Byrne said to me, There's a police checkpoint just around the corner there. I bet that son of a bitch back there has told them to lay for me.' He turned to Billson. 'Yes, walk. Not far – two or three kilometres. Mokhtar will be with you.'

'I think I could do that,' said Billson.

Byrne nodded and went to talk to Mokhtar. I said to Bill-son, 'You're sure you can do it?'

He looked at me wanly. 1 can try.' He turned to look at Byrne. 'Who is that man?'

'Someone who saved your life,' I said. 'Now he's saving your neck.' I went back and got into the cab. Presently Byrne got in and we drove on. I looked back to see Billson and Mokhtar disappear behind some rocks by the roadside.

Byrne was right. They gave us a real going-over at the checkpoint, more than was usual, he told me afterwards -much more. But you don't argue with the man with the gun. They searched the truck and opened every bag and container, not bothering to repack which Byrne and I had to do. They pondered over my passport for a long time before handing it back and then we had to fill in more fiches, again in triplicate.

'This is damn silly,' I said. 'I did this only this morning.'

'Do it,' said Byrne shortly. So I did it.

At last we were allowed to go on and soon after leaving the checkpoint Byrne swerved off the main track on to a minor track which was unsignposted.

The main road goes to In Guezzam,' he said. 'But it would be tricky getting you over the border there. Fort Flatters will be better.' He drove on a little way and then stopped. 'We'll wait for Mokhtar here.'

We got out of the truck and I looked at the map. After a few minutes I said, 'I'm surprised they're not here by now. We were a fair time at the checkpoint and it doesn't take long to walk three kilometres.'

'More like eight,' said Byrne calmly. 'If I'd told him the truth he might have jibbed.'

'Oh!'

Presently Mokhtar emerged on to the side of the road. He was carrying Billson slung over his shoulder like a sack. We put him in the back of the truck and made him as comfortable as possible, revived him with water, and then drove on.

CHAPTER SEVENTEEN

We drove to the Air in easy stages, doing little more than a hundred miles a day. It was during this period that I got to know Paul Billson, assuming that I got to know him at all because he was a hard man to fathom. I think Byrne got to know him a lot better than I did.

In spite of his garrulity at Abalessa, he felt a lot less like talking after passing out while going around the checkpoint, but he was a lot better that evening when we made camp.

We now had tents which were carried on a rack on top of the truck, and while Byrne and Mokhtar were erecting them I dressed Billson's wound. It was clean and already beginning to heal, but I puffed some penicillin powder into it before putting on fresh bandages.

He was bewildered. 'I don't know what's going on,' he said pathetically. 'Who are you?'

'I told you – Max Stafford.'

That means nothing.'

'If I said that I was responsible for security at Franklin Engineering would that mean anything?'

He looked up. 'For God's sake! You mean you've chased all the way out here because I left Franklin's in a hurry?'

'Not entirely – but you get the drift. There's a lot you can tell me.'

He looked around. We were camped on the lee side of a ridge almost at the top. I had queried that when Byrne picked the spot; camping on the flats at the bottom of the ridge would have been better, in my opinion. Byrne had shaken his head. 'Never camp on low ground. More men die of drowning in the Sahara than die of thirst.' When I expressed incredulity he pointed to mountains in the north-east. 'You could have a thunderstorm there and not know it. But a flash flood sweeping through the wadis could come right through here.' I conceded his point.

Billson said, 'Where are we?'

'About fifty miles south-east of Tammanrasset'

'Where are we going?'

'Niger. We're getting you out of Algeria; the police are looking for you. You bent the rules.'

'Why are you doing this for me?'

I put the last knot in the bandage and snipped off the loose ends. 'Damned if I know,' I said. 'You've certainly proved to be a bloody nuisance. Niger is probably the last place in the world I want to go to.'

He shook his head. 'I still don't understand.'

'Have you remembered anything about the man who shot you?'

'A bit,' said Billson. 'I stopped because one of the tyres was going soft and I thought I might have to change a wheel. I was looking at it when this other car came along.'

'Car or truck? 5 A car seemed improbable in Koudia, 'A Range-Rover. I thought he might help me so I waved.

He came up and stopped about ten yards away – then he shot me.'

'Just like that?'

'Just like that. I felt this blow in my shoulder – it knocked me down. It didn't hurt; not then.'
