The man managed to get himself invited back to her country, her city, to teach a course of international jurisprudence at a university. They met in afternoons at motels in nearby small towns. His teaching programme was not onerous, he could have been spending hours in the library on private research in Roman Dutch Law as an attribute of colonialism he was known to be doing, on the spot, as it were. Her secretary at Chambers informed callers she was out at a meeting with a client. He encountered the husband and wife at gatherings in her colleagues' houses. It would have looked strange if he had never been invited, as he was on a previous visit, to their house; once again, he came to dinner among other guests. He noticed on a table in this livingroom where the old dog who is at least some company for the quarantined son now lies on a sofa, several tomes and coffee-table books on archaeology. And host Adrian noticed his casual interest, came up to talk to him. A pleasant exchange. Would you like to visit one of the sites? I could arrange for you… Oh Cradle of Man and all that… I should take advantage while I'm here – I must see if I can make some time, yes.

Of course he did not. Ordinary, unavoidable social intercourse is part of the code, one doesn't go beyond it.

But it was inevitable that what was contingent in the Seychelles or Bonn would come too close to be managed without error, a slip of vigilance in the familiar complacency provided by home. They were going to the theatre, the couple, and she had come back from a motel and left an open straw handbag tossed on their bed. Whether Adrian had some disquiet about her afternoon absences from Chambers lately whenever he happened to call her there, and looked in the bag (for an address, a name?) – bizarrely unlikely, either the suspicion or the act – or whether the plastic container that held the rubber diaphragm she wore against conception, familiar to him as part of her feminine paraphernalia in their bathroom cabinet, had fallen out of the bag, is not known. She never will know. Neither will she know how he got himself to open the thing and see it was empty. The device inside her.

So that was a whole new section and paragraph thereof to be added to the code.

He had said nothing when she came into their bedroom brushing her newly-washed red hair he always found so beautiful. They drove to the theatre, he seemed tired and they were comfortably quiet together. They chatted with acquaintances met in the foyer. During the performance she turned to whisper a remark to him and in the dark saw something that set her heart thudding out of rhythm with some sort of premonitory fear. A tear caught the light from the stage on his cheek screwed in anguish.

Anger battled with disbelief in the days, weeks that followed. And pain. Pain has to be managed. He asked, he demanded, who the man was. No-one you know. He guessed, was it -

No-one you know.

This one or that among her lawyer colleagues, their mutual friends -

No-one you know.

He did not accuse her, she did not defend herself; he did not give the ultimatum, end this or end us. He could not end Them, and she could not end Them.

He bore his pain and she bore his pain and anger.

The man went back where he came from. She continued for four years to go to conferences around the world. She was very successful in her profession. How was Adrian to know when there were conferences and when there were not. He was no part of the legal fraternity/sorority cognisant with such opportunities.

These are the facts.

Facts are what constitutes evidence; they do not go further than that.

I have to tell you something. The affair is over.

I thought you were going to tell me you were leaving.

Case closed.

Fifteen years lived since then. In closeness and warmth, unable to do without one another. Never, as the meaningful common phrase goes, looked at another man, and Adrian knew that. As for him – he is the swan who mates for life, he'd had his contingent loves before marriage; they were differently contingent, in the sense of to the real one that was coming. Only once there was an impulse to speak – say, forgive me; a moment of ill-advised weakness occasioned by some passing shakiness in the family, bringing the parents particularly close – one of the girls in trouble, wasn't ever the boy.

Perhaps he would have been amazed to be reminded, confronted, the eyes would have gone black with intensity, resounding the statement, I thought you were going to tell me you were leaving. And there they were living fifteen good years as if what she wanted forgiveness for, never was. Who had made that possible; he: having the inner strength to take the evidence: that his statement was refuted was a sign ordained, not to be questioned: they belonged to each other. Now the age of retirement coming – it's in that historical continuity of their life.

A state of existence. Unimaginable. Because her son, belonging to the historical continuity, brings a state of existence, his, before her days and nights, there returns a chapter not written, included, that surely cannot be believed was possible; could never happen to her as the son could not be thought ever to emanate danger out of the dark of his body.

Forget so much, what a blessing the electronic notebook gadget when listening to long-winded witnesses, and how extraordinary that total recall of four erased years cannot be silenced. How many places on the map were the meeting places, and what ruthless, cunning ingenuity brought those meetings about, the sight and smell and taste as the two strangers' bodies recognized one another beneath muffle of travel clothing in the arrival space of airports caged by the cicada shrill of foreign babble. How many hotel beds fallen to before even any suitcase or briefcase was opened. The bedside telephone where false names were answered to; an independent woman taking on in an hotel register that identity of a nonexistent Mrs-So-and-So. The selective avoidance of restaurants where someone might show recognition, in London or Sydney or the remote hideout on some island. The address of a complicit friend of the man, a law firm to which a c/o letter from home would be sent when – in fact – the recipient received it forwarded to another city, another country. All this so vivid, along with the leisurely shared baths, he liked to exchange the intimacy of each soaping and exploring the other's body, to end as a thrashing fucking. A night – Warsaw, he had the brief of a dispute between Poles and English clients – and there'd been a wonderful, stolen day sightseeing away in Cracow, she heard him use love-names in a call to his wife, and beat her fists in jealousy against pillows, a reversion to angry childhood. How could it have been. A successful lawyer in her forties, even if, as the man told her, using another set of love-names, she had the breasts of a twenty-year-old and the thought of her when he heard her voice on the phone gave him an erection you wouldn't believe, such a hard-on. Don't avoid the way he would regale in being caressed to ready him for a second entry after the first, by the skilful hand on whose finger there was her wedding ring. And was there a night – what pitiless, relentless totality of all this come back – when he was in the hotel bar with a friend of his family who mustn't know she was concealed in the suite upstairs, and lying alone suddenly she was in cold fear, was sure that something was wrong with Adrian, vision of him dimmed by illness, disaster, and she sat up and dialled home. It was not an hour he would be likely to be there. He answered.

– Adrian. – The fearful loss of control in her voice must have brought a certainty: this was a time when she was with the man. Some months had passed since there had been one of her professionally-required absences (Lyndsay has a case in Namibia, your mother's in Toronto for a week).
