'Certainly has. We've made millions.'

'And weaponry?' Ferguson asked.

'We decided as a matter of policy not to bother. There's lots of old-fashioned communist rubbish available, masses of AK47s, RPGs, Stingers. On the North-West Frontier, weapons like that are flogged in the bazaars like sweeties. It's dirty business. Lots of people do it, even some respectable firms, but we don't. Talbot International is family-owned, the ex-Chairman an old comrade of mine. Colonel Henry Talbot. Old Ulster family, Protestant to the bone. Henry was an MP at Stormont and they made him a Grand Master in the Orange Lodge. I always said he was to the right of Ian Paisley.'

'And now?'

'Retired. The grandson's the Managing Director – he's the one who really runs things. Major Justin Talbot – Grenadier Guards, you'll be pleased to know – got shot up on his last tour in Afghanistan and felt it was time to go. He goes where I can't. I managed to make it to Islamabad last year for discussions with the Pakistan government, but that was it. I'm too old for that kind of thing. It's bloody rough these days. All sorts of illegal arms traffic passing over the Afghan border.'

'Arms for the Taliban?' Ferguson asked.

'Who else?' Sir Hedley frowned. 'Have you got a particular interest in this?'

Miller answered. 'The Prime Minister is concerned about reports that British Muslims are serving with Taliban forces.'

Sir Hedley nodded. 'I've seen the odd newspaper reports to that effect, but I can't believe it's in any great numbers. I know one thing. It would be treason.' He turned to Miller. 'Wouldn't you agree?'

'Yes, I would, but in the brave new world we live in, it'd be a nightmare for the government to prosecute.' He smiled crookedly. 'But we'll have to cross that bridge when we come to it. Would you like another drink, sir?'

'I think I would,' Sir Hedley said, and added, 'Here's Justin, just coming in the door.'

Justin Talbot had left his flight bag with the porter and had put on a tie. He stood there, smiling, a slightly incongruous figure with the tie and the old flying jacket.

'Come in, Justin, and join us. I've just run into an old comrade, Major General Charles Ferguson and his friend, Major Harry Miller.'

Justin Talbot was thunderstruck. Of all the people to meet – the two men he'd been most warned about. The voice in his brain said: Don't panic. Smile. Your background is impeccable. You're Managing Director of a firm worth hundreds of millions of pounds; you're a war hero.

So he produced that easy charm and said to Ferguson, 'Quite an honour, General. You're a legend in the regiment.'

It had the desired effect, for Ferguson was only human, but Miller was not taken with him and wondered why. The deliberate stroking of Ferguson, perhaps, or the wonder-boy appearance. Certainly the air of cynical good humour was used for effect, and most people probably fell for it, especially women.

'You'll have a drink with us?' Sir Hedley asked.

'No can do. I'm back from Lahore and found out my mother has gone over to County Down to see to her father, who's apparently not too well. I'm flying myself over, so no alcohol for me.'

'Indeed, but well-met, anyway. Our friend, Major Miller here, is apparently an Under-Secretary of State, although we're not allowed to know what ministry.'

'Sounds intriguing,' Talbot said.

'We've been having an interesting debate about the suggested presence of British Muslims fighting for the Taliban,' said Sir Hedley.

'I see,' Talbot said.

Ferguson said, 'There's a concern in government circles. Have you any opinion on the matter?'

Which was exactly the question Talbot had been hoping for. 'I certainly have. It's not a "suggested" presence: it's very real. I have excellent connections with the Pakistan Army and they tell me many of the voices on the radio are definitely English.'

'Have you heard them yourself?' Miller asked.

'Yes, on a few occasions when I was up near Peshawar and very close to the Afghan border. Sometimes you can pick up the sounds of battle on the other side.'

'In Afghanistan itself? Can I ask what you were doing there?' Miller went on.

'We sell trucks used for army transportation and driven by civilian personnel. Part of our sales package guarantees maintenance.'

'A big operation,' Ferguson told him.

'Yes, it is. If the government is concerned about anything up there, I suppose they could always send somebody to take a look.'

Sir Hedley broke in. 'We'd be happy to assist in any way. Maybe you and Miller could go and have a look-see, Charles?'

'It's certainly a thought,' Ferguson said. 'Would you be there?' he asked Talbot.

'Not if I can help it. It's the pits, and I've had enough of Afghanistan to last me a long time. But I have excellent staff, and I'd be happy to put them at your disposal. Just let me know.'

'I will indeed. Come on, Harry, we'd better move.' Ferguson got up. 'Take care of yourself, Hedley, old son. Let's not leave it so long. Nice to meet you, Major.' He shook Talbot's hand. 'My regards to your grandfather. I had some dealings with him when I was in Belfast at the height of the Troubles. Frankly, he was a bit of a bastard.'

Talbot held on to his hand for a moment. 'You're wrong, General. He was the bastard.'

Ferguson and Miller went downstairs and called in their limousines. 'What did you think?' asked Ferguson.

'Of Talbot? I can't say I warmed to him.'

'Perfectly understandable, Harry. He's too good-looking, he's heir to a family fortune of eight-hundred million pounds, he's a war hero. Shall I carry on?'

'I'd rather you didn't,' Miller said. 'What now?'

'Time for a council of war. I'll see you at Holland Park.' Ferguson got in his Daimler and was driven away. An hour later, they met in the computer room, Ferguson presiding, with Miller, Holley, Roper, and their occasional colleagues Harry and Billy Salter.

Ferguson said, 'I'm pleased to say that Daniel Holley has agreed to join us and offer his special services to the matter in hand.'

Harry Salter glared at Holley, then said, 'This is completely out of order. This geezer arranged for someone to try and burn down my pub.'

'Which is still standing,' Ferguson told him. 'We're all in one piece, including Lady Monica Starling, whose life he saved. It's like war, Harry – yesterday's enemies are today's allies. All sins are forgiven. Daniel has even passed on to our old friend Colonel Josef Lermov information about a possible Al Qaeda assassination attempt on Vladimir Putin.'

'Christ,' Harry Salter said, 'whose side are you on, Holley? You certainly spread yourself around.' He turned to Ferguson. 'Okay then, what's it all about?'

Roper said, 'I've got quite a show for you. Listen and learn.'

When it was over, Harry Salter said, 'What a bastard, that Shamrock guy. Calls himself British. He should have his balls chopped off.'

'Rather drastic, but you have a point,' Ferguson said. 'Anyone else?'

Billy Salter said, 'The business about these young Muslims turning up in battle with the Taliban. Yes, it's diabolical, but I've got a feeling there probably is no organization as such behind this. They've all got relatives in Pakistan, they were born here, they've got a passport, they can travel there any time they want. So maybe some Mullah at the local mosque who's a Jihadist has given them an address. That's probably the extent of it.'

'I agree with him,' Dillon put in. 'I think the important thing here is for us to find out who Shamrock is.'

'You're right, Sean,' Miller told him. 'But we can't exactly go hunting for him in the depths of Helmand province. He isn't out there leading a life of daily hardship. He's staging a "spectacular", as he calls it, and then getting out of there. Who knows where he is?'
