'This is crazy,' he said. 'You must mean Erak. But he was being taken to Mararoc with an Arridi caravan. How has he suddenly turned up with these Tualaghi?'

Jamil shrugged. Umar rubbed his nose thougthfully.

'Perhaps the Tualaghi attacked the caravan and captured the Northman?' he suggested.

Will nodded to himself, thinking furiously. If that had been the case, Gilan and Halt would have been able to read the signs of the attack. Then they would have set out after the ambushers, with Selethen and his men in company. He shook his head to clear his thoughts. It didn't matter how it had happened, he realised. The plain fact was that it had happened.

He was surprised, however, that Halt and Gilan had been so careless as to allow the Tualaghi bandits to get wind of them.

'Do you have any idea how the Tualaghi learned that my friends were tracking them?' he asked.

This time, the Bedullin's eyes slid away in shame. He hesitated a moment before he could bring himself to answer.

'I'm afraid I led them to your friends' camp,' he said. And as Will began to rise angrily from his sitting position, he hastily held out a hand.

'No! Please! It was unintentional! I had no idea your friends were there. I saw the Tualaghi party in the distance and I went closer to find out more about them. They were a much larger party than usual – at least two hundred, maybe more. After dark, I crept close to their camp to see more clearly. That was when I saw the Northman – they had him chained up in the open.

'I left before dawn and headed towards here. I must have passed close to your friends' camp without ever seeing them. But a Tualaghi rearguard scout found my tracks and followed them later that morning – and they led him to your friends. They were travelling parallel to the Veiled Ones, several kilometres away. If I hadn't inadvertently crossed their track, the Tualaghi would never have known they were there.'

'How do you know all this?' Will asked.

The scout replied unhappily. 'I went back the next day to check further. I had no idea then that my tracks had been discovered. But I saw where the Tualaghi had followed me, saw where they crossed your friends' path and turned to follow them. They must have thought I was part of that group. I'm sorry, Will. I had no idea I was bringing danger to your friends.'

Will waved the apology aside. It hadn't been Jamil's fault, he realised. It had just been damnable bad luck – Jamil had been the chance, unexpected element that had led to Halt and the others being captured. As Halt had told him so many times, if anything can go wrong, it will.

'You couldn't have known,' he said. 'Do you have any idea where they might be taking them?' He addressed the question to both Jamil and Umar.

'I'd say they were heading for the massif,' Jamil said. Will looked to Umar, who explained.

'It's a huge range of cliffs and hills and mountains to the north-west. There are Arridi villages scattered throughout the hills and the Tualaghi often ride in and impose themselves on the villagers – stealing their crops and killing their livestock. A party of two hundred would have no trouble taking over a village – or even a small town.

Chances are they have one in mind and they'll use it as their headquarters for a month or two. Then, when the herds and food supplies are exhausted, they'll move on.'

Will reached into his shirt and produced the map Selethen had given him.

'I've got to go after them! Show me on this,' he demanded. But Umar put his hand over the younger man's to calm him.

'Slow down, friend Will,' he said. 'Nothing will be gained by rushing off into the desert without a plan. The Tualaghi are dangerous enemies. I need to talk with my council and then we'll see what can be done.'

Will went to argue but the pressure of Umar's grip increased.

'Trust me on this, Will. Give me an hour,' he said. Reluctantly, Will relaxed, folding the chart and returning it to its hiding place inside his shirt.

'Very well,' he said. 'An hour. But then I'm leaving.'

Will returned to where Tug waited patiently and loosened the saddle girths so the horse would be more comfortable. Then he sat, his back resting against the bole of a palm tree, his eyes closed, while he tried to make sense of the situation.

Somehow, he would have to rescue his friends. He knew that much. But how? He was alone and he was unfamiliar with the territory. Against that, his friends were being held by two hundred armed bandits – cruel and merciless men who would cut their throats without hesitation. He was a foreigner. He would stand out among the Arridi villagers, even if he could manage to find the correct village in the first place. He realised that he didn't even know where to pick up the trail left by the Tualaghi. And if his recent attempts at navigation were anything to judge by, he'd probably never find them.

He must have dozed, affected by the heat of the day. He was woken by the sound of Umar lowering himself to the sand beside him with a faint grunt of exertion.

'We've talked,' he said simply. Will looked at him. There was no hint of what he and his advisers had decided in his bland expression.

'Will you let Hassan guide me to where the Tualaghi captured my friends?' he said.

Umar held up a hand, palm outwards, to stop him. 'Let me explain. Here are the facts I put to my council. The Tualaghi are no friends of ours. A large war party like this means they're up to no good and they could well attack other Bedullin bands – ones smaller than this. Then there's the matter of Seley el'then. I don't like the fact that he's their captive.'

'You know Selethen?'Will asked.

The Aseikh nodded. 'We've fought together against the Tualaghi. He's a good man. A brave fighter. More important, he's an honest man – a man I trust. Those are good qualities to have in a Wakir. There's always the possibility that another man might not be so fair-minded. And a lot of Arridi resent us. They see us as interlopers in their country. Wakir Seley el'then has always treated us well. It might not suit us to have him replaced by someone who is not so honest or fair-minded.'

A small flame of hope was starting to burn in Will's chest as the Aseikh continued to analyse the situation.

'Are you saying you'll…?' he began but once more, Umar made that palm outward gesture to silence him.

'And there are two more points to consider. One: you have become a friend of the Bedullin. You saved my grandson's life and you behaved well in the matter of the race. My people like you, Will. And we take friendship seriously.'

'You said two points,' Will interposed.

Umar shook his head, his expression very serious. 'As Jamil told you, it was his fault that your friends were captured. If he had not been so clumsy, the Tualaghi would never have known they were there. His fault, his failing, becomes the failing of the tribe as a whole. This weighs very heavily on Jamil's mind… and my own.'

Will hardly dared to hope that what he was beginning to think might be true. Tentatively, as if by being too positive he might cause the idea to dissolve and blow away on the wind, he said: 'So you're saying you… '

He couldn't bring himself to finish the statement. Umar did it for him.

'I'm saying we're all agreed. We're going to rescue Seley el'then and your friends from the Veiled Ones.' He smiled at the elated young man beside him. 'Of course, you're welcome to come along with us if you wish.'
