Embossed on the matchbox was a tomahawk. The casino's designer had no idea if Mohawk Indians actually fought with hand axes or, indeed, if any Native Americans had ever used such weapons, but tomahawk sounded like Mohawk and 30 West 54th Street was Mohawk land.

Before it became such, the land on which Casino 30/54 sat belonged to Clack Associates, owners of a small hotel much loved by rich European tourists. Augustus Clack III sold the hotel for an undisclosed sum to the billionaire financier, Benjamin Agadir, who promptly swapped it with the Mohawks for seven glass necklaces and a blanket. Since federal regulations specifically allowed casinos to be opened on reservations or any Indian land held in trust, this neatly circumvented the state law that banned the establishment of casinos in New York City.

"Faites vos jeux," announced the croupier, as if inviting a whole table of high rollers to place their bets rather than just the one.

Kashif Pasha ignored the man.

Striking a match, the eldest son and current heir to the Emir of Tunis lifted the match to the tip of his cigar and sucked. His mother disapproved of smoking, gambling, whores and alcohol but since cigars were not expressly mentioned in the Holy Quran, she sometimes kept her peace. Besides, Kashif Pasha was in New York City and she was not.

Quite what Lady Maryam would have made of the striking murals in the gentlemen's lavatory it was best not to imagine. Kashif Pasha's favourite by far featured Pocahontas undergoing what Americans called double entry. For what were undoubtedly good cultural reasons, her lovers both sported tails, the back legs of goats, and small horns.

At home there were no paintings in Lady Maryam's wing of the Bardo and no statues. Even his great-grandfather's famous Neue Sachlichkeit collection of oils had been banished, saved only by the Emir's flat refusal to have them destroyed.

Representative art was abhorrent to his mother for usurping the rights of God. But then this was a woman who found even calligraphy suspect. Which, undoubtedly went some way to explaining why she'd burned the present his father sent her at Kashif's birth. (An Osmanli miniature from the sixteenth century showing the Prophet's wet nurse Hamina breast-feeding.) And this, in turn, maybe helped explain why Emir Moncef had refused to see his wife since.

Kashif Pasha smiled darkly, his favourite expression, and pushed five ivory chips onto the number thirteen.

"Rien ne va plus," announced the croupier, as if he hadn't been waiting. No more bets were to be made. There was a ritual to go through, even though the room was almost empty and the roulette table reserved for Kashif Pasha. The wheel spun one way and the ivory ball was sent tumbling another and when a number other than thirteen came up, Kashif Pasha just shrugged, carelessly he hoped.

Over the course of the next hour the rampart of counters in front of him became a single turret, then little more than ruined foundations and finally almost disappeared, leaving Kashif Pasha with only six ivory chips.

The casino would keep the table open for him while Kashif Pasha ordered more counters, that much was given. High rollers like His Excellency got what they wanted. Their own suites, complimentary meals, limousines to and from the airport. Even use of the casino's own plane if necessary. And what he wanted now was a break.

"Okay," said Kashif Pasha. "I'll be back here at . . ." He glanced at his Rolex and added two hours to the time it was. "At seven," he said. "Have the table reset. New wheel, new ball, new grid, new stack of counters." Which was what his croupier seemed to call those hundred-thousand-dollar red chips.

Sliding his six remaining counters across the table, His Excellency smiled. "For you," he said and watched the croupier blink. It was a good tip, more so since Kashif Pasha was sometimes known not to tip at all. The croupier would give half to the house, but that still left more than he earned in six months.

"Thank you, Excellency," said the man, moving aside to make room for a crop-haired woman who'd been watching the game from a discreet distance.

"Your Highness." This was a title Kashif Pasha didn't warrant but Georgian van Broglie used it anyway. So far she'd acted as facilitator on every visit Kashif Pasha made to Casino 30/54 and he had yet to complain about the social upgrade. "Shall I have the kitchen organize some supper?"

She took his silence as assent.

"Chicken breast," she suggested, "on focaccia, with honey and mustard sauce. A litre of Evian and maybe some more ginger ale?" She nodded to a line of small and empty bottles of Canada Dry, the plastic screw-top kind.

Kashif Pasha's usual order. A glorified chicken sandwich washed down with three plastic flasks of champagne. Quite why a forty-four-year-old North African playboy would want to drink Veuve Clicquot from an empty Canada Dry bottle Georgian van Broglie didn't know, but then she'd never met Lady Maryam.

"Does Your Highness require anything else?"

She saw the man glance across the room to the deerskinned waitress who'd brought him his cigar. "No possible," she muttered apologetically. "House rules. I'd love to make an exception but . . ."

Kashif Pasha sighed. "Send up something similar," he said crossly. "After you've found me the house doctor." He checked his knuckles, which were looking more lopsided than ever. "And get room service to bring me a bucket of ice."

"Nicolai . . ." Emir Moncef's call was for his bodyguard. A small and intense Uzbek whose name was probably something completely different. The Uzbek and a Tajik called Alex took turns to protect the Emir. They were a recent birthday present from the Soviet ambassador. One Moncef had not known how to refuse.

He called again, just in case either guard was within hearing, then turned his attention back to the snake. Death was always going to come. That it chose to manifest as a slithering viper was unexpected but not impossible. Although, if the elderly Emir had been forced to bet (a vice he deplored), he'd have selected a fat-tailed scorpion as being more likely.

Scorpions got carried into camp on the flatbeds of trucks or in date baskets. Once, if he remembered correctly, a fat-tail had hitched a lift in the cuffs of an NCO's dress trousers. The man had succumbed within hours and the Emir had banned cuffs on all uniforms from then on.

He would die as he had lived his last forty years, in the simplicity of Ifriqiya's southern desert. A place where privation reduced leaves to water-protecting spikes and insects hid within thickly waxed bodies to conserve what little water they contained; where beetles survived on one meal in two years, if the habitat so demanded, and glass wort displayed a near-suicidal tolerance for salt.

Tossing back his a'aban, a heavy cloak still worn by Berber men of a certain age, Emir Moncef raised a silver-topped stick. Ready to defend himself.

"Get behind me . . ." His order was aimed at a boy in camouflage who still gripped a Nintendo game pad with frozen fingers.

The Emir's younger son shook his head.

"Murad."

That the Emir used his real name scared the boy almost as much as the viper now crawling its way across a carpet. Mostly his father called him SP, which stood for small pasha, a name he'd been given by his mother before she was killed. His mother had been one of the Emir's guard, an American convert from Los Angeles.

Her Jeep had gone off the side of a cliff. An accident.

"Do as I say."

Looking from his father to the horned viper, the twelve-year-old again shook his head. Snakes were rare in the camp, dangerous or otherwise, because intricate webs of woven copper wire lay buried beneath the perimeter. The webs created an electric field that upset snakes, scorpions and spiders. That was what Eugenie de la Croix said anyway. And it was her job to know these things.
