The passenger didn’t seem the least bit surprised by the request. “What about the people I’m travelling with?” he asked. The woman next to him was down on the manifest as his wife and, like the man, was travelling on a Yemeni diplomatic passport. A grey-haired older woman, apparently his mother, was sitting behind him, and on the other side of the cabin were his two young children. All had Yemeni diplomatic passports.

“I’m sorry, sir, they’re also to stay behind.”

The passenger nodded. “I understand,” he said quietly. “Will you tell my children while I explain to my mother?”

The stewardess went over to explain to the youngsters while Ahmed turned around and spoke to the old woman. Elba Maria Sanchez had grown accustomed to waiting in airliners while immigration officials took advice on whether or not her son should be admitted into their country. The family had been turned away from most of the countries in the Middle East, and previous safe havens including East Germany and Hungary had turned their backs on their old cohorts in their rush to embrace capitalism. Even the Sudanese had betrayed them.

The passengers shuffled off the plane. The stewardess asked Ahmed if he wanted a drink while he waited but he declined. He picked up a copy of Newsweek and idly flicked through it. “It’s always the same,” said his wife bitterly. “They should be ashamed of themselves, these people, they have no loyalty. After all we’ve done for them.”

“Be patient, Magdalena,” said the man, his eyes on the magazine.

“Patient! Ha! I was patient in Tripoli, I was patient in Damascus, I’ve been patient in virtually every airport in the Middle East. Face it, Ilich, no-one wants us any more. We’re an embarrassment.”

“Hush,” he said quietly. “You’ll upset the children.”

She looked like she was about to argue but before she could speak a small, unimposing man in a dark suit appeared at the doorway. He carried a shiny black briefcase and he nervously rubbed his moustache as he approached Ahmed. He introduced himself as Khatami, just the one name, and he didn’t tell the passenger who he represented. There was no need. He suggested that they go back into the Business Class cabin where they could have some privacy and Ahmed followed him along the aisle. Ahmed’s children looked anxiously up at him and he winked at them reassuringly. Khatami stood to the side to allow Ahmed past and then he whisked the blue curtain closed. Ahmed sat down in an aisle seat and Khatami took the seat opposite him, balancing the briefcase on his knees. Khatami seemed uneasy and beads of perspiration dripped down either side of his beakish nose. “Your passport, please,” he said, holding out his hand.
