'Sure, but this is better for you in the desert. You can have coffee when we get back to Tarn. Expensive, though.'
The sun was past its height and sinking towards the west as we sat in the shade of the Toyota. This was the hottest part of the day and, in Koudia, that meant really hot. The bare rocks were hot enough to fry eggs and the landscape danced in a constant heat shimmer.
I remarked on this to Byrne, and he grinned. 'This is winter – would you like to be here in summer?'
'Christ, no!'
This is why they wouldn't give Billson a permis. And come nightfall the temperature will drop like a rock. You leave water exposed out here and you'll have half an inch of ice on it by three in the morning. If Billson is lost he'll either have burned to death or frozen to death.'
'I like a cheerful man,' I said acidly.
Mokhtar had disappeared about his private business but suddenly he appeared on top of a boulder about two hundred yards away. He gave a shrill whistle which attracted our attention, and waved both his arms. 'He's found something,' said Byrne, scrambling to his feet We went over to Mokhtar and that took us more than ten minutes in that ankle-breaking terrain. When we were fifty yards away Mokhtar shouted something, and Byrne said, 'He's found a truck. Let's see if it's a Land-Rover.'
As we scrambled on top of the boulder, which was as big as a moderate-sized stately home, Mokhtar pointed downwards, behind him. We walked over and stared to where his finger was pointing. There was a vehicle down there behind the boulder, and it was a Land-Rover. Or, at least, it had been – it was totally burnt-out. There was no sign of Billson or anyone else, and I suddenly realized that 1 wouldn't know Billson if I saw him. I was a damn fool for not having a photograph.
Byrne said, 'The black smoke would come from the burning tyres. Let's get down there.'
Going down meant going back the way we had come and walking around the boulder. As we came in sight of the Land-Rover, Byrne, in the lead, spread his arms to stop us. He spoke rapidly to Mokhtar who went on ahead, peering at the ground. Presently he waved and Byrne walked over to him, and they had a brief discussion before Byrne beckoned to me.
'There's been another truck here; its tracks are on top of those of the Land-Rover, and it went that way.' He pointed back in the general direction of the Toyota.
'Where's Billson?' My mouth was dry.
Byrne jerked his head at the Land-Rover. 'Probably in there – what's left of him. Let's see.'
He stood up and we walked over to -the Land-Rover. It was a total wreck – a burnt-out carcass; it sat on the ground, the wheel rims entangled in the steel reinforcing wires of what had been tyres. There was still a lingering stench of burning rubber in the air.
The window glass had cracked and some of it had melted, and the windscreen was totally opaque so that it was difficult to see inside. Byrne reached out and tugged at the handle of the door on the driver's side and cursed as it came away in his hand. He walked around and tried the other door. He jerked it open and looked inside, with me looking over his shoulder.
The inside was a mess. The upholstery had burned, releasing blackened coil springs, and even the plastic coating of the driving wheel had burnt away, leaving bare metal. But there was no body, either in front or on the rear seats.
We went around to the back and got the tailgate open, to find scant remnants of what appeared to be two suitcases. Again, no body. I said, 'The other truck must have taken him away.'
'Maybe,' said Byrne noncommittally. He poked around a bit more in the ruined Land-Rover, then he straightened up. 'Did Paul Billson have any enemies?'
'He may have had.' I went cold as I realized we were speaking of Billson in the past tense just as his half-sister had done. I said, 'I hardly think he'd have the kind of enemy who would follow him to the middle of the Sahara to kill him.'
'Mmm.' Byrne made a nondescript noise and continued his examination. 'I've seen lots of burnt-out trucks,' he said. He picked up a jerrican lying to one side, snapped open the cap, and sniffed. 'He had gas in her e. He must have been carrying it in the back there, because he had no cans strapped on the side when he left. This is empty now.'
'Perhaps there was an accident when he was refilling the main tank.'
Then where's the body?'
'As I say – the other truck rescued him.'
Byrne stood back and looked at the Land-Rover, then talked more to himself than to me. 'Let's see; twenty-eight gallons in the main tank plus about four in the can – that's thirty-two. He'd need at least twenty to get here, so he was in trouble without a fire – he didn't have enough gas to get back to Tarn. That leaves twelve gallons – eight in the tank and four in this can, I'd say.'
'How do you know the can wasn't empty? He could have refilled his main tank anywhere – even before Assekrem.'
