'Isn't that nice?' Dillon said. 'You have a way with the words, Colonel.'

Sergeant Nadim came along the jetty and stood waiting. Hakim said, 'Excuse me a moment.' He went down the short gangway to speak to him.

Dillon took the last glass from the tray, the orderly went below, and Miller said, 'You were saying how sensible it would be to keep quiet about being able to speak Arabic.'

Holley's face betrayed nothing. 'Tell me the worst.'

Which Dillon hurriedly did. 'It all sounded pretty menacing to me.'

Holley frowned. 'It's not that I disbelieve you. But he's been a friend for years.'

'Let's just stay alert and prepare to cope with whatever comes up,' Miller said.

Hakim returned. 'Excuse my bad manners, but I was just discussing your quarters with Sergeant Nadim. You'll be staying on the second boat, Evening Star. He'll command the boat with six men. He is very experienced in the ways of the Khufra, so he'll lead our little invasion, and I will follow, half an hour later, in Fortuna. General Ferguson expressed a wish for you to take part in the action, so I thought my plan would please you.'

'It certainly does,' Miller said.

'So, you will leave at dawn. Four in the morning, gentlemen. But for now, the Cafe Bleu awaits.'

As they went over the side to the jetty, Dillon murmured, 'I thought the French left this country years ago?'

Holley said, 'Just shut up, Sean, you never know. Maybe you'll get a surprise.'

Which they all did. It was a house slightly larger than the others, a terrace open to the sky and looking out to sea. Sergeant Nadim and four men armed with small Uzi machine guns stood guard, menacing and watchful.

There was French wine, Chablis, cold from a deep well where it had been hanging suspended by string. There was a roast lamb to be carved, mounds of rice, peppers of various kinds and onions that had been cooked with the lamb.

Afterwards, drinking more wine, Hakim said, 'I am sorry if the presence of guards has spoiled the meal, but there are those out there in the marshes, possibly even watching us now, who would kill me without compunction.'

'There is no need to apologize. Life is the most precious thing we have,' Dillon said. 'One must be willing to do anything to preserve it. Sometimes, however, even the guards are not enough.'

'Then what is, my friend? If we were sitting here, as we are now, and brigands from the Khufra rushed in to overwhelm us, what would you do?'

Dillon took a pineapple fragmentation grenade from his pocket, pulled the pin and held the release bar tight. 'I would point out that if I released the bar, I might kill myself, but also every person within a fifteen-metre radius.'

The four men with Nadim cried out and backed away hurriedly. Nadim stood firm and Dillon smiled. 'A brave man, your Sergeant, but we'd have died together.' He replaced the pin and put the grenade back in his pocket.

'My friend, you must be insane.' Hakim was horrified.

'Ah, well, I'm from County Down, and they say we're all a bit crazy there.' Dillon turned to his friends. 'I'll need to get a few things from the plane, Harry. If you'll help me, we can leave Daniel to chat on for a while.'

'Of course,' Hakim said, 'but I insist Sergeant Nadim and his men accompany you.'

Dillon said, 'A good man, the Sergeant. I'm sure he'll take care of us perfectly.'

There was a half-moon and a slight breeze as Dillon and Miller walked ahead, Nadim and his men behind.

'There was a purpose to your utterly mad act and now this?' Miller said. 'I'm right, aren't I?'

'Of course you are, but let me listen, Harry.'

They walked in silence, the murmur of conversation behind them, and reached the Falcon. Dillon found the key, opened the airstair door and led the way in. He reached for the weapons bag and opened it. 'I'll get an AK47 for Holley: he's going to need it.'

'Why?' Miller demanded.

'One of the cops asked Nadim why they couldn't cut our throats in bed while we were asleep on the launch. Nadim said it was necessary for us to die in action in the Khufra. He said Hakim had told him it would look better.'

'Anything else?'

'Oh, yes. One of the other guys tried to argue, and Nadim told him he had taken the oath from Colonel Hakim. You know what the oath was, Harry? To put his life on the line to serve Al Qaeda and Osama bin Laden. What do you think of that?'

'I learned a long time ago not to be surprised at anything in our line of work, Sean. It'll be terrible for Holley when we tell him the man who's been his partner's best friend since youth, is what he is. Do you think there's any chance Malik has gone the same way?'

'No, I honestly don't, for all sorts of reasons,' Dillon said. 'The most important thing here is that we've been sold a pup. Clearly, the purpose of our being here isn't to try to get our hands on Shamrock.'

Miller nodded. 'The whole thing has been a ruse to get us here so we could be executed. They were probably hoping that Ferguson and Billy would come along for the ride, too. So there's no Shamrock waiting with Hamza on Diva Island.'

'That's the crazy thing,' Dillon told him. 'It seems Shamrock actually did come in on a plane shortly before we did. He landed at some place called Fasa on the other side of the Khufra. Hamza and his daughter picked him up and he's with them now at Diva. Hamza has been in touch with Hakim, and everyone is very puzzled.'

'And why would that be?' Miller asked.

'It seems he talks like a Brit, but is disguised as a Tuareg, wearing dark blue robes, face veil, the lot!' Dillon smiled wolfishly. 'Wouldn't you say that's a trifle bizarre?'

'I could say a lot more than that,' Miller said. 'What's our next move?'

'To get back to the Evening Star and check in with Holley, who's going to get a bit of a shock. If Hakim is with him, have your AK handy, just in case.' Dillon picked up the weapons bag. 'Let's get moving.'

They left the Falcon, he locked the airstair door again and walked along the beach to the jetty, Nadim and his four men following. Hakim's boat, Fortuna, had five policemen lounging around it, smoking and passing a jug of wine from hand to hand. The second launch, Evening Star, was tied up at a point where the river was swallowed up in a wall of fifteen-foot reeds.

There was a small hut to one side, a large door open to reveal a range of army cots. Two policemen lounged there, smoking in slung hammocks. Nadim and his men joined them and, as Dillon and Miller went on board, Holley and Hakim appeared together, walking along the beach from the Cafe Bleu.

'Ah, there you are,' Hakim called. 'We thought we'd lost you.'

'No chance,' Dillon replied. 'Come and have a nightcap. I've brought a bottle of whisky from the plane, unless it would give you a problem.'

'Not at all, a delightful idea, and over a long life I have discovered that one thing is absolutely for certain. Allah is merciful and understanding of the frailties of men.'

'Excellent,' Dillon said. 'So come on board. Let's go below. The midges are beginning to bite.'

'But of course,' Hakim said amiably.

They went down to the saloon, sat on the benches on either side of the table, and Dillon put four glasses down and poured. He picked one up and toasted them. 'To friendship.'

'To friendship,' Hakim answered.

'Good, I'm glad we've got that over with.' Dillon took out the Walther and put it on the table. 'What would you say that is?'

Hakim laughed. 'A Walther PPK, the new silenced version.'

'Exactly,' Dillon told him. 'And the automatic AK47 which Major Miller is holding across his knees is also silenced, a rare model. He could open a porthole, stick the barrel out and have a very fair chance of knocking off Sergeant Nadim and those six men before they knew what hit them.'
