The captain leaned back and blew twin streams of blue smoke out through his nostrils. ‘Betrayal, Caitlin,’ he replied. ‘I am talking about betrayal. The man who held you here, Lacan, did not do so on his own recognisance. Nor did he operate as part of a small, traitorous cell. I am afraid that Monsieur Lacan was part of a much larger, and very well organised network of state officials, the Algerian School, as we know them, who had determined that the only possible, rational option for dealing in the long term with the rise of Muslim power in the Middle East, and within France herself, was accommodation.’

‘Appeasement, you mean.’

‘Non, “appeasement” is not a strong enough word, Caitlin. To appease is simply to make morally compromised concessions in order to maintain one’s own tenuous status. That is not what the School’s philosophy now entertains. “Adaptation” is more apt. Although in your language it sounds rather bloodless, it is not. As practised by the Algerian School, it means to slowly adapt the French secular state to the brute realities of its future as an annexe to the dar-al-Islam, as a true Muslim power.’

‘To convert.’

‘Yes. To convert. And to that end they have allied themselves with the intifada, in which your target is a leading player.’

‘Holy shit,’ she said, impressed at last. ‘And the Action Division, how many of them were…?’

Rolland shook his head. ‘Enough. Perhaps one-third. The others were quickly dealt with in the first days of fighting.’

‘But you’ve got a civil war out there. Surely you can’t have whole army divisions who’ve gone over…’

Another headshake from the Frenchman. ‘No. There is fighting between many arms of the military and other organs of the state. But most of those involved see nothing beyond their gun-sights. An army regiment is ordered to put down a mutiny by the Foreign Legion, for example, and the individual soldiers do not understand they are fighting an engagement to suit the ends of the conspiracy. To them, it is just a civil war, and now it is so far advanced that chaos reigns. Accusations, counter-claims, propaganda – all is confusion.’

He leaned forward and stubbed the butt of his cigarette.

‘But this I do know, Caitlin. You can help stop it. Your target, Baumer, he is not the key, but he leads to the key – to the masters of the Algerian School. Take them down, and the intifada is leaderless, nothing more than a rabble. A huge rabble, yes – but not one that can match an army that is not divided against itself.’

‘You want me to kill your own people?’ she asked, still having some difficulty taking it all in.

A new voice spoke up from the doorway behind Rolland, startling her. An American voice. ‘That was always going to be your next mission. That’s why you were targeted.’

‘Wales? Goddamn, Wales!’

As sick in body and soul as she was, Caitlin pushed herself up off the couch and ran over to hug Wales Larrison, almost knocking him off his feet as she threw her arms around his neck.

‘Goddamn, Wales, it’s been… it’s just…’ A small burning lump in her throat grew and grew, until it merged with the ache in her chest and for the first time since she had been captured, Caitlin Monroe let herself go and poured out a torrent of tears.

The rangy, silver-haired Nebraskan enfolded her within a generous bear hug and made no attempt to calm her down, as wretched, pitiful sobs and shudders racked her body.

‘I’m s-s-sorry, Wales. I failed… and…’

He shushed her and stroked her head, patting down masses of thick dark hair still wet from the shower and smelling of cheap shampoo. ‘It’s all right, Cait, it’s all right,’ he said softly. ‘You’ve been sick. I know. They told me. You shouldn’t have been out in the field, let alone trussed up in this shithole… if you’ll excuse my, er, French, Captain Rolland.’

‘But of course, it is a shithole,’ the Frenchman agreed.

Caitlin could feel Larrison’s strong heartbeat through his suit jacket, and that strength flowed through his arms and into her. She slowly regained her composure and pushed herself away.

‘How did you get here?’ she asked shakily, wiping her nose on a shirt cuff. T thought they’d grabbed you, Wales. I thought they’d rolled up the whole network.’

Larrison put one finger on her lip and bade her to be quiet. He then led her back to the couch and eased her down, before sitting himself at the other end.

‘I was in London when everything happened,’ he said. ‘I had to sit on my ass and watch it from there. I’m sorry, Caitlin. I tried to get an overwatch team to you, twice, but the DGSE had a legitimate counter-intel responsibility for shadowing us. We did spy on them, after all. They never penetrated a cell, but their Intelligence Division was aware of us. That’s how they grabbed you the first time you were here. And they blocked both teams I sent in – wiped out the first, grabbed up the other one.’

Caitlin pulled the blanket closer around her shoulders. ‘What’s left of us, Wales? Of Echelon, I mean.’

He puffed out his cheeks. ‘Every op we had running in France was taken down. Every one. With extreme prejudice. The Brits lost their people too. Would have caused a quiet, dirty little war if we hadn’t known about the Algerian School. So now, in France, I’m afraid you’re it. You’re Echelon. Our last designated hitter.’

He indicated the fort around them with a wave of his hand. Somewhere many miles away, more bombs exploded.

‘Lacan had people here, all over,’ Wales went on. ‘This Algerian School, it’s like Captain Rolland told you, they were everywhere. When we sent you after Baumer, they stepped in. He was protected as part of the… accommodation. They were always going to try to keep you off him.’

Rolland put one muddy boot on the coffee table, leaned forward and retrieved his packet of pills. ‘Normally you would have been detained, interrogated, the usual inconveniences,’ he explained. ‘But, the Disappearance, it changed everything. A massive, world-changing shock.’

‘They had contingencies,’ added Larrison. ‘In the event of some foreseeable catastrophe that would cripple the US, or financial collapse, or a nuclear strike – whatever. The Disappearance wasn’t foreseeable, but it was also a hell of a lot more than a simple catastrophe. It wiped us out.’

‘And the contingency?’ said Caitlin.

‘To finish the work of Allah,’ answered Rolland. ‘As soon as it was confirmed what had happened in America, Lacan purged the Action Division and sent his trusted people out to roll up your network. It was not just you, of course. The British also maintained Echelon cadre in France, as Monsieur Larrison explained. They too were targeted. Even your junior partners, the Canadians, Australians and New Zealanders, all of them were smothered.’
