He sat on the toilet seat and waited. At nine o'clock he heard footsteps passing down the passage. Then somebody came in and used the cubicle next to his, grunting and farting noisily. At intervals over the next hour men came in, singly or in groups, to use the basins and urinals. However, in the middle of the morning there was a tull. Moses stood up, gathered his parcels, braced himself, let himself out of the cubicle, and briskly crossed to the door into the passage.

The passageway was empty and he started towards the head of the staircase, and then halfway there he chilled with horror and checked in mid-stride.

Two men came up the stairs, and into the passageway, directly towards Moses. Walking side by side, they were in earnest conversation and the shorter and elder of the two was gesticulating and grimacing with the vehemence of his explanation. The younger taller man beside him was listening intently, and his single eye gleamed with suppressed amusement.

Moses forced himself to walk on to meet them, and his expression fixed into that dumb patient mould with which the African conceals all emotion in the presence of his white master. As they approached each other, Moses stepped respectfully aside to let the two of them pass. He did not look directly at Shasa Courtney's face, but let his eyes slide by without making contact.

As they came level, Shasa burst out laughing at what his companion had told him.

'The silly old ass!" he exclaimed, and he glanced sideways at Moses.

His laughter checked and a puzzled frown creased his forehead.

Moses thought he was going to stop, but his companion seized his sleeve.

'Wait for the best bit - she wouldn't give him his pants until he --' he led Shasa on towards his own office, and without looking back or quickening his pace, Moses went on down the staircase and out through the front doors.

The Chev was parked in the lot at the top of the lane where he expected it to be. Moses placed his parcels in the back and then went round to the driver's door. As he slid in behind the steering-wheel, Tara leaned forward from the back seat and whispered: 'Oh thank God, I was so worried about you." The arrival of Harold Macmillan and his entourage in Cape Town engendered real excitement and anticipation, not only in the mother city but throughout the entire country.

The British prime minister was on the final leg of an extensive journey down the length of Africa where he had visited each of the British colonies and members of the Commonwealth on the continent, of which South Africa was the largest and richest and most prosperous.

His arrival meant different things for different sections of the white population. For the English-speaking community it was an affirmation of the close ties and deep commitment that they felt towards the old country. It reinforced the secure sense of being part of the wider body of the Commonwealth, and the certain knowledge that there still existed between their two countries, who had stood solidly beside each other for a century and more through terrible wars and economic crises, a bond of blood and suffering hat could never be eroded. It gave them an opportunity to reaffirm their loyal devotion to the queen.

For the Nationalist Afrikaners it meant something entirely different. They had fought two wars against the British crown, and though many Afrikaners had volunteered to fight beside Britain in two other wars - Delville Wood and El Alamein were only part of their battle honours - many others, including most members of the Nationalist cabinet, had vehemently opposed the declarations of war against Kaiser Wilhelm and Adolf Hitler. The Nationalist cabinet included members who had actively fought against the Union of South Africa's war efforts under Jan Smuts, and many now high in government, men like Manfred De La Rey, had been members of the Ossewa Brandwag. To these men the British prime minister's visit was an acknowledgement of their sovereign rights and their importance as rulers of the most advanced and prosperous nation on the continent of Africa.

During his stay Harold Macmillan was a guest at Groote Schuur the official residence of the South African prime minister, and the climax of his visit was to be an tddress to both houses of the legislature of the Union of South Africa, the Senate and the House of Assembly, sitting together. On the evening of his arrival in Cape Town, the British prime minister was to be the guest of honour at a private dinner party to meet the ministers of Dr Verwoerd's cabinet, the leaders of the opposition United Party and other dignitaries.

Tara hated these official functions with a passion, but Shasa was insistent. 'Part of our bargain, my dear. The invitation is specifically for Mr and Mrs, and you promised not to make an ass of me in public." In the end she even wore her diamonds, something she had not done in years, and Shasa was appreciative and complimentary.

'You really are a corker when you take the trouble to spruce up like that,' he told her, but she was silent and distracted on the drive around the southern slope of Table Mountain to Groote Schuur.

'Something is worrying you,' Shasa said as he steered the Rolls with one hand and lit a cigarette with his gold Ronson lighter.

'No,' she denied quickly. 'Just the prospect of saying the right things to a room full of strangers." The true reason for her concern was a long way from that. Three hours previously, while Moses drove her back from a meeting of the executive of the Women's Institute, he had told her quietly, 'The date and the time has been set." He did not have to elaborate. Since she had picked him up outside the Parliament House just after ten o'clock the previous Monday, Tara he been haunted night and day by her terrible secret knowledge. 'When?" she whispered.

'During the Englishman's speech,' he said simply, and Tara winced.

The logic of it was diabolical.

'Both houses sitting together,' Moses went on. 'All of them, all the slave-masters and the Englishman who is their accomplice and their protector. They will die together. It will be an explosion that will be heard in every corner of our world." Beside her Shasa snapped the cap of the Ronson and snuffed out the flame. 'It won't be all that unpleasant. I've arranged with protocol that you will be Lord Littleton's dinner partner - you get on rather well with him, don't you?" 'I didn't know he was here,' Tara said vaguely. This conversation seemed so petty and pointless in the face of the holocaust which she knew was coming.

'Special adviser on trade and finance to the British government." Shasa slowed the Rolls and lowered his side window as he turned into the main gates of Groote Schuur and joined the line of limousines that were moving slowly down the driveway. He showed his invitation to the captain of the guard and received a respectful salute.

'Good evening, Minister. Please go straight on down to the front entrance." Groote schuur was high Dutch for 'The Great Barn'. It had once been the home of Cecil John Rhodes, empire builder and adventurer, who had used it as his residence while he was prime minister of the old Cape Colony before the act of Union in 1910 had united the separate provinces into the present Union of South Africa. Rhodes had left the huge house, restored after it was destroyed by fire, to the nation. It was a massive and graceless building, reflecting Rhodes' confessed taste for the barbaric, a mixture of different styles of architecture all of which Tara found offensive.

Yet the view from the lower slopes of Table Mountain out ov the Cape Flats was spectacular, a field of lights spreading out to tl dark silhouette of the mountains that rose against the moonbrigl sky. Tonight the bustle and excitement seemed to rejuvenate t ponderous edifice.
