Kane went to the table and helped himself to another 'drink. 'You don't know anything about this guy Cunningham, then?'

Skiros shrugged his great shoulders. 'I'm afraid not. When was he supposed to arrive here?' When Kane told him he frowned for a moment and then shook his head. 'No, I can't remember him.'

Kane swallowed his drink and walked to the door. 'I think I'll go and see Muller. He might have run across him.'

He opened the door and Skiros said, 'But why should you go to all this trouble, my friend? I confess I am puzzled.'

Kane turned and grinned. He held up one hand and rubbed his thumb across his fingers in the universal gesture that is readily understood in every corner of the world. 'For money,' he said. 'What else?'

When he emerged from the hotel into the street it was still quiet and deserted, but the sun enveloped him in an invisible cloak that caused the sweat to spring from every pore, soaking through his shirt and pants. He walked slowly along the shady side of the street towards Muller's house, frowning slightly as he considered his conversation with Skiros.

If Cunningham had landed in Dahrein, it was strange Skiros didn't know of it. It was a small town and not much escaped him. But perhaps Cunningham had never reached Dahrein? Perhaps he'd changed his mind? After all, there was only the letter to his wife to go on. On the other hand that theory didn't hold water. He'd left Aden on the mail boat - the British Consul had cor firmed that. He must have landed in Dahrein. Perhaps he'd already made arrangements to go up-country and hadn't bothered booking in at the hotel. From what his wife had said, he couldn't have had a great deal of money.

Muller's house was in a narrow alley on the north side of the harbour. The entrance was set in a high wall and Kane pulled on an ancient bell chain several times. As he waited for a response he thought about the German. Muller had arrived in Dahrein the first time about a year previously. A stiff, perfectly mannered Prussian, he was interested in graffiti - the ancient rock inscriptions which were to be found throughout the mountains. He constantly made long expeditions by truck, penetrating deep into some of the wildest country on the border. He seldom took more than two or three Arabs with him and carried no weapons. He was considered by the Musabein to be mad, and this probably accounted for his continued existence. No true believer would dare eternal h.e.l.l, by laying hands on one of the afflicted of Allah.

The door opened and an Arab servant in clean white robes stood to one side, bowing deeply as Kane entered. He moved into a pleasant courtyard in the centre of which a fountain sparkled in the sun. Above his head, a balcony jutted out from one of the first-floor windows and Muller appeared and looked down at him. A pleased smile appeared on his face and he waved cheerfully. 'Ah, Kane, my good friend. The very man. Come up - come up at once!'

Kane followed the servant inside the house. He led the way upstairs to a narrow corridor, opened a door and stood to one side, motioning Kane through.

Muller was standing beside a large table in his shirt sleeves. When he bowed he almost clicked his heels. He smiled. 'I have something that will interest you. I've taken a latex squeeze of an inscription I found in a gorge near Shabwa. Give me your opinion on it.'

Kane examined the long strip of rubber. The professor was using a new method of copying his inscriptions: a latex solution brushed on to the rock, hardened quickly in the sun and peeled away in a long strip carrying with it a perfect copy.

Kane examined the inscription with interest. After a moment he looked up. 'Quatabanian, isn't it?'

The German nodded. 'Yes, I found it on a rock face not far from an ancient camel trail. I haven't had time to translate it properly, but it seems to refer to a war with the Kingdom of Sheba sometime during the seventh century BC.'

Kane sat on the edge of the table. 'You know that's the third time you've been in the Shabwa area, to my knowledge, during the past four months. Don't you think you're asking for trouble?'

Muller snorted. 'I have no interest in who runs the country so long as I am left alone. The tribesmen know it and don't bother me.'

Kane shrugged. 'Don't say I didn't warn you. Tell me, have you run across any Europeans in the Shabwa area during the past couple of months?'

Muller looked at him in surprise. 'Only Jordan, that crazy fellow-countryman of yours. Why do you ask?'

'There's a woman in town looking for her husband,' Kane told him. 'An archaeologist called Cunningham. He's supposed to have gone up-country to Shabwa about two months ago. No one's heard of him since.'

The German threw back his head and laughed harshly.

'Nor are they likely to, if he went alone. But what did he want at Shabwa?'

Kane shrugged. 'I understand he was looking for graffiti, like you.'

'I can do without the compet.i.tion, thank you.' Muller got to his feet and walked across to the window, a frown on his face. 'No, I'm afraid I haven't come across this man.' He shook his head. 'It's rather strange. I'm sure I would have heard if there was another European in the mountains.'

Kane nodded. 'Yes, that's what I can't understand. Even Skiros hasn't heard of him, and that's saying something.'

Muller shrugged. 'I'm sorry I can't help you.'

'That's all right,' Kane said. 'I'm beginning to think the guy never arrived here in the first place.'

The German nodded. 'It certainly looks like it.'

Kane went back downstairs, and the servant appeared at once from the cool darkness of a rear corridor and escorted him to the door. When it had closed behind him, he stood for a moment in the hot street, thinking about his next move. There was really only one thing left to do for the moment. He could check with Captain Gonzalez. He would certainly remember if a European named Cunningham had landed from the mail boat during the past two months.

He walked back through the town the way he had come, pa.s.sed the hotel and continued along the waterfront towards the north jetty. The Spaniard's house was next to it and looked down over the beach. Kane knocked at the door and it was opened almost immediately by a heavily veiled woman.

She showed him into a cool, inner courtyard, where he found Gonzalez stretched comfortably on a divan, a can of beer in one hand, the contents of which he was pouring into a tall gla.s.s.

He looked up and said cheerfully, 'See, you have caught me in the act. Already I am becoming a slave to your American habits. Will you join me?'

Kane shook his head. 'Not this time if you don't mind.'

He sat on the end of the divan, pushing his cap to the back of his head, and Gonzalez said, 'It is not often you honour my humble house with a visit, Captain Kane. Presumably you are in need of my a.s.sistance.'

Kane grinned. 'As a matter of fact I am.'

An expression of complacency appeared on the Spaniard's face and he leaned back against the cushions with a sigh. 'Ah, sooner or later everyone comes to me. I trust you will not accuse me of pride if I tell you that few things happen in Dahrein that I do not get to know about sooner or later.'

Kane nodded. 'I know and that's why I'm here. There's a woman in town - a Mrs Cunningham.'

Gonzalez nodded. 'This is so. She got off the mail boat from Aden today.'

'She's looking for her husband. He wrote to her two months ago telling her he was coming to Dahrein. He intended to go up-country to Shabwa. She hasn't heard from him since.'

The Spaniard frowned. 'What was this man's name - Cunningham, you say?' He shook his head slowly. 'I'm afraid she must have made a mistake. No one by that name has landed in Dahrein.'

'Are you absolutely sure about that?' Kane demanded.

Gonzalez shrugged. 'How could I be mistaken? Do I not meet every boat?'

For a moment Kane was going to argue, but he decided it wasn't worth it. That the Spaniard didn't check half the boats he should was common knowledge in Dahrein. Getting him to admit that fact was something else entirely. He pulled his cap down over his eyes and sighed. 'Thanks anyway. It looks as if Mrs Cunningham made a mistake.'

Gonzalez nodded wisely. 'It is a thing women commonly do.'

Kane stood outside the house, as the door closed behind him, and looked out across the harbour to the launch. He could see Piroo squatting against the stern rail and knew that the Hindu would be watching him.

He felt tired - really tired. He slipped a hand into his hip pocket and pulled out the envelope Ruth Cunningham had given to him. He looked at it thoughtfully and came to a sudden decision. There was only one other person in Dahrein who might have some information about the elusive John Cunningham. That was Marie Ferret. He had to see her anyway, but his visit could wait until the evening when it was cooler.

He walked along to the end of the jetty and Piroo tumbled over the stern into the dinghy and sculled it towards him. Kane dropped down into the little boat and the Hindu started to pull back towards the launch. 'Any visitors while I've been away?'

Piroo shook his head. 'All is quiet, Sahib. It is too hot for any but a fool to be abroad.'

Kane grinned and the little Hindu's face clouded with dismay. 'I am sorry, Sahib,' he said. 'I have a foolish tongue.'

Kane shook his head and pulled himself up over the rail of the launch. 'No, I think you've hit the nail on the head this time, Piroo. I'm dead tired. I'm going below for a sleep. Wake me around eight, will you?'

Piroo nodded and Kane went below into the coolness of his cabin. He mixed a drink, stripped the clothes from his body and went and lay on the bunk, the envelope Ruth Cunningham had given him in his hand.
