For Jamie CG, Sam B and for my father, who has lived many of the things I only write about.

I owe you all, as ever . . .

"Since the prince needs to play the animal he chooses among the beasts the fox and the lion, because the lion cannot protect itself from snares and the fox cannot protect itself from wolves. Therefore the prince must be a fox to recognize traps and a lion to frighten the wolves."

–Machiavelli

"If a lion could speak, we could not understand him . . ."

–Ludwig Wittgenstein

"Unlike foxes."

–Tiri

"Dig," said the fox.

So Ashraf Bey dug. Fingers bleeding and grit compacted beneath his broken nails. With only their sticky rawness to persuade him that he was still in the world of the living.

"Dig harder."

So he did that too. Handful after handful of coarse salt tumbling into his face, blinding his eyes and filling his mouth, half-open to drag oxygen from dead, fetid air. The voice in his head had promised to help Raf reach the surface but only if he obeyed every order without argument. Foxes were good at digging their way out of traps apparently.

Raf's biggest problem before he got buried alive was that no one had told him how far his authority went as the new Chief of Police for Tunis, so he'd decided to assume it went as far as he wanted; which was how he'd ended up . . .

"Like this, really."

Raf wasn't too worried about talking to an animal that didn't exist. For a start he had a number of hallucinogens infecting his bloodstream, from an acid/ketamine mix to a particularly virulent grade of skunk. And besides, he knew Tiri was just an illusion.

They'd been through this. It was sorted out.

According to Tiri a thousand camels once fell through the crust of Ifriqiya's great salt lake, lashed to each other in a baggage train. With the beasts went their cargo of dates, the master of the caravanserai and those who led the animals. Only one man survived, a slave who was driven into the desert for lying. His untrustworthy testimony had been that nothing existed below the ground over which they'd walked but void. What he'd thought was endlessly real was no more solid than the skin of a drum or the shell of an egg sucked dry by a snake.

"So you see," said the fox, "things are . . ."

". . . Never what they seem." Raf punched one fist through earth to reach air. "So you keep telling me."

Later, when he had dry-vomited fear from his belly, wiped dirt and tears from his face and come to terms with the fact that a surprisingly small hole in the ground near his feet represented victory over death, Ashraf Bey came to a deeper realization.

He stank.

There was no doubt about it. Rancid sweat and the smell of excrement rose like heat from his body. And with it came the stink of the grave. A sour, lingering foulness that varnished his nakedness, clogging the inside of his nostrils and infesting even the shafts of his blond hair.

Maybe it was this smell that drew the ghosts or perhaps the drugs in his blood cleared Raf's eyes to let him glimpse inside the egg. Whatever, when he set out across Chott el Jerid the ghosts went with him. Strangers who looked vaguely familiar. Some man he'd seen in a queue. A Chinese boy, both too vague and strange to coalesce. Lady Jalila he recognized. Elegant in her sand-coloured silk jacket stretched across ample breasts. Eyes made up, lips perfect, neck broken . . . She started to say something, then went, her words and ghost ripped apart in a gust of night wind.

Then the fat man came.

Which was, Raf realized, probably inevitable. Of all the people he'd killed it was Felix Abrinsky who mattered the most.

"You okay, blondie?"

Raf put one step doggedly in front of the other. Shaded his eyes from the sight and tried to pretend he wasn't crying. "What do you think?" he said.

"You know how it goes," said Felix. "These days I don't have much of a brain for thinking." And with that he limped away, dragging the foot that had been shattered half a year before, along with most of his skull, in a bomb blast meant for the man he'd just been walking beside.

"Out of my way." Major Jalal jabbed his elbow into the kidney of one photographer and shouldered another into the gutter, watching as frozen slush filled the man's scruffy shoes. Ten paces at most separated the limo from the door of the casino but five photographers barred the way. Well, three now.

"Chill," his boss said with a broad smile. The major wasn't sure if that was an order or if His Excellency was commenting on New York's weather. So Jalal kept his reply to a nod, which covered both bases.

"Prince . . ."

"Over here . . ."

His Excellency Kashif Pasha was used to catcalls and noise from nasrani paparazzi, who whistled at him like he was someone's dog. It was the only thing he hated about coming to New York.

"Look this way."

Kashif Pasha made the mistake of doing just that and found himself staring into the smirking face of Charlie Vanhie, a WASP reporter he'd had the misfortune to meet at least three times before.

"Tell us about your plan to throw a dinner to celebrate your parents' fiftieth wedding anniversary . . ."

Having made the mistake of looking at Charlie Vanhie, the pasha then compounded his error by actually speaking to the man. "Forty-fifth," he corrected, "it will be their forty-fifth."

"What makes you think the Emir will turn up?"

Kashif Pasha stared at the man.

"Given that he won't even be in the same room as your mother. What was it he called her . . . ?"

Major Jalal began to move towards the speaker but His Excellency held up one hand. "Leave it," he told the major. "Let me handle this."

Around the time Kashif Pasha stood on a snow-covered sidewalk in Manhattan, bathed in the light of a flashgun, a small girl sat at a cheap plastic laptop. She was preparing to answer a long list of EQ questions, most of them multiple choice.

Draped around the girl's neck was a grey kitten worn like a collar. Actually, Ifritah was almost six months old but she still behaved like a kitten so that was how the girl thought of her.

Lady Hana al-Mansur, wrote the girl in a box marked name. Then she deleted it and typed Hani instead. There was also a box for her age but this was more problematic since no one was quite sure. She chose 10, because either she was about to become ten, or she was ten already, in which case she'd be eleven in less than a week.

In the box marked nationality Hani wrote Ottoman and when the software rejected this she wrote it again. So then the computer offered her a long list of alternatives which she rejected, finally compromising on Other.

The room where Hani sat was in a house five thousand five hundred and seven miles from New York. In El Iskandryia. A city on the left-hand edge of the Nile Delta. Right at the top where the delta jutted out into the Mediterranean.

The madersa looked in on itself in that way many North African houses do. It was old and near decrepit in places. With a grand entrance onto Rue Sherrif at the front and an unmarked door that led out to an alley at the rear.
