profess before one another here today, and it is that love which joins many millions of people throughout the world, wherever gatherings such as that which we attend today take place. That is a sea of love. It touches on the shores of all. There is no place where you cannot see it, even if for some, for the poor and the oppressed, it seems far away, in the distance.

“There are people who say that what we are doing here has no meaning. That it is superstition, that it is wishful thinking. Wishful thinking? It is not that; it is not. Is it wishful thinking to say to yourself and to others that we must love one another? Is it wishful thinking to say that we must forgive others, so that love might grow within our hearts? Is it wishful thinking to imagine that it is only through an effort to love others that a hard and unhappy world may be transformed into a world of kindness and compassion? I do not think that it is.

“There are many creeds and beliefs; there are many ways of leading your life; there are many roads to oneness with the world. But there are other ways, too, and these are all about us. There are those who worship money and success. There are those who do not care about the suffering of others, as long as they are all right. There are those who think that science and mastery of the physical world will bring us happiness and save us at the end of the day. I cannot agree with any of these. I do not think that science alone will deliver us from the consequences of our greed and our stupidity-it is science that has made the very things that are poisoning our world. I do not think that material success will necessarily make us happier-the faces of the rich tell us that; I do not think that a big car or a big house makes a big man. I think that the measure of whether a life has been a good one is how much love there has been in that life-love both given and received.

“This is a place of love, here where we are gathered together today. Our message is love, not fear, nor enmity, nor dismissal of others. It is just love. That is all.”

Mma Ramotswe listened to each of these words, as did all the others present. She glanced along the pew: a man who worked in the diamond office sat quite still, his eyes fixed on the face of this visitor; another man sat with his eyes raised to the ceiling, his brow knitted in concentration and reflection; and a woman in the next row, immediately in front of Mma Ramotswe, a woman whom she recognised but knew little about, other than that she lived by herself near the Sanitas tea garden, this woman, moved by some private sorrow as much as by the words being spoken, cried almost silently, unobserved by others, apart from Mma Ramotswe, who stretched out her hand and laid it on her shoulder. Do not cry, Mma, she began to whisper, but changed her words even as she uttered them, and said quietly, Yes, you can cry, Mma. We should not tell people not to weep-we do it because of our sympathy for them-but we should really tell them that their tears are justified and entirely right.
