Malik said quickly, 'I wouldn't have thought so. The Taliban are perfectly capable of recruiting for themselves.'

'I'm talking about something different. There are many British-born Muslims fighting out there.'

Malik laughed. 'Daniel, one hears stories, but this is nonsense, pure myth.'

'I'm afraid not, old friend. I've seen the evidence, heard recordings of radio communications in the heat of battle, working-class accents from many of the great cities in the UK.'

'I don't believe it.'

'I've heard it, Malik. In fact, Ferguson, Dillon and Miller have just had a meeting with the President in Washington to work out what to do about it.'

Malik was stunned. 'All right, supposing it is true, what can anyone do to prevent it? If young British Muslims decide to take a holiday in Pakistan to visit the old folk, then end up in a training camp in Waziristan, who can stop them? It's impossible.'

'Well, Ferguson and his people are at least going to make an effort, and I've offered to help.'

Malik was truly shocked. 'But why you, Daniel? This is not your business. You could be asking for big trouble.'

'I have a grasp of the Muslim world that few Christians do. I speak Arabic and, as a young volunteer in the IRA, I was trained in terrorism at Shabwa. I wonder if Shabwa is still in business. And Omar Hamza, the camp commander? What a bastard he was.'

'He would be seventy or more if he is still alive. Shabwa closed down some years ago, though. The IRA no longer used it and, as things changed for the German groups and ETA and the like, there was little need for the facility,' Malik said. 'The thought of young British Muslims using it, though… Why on earth would they want to come to Algeria for their training?'

'You could have said that about the young Irishmen too,' Holley told him. 'Anyway, I'm out of here, off to London.'

'Are you going to see Ferguson?'

'Yes, I want to hear what he intends to do. I feel very strongly about this matter. If there is anything I can do, I will.'

Malik gave in. 'So be it. The blessing of Allah go with you. Do take care, Daniel.'

'Don't I always?'

It was very quiet sitting there in the darkness, the long white curtains ballooning like sails at the window, and Malik went out to find a full moon and the terrace flooded with light. The vista in the night of the harbour below was astonishingly beautiful. He loved this city, always had, just as he loved Daniel Holley, but trouble and Daniel seemed to belong together naturally, and Malik was filled with a grim foreboding.

'What now?' he asked softly, leaning on the balustrade. 'What next?'

The Gulfstream landed at Farley Field late that night. Ferguson's Daimler was waiting, as well as the Mercedes provided by the Cabinet Office for Miller.

'We'll get together later,' Ferguson said. 'I've got to get cracking and prepare that report for the Prime Minister.'

His Daimler moved away and Miller said, 'We'll take you to Holland Park, Sean.' His driver, Arthur Fox, was behind the wheel.

'Care to join me for a late dinner there?'

'No, I need to get to Dover Street and sort this sack of mail that Arthur has brought me. Ferguson's not the only one with problems. I've got the Cabinet Office on my back.' Mentioning his sister, he added, 'I had a text from Monica while you were asleep. She's enjoying being Visiting Professor at Harvard so much, she's agreed to an extension.'

'She didn't tell me.'

'Maybe she's going off you, you mad Irish bogtrotter.'

'And pigs might fly,' Dillon told him. 'Tell her congratulations and I'll be in touch. Now we've got an hour before we get to London, so start on your mail and let me sleep.'

Two hours later, the Malik Shipping plane landed at London City Airport and taxied to the private facility-Daniel Holley had decided to leave Paris earlier than he had planned. His diplomatic passport sped him through and, forty-five minutes later, he was at the Dorchester, where he found Concetto Marietta, the guest liaison manager, waiting to escort him to one of the Park Suites.

He slept for a few hours and then he called Roper. 'When can we meet? I'd love to see what your famous Holland Park safe house looks like from the inside.'

'Ferguson's seeing the Prime Minister this morning, and Miller probably feels he should show his face in the House, but I'm here. So's Dillon, who's upstairs asleep. Come along whenever you want; we'll have lunch.'

'I might just do that. I want to stop off and see a friend first, but then I'll come over.'

'I'll see you when I see you.'

Holley walked up to Shepherd Market, past the restaurants and the shops, then paused at a door with the name 'Selim Malik' painted in gold above it, admired the Egyptian hand-painted temple effigies displayed on either side of the frame, then pressed a button.

The door opened and Selim was there, exactly the same as the last time Daniel had seen him: small and happy, with dark curling hair turning silver, olive face, fringe beard and good humour in his eyes. He wore a ruffled shirt, velvet jacket and trousers, as always.

He was crying as he embraced Daniel. 'It's so good to see you. My cousin Hamid phoned me to say I might expect you, but still I am overcome. This is a champagne moment!'

Selim Malik produced a bottle of Krug and poured each of them a glass, saying, 'It's so wonderful the way everything has turned out. You've outfoxed them all, even the great Putin. Hamid has told me of how you sorted those Albanian bastards out, and the Al Qaeda plot on Putin.' He gripped Holley's arm. 'He will be your friend for life now.'

'I didn't do it for gain,' Daniel told him. 'I did it because what they were planning was wrong.'

'You are a saint.' Selim got up. 'But you must take great care. People who say bin Laden is dead are stupid. What he is, what he stands for, will never die. This doesn't mean I admire him. I fear him, but what I have said is true.'

'I'm afraid you have a point,' Daniel agreed.

Selim went into the other room and returned with a Gladstone bag. 'I've been keeping this in my strong room. It's exactly what you had last time.'

There was an ankle-holster, a silenced Colt.25 and a couple of boxes of hollow-point cartridges, a silenced Walther, ammunition, a razor-sharp flick knife and a bulletproof vest.

'This is wonderful,' Daniel said. 'But hang on to the knife and the vest. I brought my own.'

'You must be prepared for any eventuality,' Selim said. 'If word of your involvement ever got out, Al Qaeda would put you on its international hit list. The blessings of Allah would be on any man who disposed of you.'

'Well, let's hope they don't hear. I've something else to ask you. What do you know about British-born Muslims fighting for the Taliban in Afghanistan?'

Selim frowned. 'Where have you heard this? Some newspaper story, I suppose.'

'Not at all. Selim, you're my friend. Last time we met, we had to face bad men and great danger and you were brilliant, so believe me when I say I know for a fact that many young British Muslims are fighting in Afghanistan. The evidence has been presented to me. Let me tell you about it.'

When Holley was done, Selim was distressed. 'What can I say? I must believe what you tell me is true. But a mystery man known only as Shamrock leading Taliban recruits in a successful battle with Allied troops? It still sounds incredible.'
