He felt a prickle of excitement and turned to the open window. They were crossing the shoulder of hills above the town of Windhoek, and the street lights came on even as he watched. The town was the size of one of Cape Town's suburbs and only the few central streets were lit.

The train slowed to a walking pace as they reached the outskirts of the town, and Shasa smelled wood-smoke. Then he noticed that there was some sort of encampment amongst the thorn trees beside the tracks. He leaned out of the window to see more clearly and stared at the clusters of dy shanties, wreathed in the blue smoke of campfires and shaded by the deepening dusk. There was a crudely lettered sign facing the tracks and Shasa read it with difficulty: Vaal Hartz? Hell No! It made no sense and he frowned as he noticed two figures standing near the sign, watching the passing train.

The shorter of the two was a girl, barefoot and with a thin shapeless dress over her frail body. She did not interest him and he transferred his attention to the taller, more robust figure beside her.

Immediately he straightened in shock and rising indignation. Even in the poor light, he recognized that silver-blond shock of hair and the black eyebrows. They stared at each other expressionlessly, the boy in the white dress shirt and black tie in the lighted window and the boy in dusty khaki. Then the train slid past and hid them from each other.

Darling Shasa turned from the window to face his mother. She was wearing sapphires tonight and a blue dress as filmy and light as wood-smoke. You aren't ready yet. We'll be in the station in a minute - and what a mess you have made of your tie. Come here and let me do it for you. As she stood in front of him and shaped the bow with dextrous fingers, Shasa struggled to contain and suppress the anger and sense of inadequacy that a mere glimpse of the other boy had aroused in him.

The driver of the locomotive shunted them off the main track on to a private spur beyond the sheds of the railway workshop and uncoupled them beside the concrete ramp where Abraham Abrahams Ford was already parked, and Abe scampered up on to the balcony the moment the coach came to a stop.

Centaine, you are more beautiful than ever. He kissed her hand and then each of her cheeks. He was a little man, just Centaine's height, with a lively expression and quick, alert eyes. His ears were pricked up as though he were listening to a sound that nobody else could hear.

His studs were diamond and onyx, which was flashy, and his dinner jacket was a little too extravagantly cut, but he was one of Centaine's favourite people. He had stood by her when her total wealth had amounted to something less than ten pounds. He had filed the claims for the H'ani Mine and since then conducted most of her legal business and many of her private affairs as well. He was an old and dear friend but, more important, he did not make mistakes in his work.

He wouldn't have been here if he did.

Dear Abe. She took both his hands and squeezed them.

How is Rachel? Outstanding, he assured her. It was his favourite adiective. She sends her apologies, but the new baby Of course. Centaine nodded, understanding. Abraham knew her preferences for masculine company and seldom brought his wife with him, even when invited to do so.

Centaine turned from her lawyer to the other tall stoop shouldered figure that was hovering at the gate of the balcony.

Dr Twenty-man-jones. She held out her hands.

Mrs Courtney, he murmured like an undertaker.

Centaine put on her most radiant smile. It was her own little game, to see if she could inveigle him into the smallest display of pleasure. She lost again. His apparent gloom deepened until he looked like a bloodhound in mourning.

Their relationship went back almost as far as Centaine's with Abraham. He had been a consulting mining engineer with the De Beers Diamond Company, but he had evaluated and opened the H'ani workings for her back in 1919. It had taken almost five years of her most winning persuasion before he had agreed to come to work for the H'ani Mine as Resident Engineer. He was probably the best diamond man in South Africa, which meant the best in the world.

Centaine led the two of them into the saloon and waved the white-jacketed barman aside.

Abraham, a glass of champagne? She poured the wine with her own hands. And Dr Twentyrnan-Jones, a little Madeira? You never forget, Mrs Courtney, he admitted miserably as she carried the glass to him. Between them it was always full titles and surnames, although their friendship had stood all the tests.

I give you good health, gentlemen. Centaine saluted them, and when they had drunk she glanced across at the far door.

On cue Shasa came through and Centaine watched critically as he shook hands with each of the men. He conducted himself with just the correct amount of deference for their age, showed no discomfort when Abraham over-effusively embraced him and then returned Twentyrnan-Jones's greeting with equal solemnity. She gave a small nod of approval and took her seat behind her desk. it was her sign that the niceties had been observed and they could get on to business.

The two men quickly perched on the elegant but uncomfortable Art Deco chairs and leaned towards her attentively.

It has come at last, Centaine told them. They have cut our quota. They rocked back in their seats and exchanged a brief glance before turning back to Centaine.

We have been expecting it for almost a year, Abraham pointed out.

Which does not make the actuality any more pleasant, Centaine told him tartly.

How much? Twenty-man-Jones asked.

Forty percent, Centaine answered, and he looked as though he might burst into tears while he considered it.

Each of the independent diamond producers was allocated a quota by the Central Selling Organization. The arrangement was informal and probably illegal, but nonetheless rigorously enforced, and none of the independents had ever been foolhardy enough to test the legality of the system or the share of the market they were given.

Forty percent! Abraham burst out. That's iniquitous! An accurate observation, dear Abe, but not particularly useful at this stage. Centaine looked to Twenty-man-Jones.

No change in the categories? he asked. The quotas were broken down by carat weight into the different types of stones, from dark industrial boart to the finest gem quality, and by size from the tiny crystals of ten points and smaller to the big valuable stones.

Same percentages, Centaine agreed, and he slumped in his chair, pulled a notebook from his inside pocket and began a series of quick calculations. Centaine glanced behind her to where Shasa leaned against the panelled bulkhead.

Do you understand what we are talking about? The quota? Yes, I think so, Mater. If you don't understand, then ask, she ordered brusquely and turned back to Twenty-man-Jones.

Could you appeal for a ten percent increase at the top end? he asked, but she shook her head.

I have already done so and they turned me down. De Beers in their infinite compassion point out that the biggest drop in demand has been at the top end, at the gem and jewellery level. He returned to his notebook, and they listened to his pencil scratching on the paper until he looked up.

Can we break even? Centaine asked quietly, and Twenty-man-Jones looked as though he might shoot himself rather than reply.

It will be close,he whispered, and we'll have to fire and cut and hone, but we should be able to pay costs, and perhaps even turn a small profit still, depending upon the floor price that De Beers sets. But the cream will be skimmed off the top, I'm afraid, Mrs Courtney. Centaine felt weak and trembly with relief. She took her hands off the desk and placed them in her lap so the others might not notice. She did not speak for a few moments, and then she cleared her throat to make certain her voice did not quaver.
