"We've been hiding," Raf said.

"Who from?" Shibli looked interested.

Raf shrugged. "Ask her," he suggested, but his voice was gentle and his hand on Isabeau's arm was light as he guided her towards a space at one end of a bench.

"Take a seat," Shibli told Raf. "I'll ask when the time comes." And with that, he reached into his kaftan and extracted a book-sized block of hashish, stamped on both sides with Arabic lettering. Pulling a clasp knife from his pocket, the Sufi prised it open and shaved a dark sliver from one corner.

"A fresh sheesha," Shibli demanded and Idries disappeared through the bead curtain, returning with a waterpipe into which the Sufi crumbled both honey tobacco and fragments from the block. He took the first puff himself and passed the waterpipe to Isabeau.

"I'm sorry about Pascal," he said gently and Isabeau nodded. "Such things happen," he added. "Sometimes they're unavoidable." Shibli sighed. "If you know who might have wanted him dead, then you must tell me . . ."

"I don't." Isabeau's voice was small. Already distant.

"Then who were you running from?" The question was Hassan's, from the far corner of the room.

Isabeau glanced from Shibli to Raf, then back at Hassan. "From myself," she said and both Raf and Shibli nodded.

The story was complicated the way such stories usually are. But it seemed Isabeau's brother had been found murdered in an alley behind Maison Hafsid, a restaurant at which some of Café Antonio's staff regularly worked and where her brother was pastry chef.

Ahmed, a cousin to Idries, had been arrested for the crime. Shock mixed with outrage in Idries' voice as he admitted this, but his predominant tone was worry. Despite their apparent closeness Idries admitted his cousin was not eminently likable. Ahmed's habit of using his fists was mentioned. His inability to walk away from a brawl. His use of alcohol.

"But Pascal was stabbed?" Raf asked.

"Yes," said Idries, "that was what it said on the news."

"Did Ahmed carry a knife?"

Raf's question earned him an amused glance from Shibli.

"We all carry knives," Idries said gently.

"But Ahmed was the kind of man to use his fists?"

"That's true," Shibli admitted, eyes suddenly shrewd.

"So, what about witnesses?" Raf asked gently. It was a dangerous game he was playing. Giving them more of himself than was safe to give. But one that was worth the risk. Maison Hafsid was a step closer than Café Antonio. And Shibli had Isabeau under his wing. A wing Raf imagined to be vast and black, batlike, spreading its spines across the city and hiding wonders in its shadow.

"Did anyone see what happened?"

"God . . ." Hassan's voice was harsh. "You talk like a policeman."

"That's because I was a policeman," said Raf flatly. "I've been many things. Not all of them good." He stared round the windowless room and when his gaze stopped it was on Idries. "So, were there any witnesses?"

"We don't know," admitted Idries. His voice tired. "And we can't ask Ahmed," he added, "because the police won't let anyone see him until he's pleaded guilty."

Raf nodded, as if this was to be expected. "Okay," he said, "you'll need to show me the site."

"You be good," Hani told Ifritah, placing the cat firmly on her bed. No sooner done than Ifritah jumped for the suitcase Hani was trying to buckle, claws ripping into old leather as she scrabbled for a hold.

Hani sucked her teeth. "Try," she told Ifritah. "At the very least, try . . ."

Hong Kong Suisse had delivered her cash. Late, admittedly, but Hani was no longer cross about that. She had a party dress made from red silk, green velvet and real gold embroidery. It was designed for someone several years older than Hani and on Zara would have been indecently short. On Hani it fell to her ankles like a ball gown. Added to which Madame Fitmah had even given her a discount on a pair of matching shoes.

Mortgaging her uncle's madersa to finance the trip had been wrong, Hani realized that. And if she'd been allowed access to her own money it wouldn't have been necessary. But to get that would involve asking Hamzah or the Khedive, and they'd want to know why she needed money. Hani shook her head. Sometimes simplicity was everything.

So she'd written to Uncle Ashraf's bank instead, using headed paper and quoting his account number, which had been ridiculously easy to find since it featured on various statements kept in a desk outside his bedroom. Marked confidential, her letter inquired delicately about the opportunities for mortgaging a famous seventeenth-century madersa in a prime position. An equally circumspect (Hani liked that word) reply from HKS suggested that, unless His Excellency really wanted a mortgage of the kind that needed repaying over a number of years, the best option might be a straight loan, at no interest, since usury was obviously forbidden. A settlement fee to be paid as the final part of the reckoning, please see sample contract enclosed.

The bank had used longer words than that–because banks always use complicated words–but that was what Hong Kong Suisse meant.

Hani's reply ended with a flamboyant impression of her uncle's initials and the only thing that stopped her from scanning an original into her laptop and using that was a slight worry that HKS might use some kind of fluorescing system to distinguish fountain pen from printer ink.

As a final touch, Hani found her uncle's spare comb, removed a single hair and dropped it into the envelope, which might be one touch too many but by then she'd stuck the envelope and used her only stamp.

Next morning and the morning after found Hani waiting for the postman, cat in hand. Swapping Ifritah for his fat bundle of letters she chatted about the weather while sorting through the pile. The letter she wanted was one of five. Four of these were bills, three of them red reminders . . .

The loan was agreed and the fact Ashraf Bey had initialled rather than signed his contract as requested was nowhere mentioned: but then Hani remembered reading that the Empire State Building had once been mortgaged against an unsigned deed and she was no longer surprised. All that remained, those were the words HKS used, all that remained was for His Excellency to nominate a receiving account.

Hani took this to mean she should tell the bank where to send the money. So she wrote again on a sheet of the paper taken three days earlier from her uncle's office at the Third Circle.

Stealing it was easy. All Hani had to do was buy a chocolate sundae at Le Trianon, leave most of it and use the café's internal lift to go straight to C3's reception on the floor above. The story she'd prepared about wanting to collect a toy dog from her uncle's office went unused. Madame Ingrid was giving evidence to a tribunal investigating the crimes of Colonel Abad and with their office manager gone, most of her junior staff had left for lunch early, while the rest just nodded at Hani or ignored her.

Taking a single sheet of headed paper from its holder on Uncle Ashraf's desk, Hani promptly changed her mind and slipped a thick wad of the stuff into her rucksack. One never knew when it might become useful. As an afterthought, she added a rubber stamp that sat on the desk beside the wooden box holding the paper. It was a very ornate rubber stamp with brass claws to hold the block of rubber and an ivory handle, but it was still a rubber stamp.

From the desk of Colonel Pashazade Ashraf al-Mansur, Ashraf Bey. Looking at the faint script left by the stamp on the inside of her wrist Hani raised her eyebrows. She hadn't realized her uncle was a colonel; at least, she didn't remember knowing that, but the fact didn't surprise her. Secret agents and assassins were bound to have military ranks, it was obvious really. Everyone in North Africa had a rank of some kind or other.
