She went on working at it, exposing more and more of the faded ochre line where it disappeared into the rubble. I was holding the torch for her and she was working so hard I could smell the warmth of her, dust clinging to her damp skin, her face a pale mask. Then I heard it again and I gripped her arm to silence her. 'Somebody called,' I said.
She turned, the piece of rock she had just prised loose still in her hand, her head on one side. Even her hair was covered with a grey film. 'I don't hear anything.' She brushed my hand away, thrusting the chunk of stone behind her.
'I'm going through,' I said.
She didn't seem to hear me, leaning forward again, brushing gently with her fingers at the section of wall she had just exposed.
I pushed her out of the way and crawled forward over the rubble, turning on my side. I was just starting to wriggle into the gap feet-first when, back up the slope of the cave, I saw a glimmer of light. It grew rapidly brighter, hardening into the beam of a torch, and a moment later Gareth Lloyd Jones was crouched beside us.
'Where's Soo?' I asked him. 'You said you'd stay with her.'
'Waiting in the car.' He was breathing hard. 'I came up to tell you.' He was kneeling now, his face close to mine as I lay with only my head and shoulders protruding from the hole. 'How far does it go, right through to the cliff face?' He thought I had already explored the continuation of the cave.
'I don't know,' I told him. 'I'm just going to find out.'
'But you've been here for a quarter of an hour or more.'
Petra and I started to explain about the mark on the wall of the cave, both of us speaking at once, but he brushed our explanation aside. 'Have you heard something? Anybody moving about?'
'I thought I heard somebody call out,' I said. 'And before that there was something like the murmur of voices. It could have been the sea. Or it could have been squatters.' And I started to tell him about the villa near Binicalaf Nou.
'Voices,' he said. 'That's what you heard. There's somebody in there. I came up to warn you.' Instead of waiting in the bush-shadowed dark of that track, he and Soo had decided to drive down to the cove. They had left the car and were walking down through the loose sand of the beach towards the sea when they had seen a light on the cliff face away to the left. 'We were just at the point where somebody had made a little trough in the rock and put up a notice to say the water in it was from a spring and good to drink. You know where I mean?'
'Yes, of course. But where exactly was the light? In one of the cave entrances?'
'Yes, and it wasn't there long. It wasn't very bright either, more like a hurricane lamp, or even a candle. A slightly yellowish light, and low down, only a little above the sea.'
I asked him whether it could have been the riding light of a ship, or perhaps the masthead light of a sailing boat, but he said definitely not. With the moon so bright it would have been impossible for them not to have seen a vessel if there had been one there. 'Even with the cliff face in shadow, the dark hole where we saw the light was plainly visible. And then suddenly it wasn't there any more.' He didn't know whether it had been snuffed out, switched off, or whether somebody had moved it away from the aperture. 'I was looking seaward at the time, so was Soo. We both thought somebody must be signalling a boat in through the entrance. But there was nothing coming into the cove. Then, when I looked back at the cave, it was gone. That's when I decided to come up here and warn you. They're in one of the caves, but whether it's this one, '
'Only one way to find out.' I started wriggling through again, using my elbows, but he stopped me.
'No. If they knew we were here…' I could see his face in the diffused light of our torches. It was shining with sweat and his mouth was moving uncontrollably.
What's the matter?'
'Nothing. It's just…' He reached out, gripping hold of my shoulder. 'Leave it till morning, man. Please. Then we can come back with one or two of your employees, or the police. If you go in now — ' He shook his head, his voice trembling.
Christ! The man was scared. 'They're only squatters,' I told him. 'Nothing to worry about. And if this is the cave they're in, then they'll have heard us. I'm going in,' I said again. 'Soon find out if there's anyone here or not.'
What about your wife? And Petra here? If they know you're in the cave…' He stopped there, the rest of his words bitten back and his face set. 'All right,' he said. 'I'll come with you.'
'You don't have to.'
'Yes, I do. I'll come with you,' he said again, his voice quite obstinate now. He seemed suddenly to have made up his mind, and when I suggested he go back to the car and wait with Soo, he shook his head. 'If you're going to try and reach the cliff entrance, then I'm coming with you. It's my duty.' It seemed an odd way of putting it, but I didn't think about it then. I was already working my way in over the roof fall and he was coming after me headfirst. The fall was only about ten metres through and then we were crouched low and moving down a steep incline, the breeze quite strong on our faces and our torches showing alow arched tunnel swinging away to the right. As soon as we rounded the bend we could see the cliff-face entrance, a pale rectangle of moonlight, and we could stand upright, for here, at the sea-worn end, the cave was much larger. There were camp beds ranged against the walls, four of them with sleeping bags, wooden packing cases for tables and seats and a paraffin stove that looked as though it had come out of some derelict fishing boat. The stove was for heating as well as cooking, and there were dishcloths, a couple of shirts too, hung on a line above the pipe that carried the fumes out to the cliff face. The whole place was equipped for living in, quite comfortably equipped, and propped against the wall was a heavy timber frame covered with plywood that had been tailored to fit the entrance. It had a little window and great iron bolts that slotted into sockets drilled in the rock so that even in a sou'westerly gale the place would be quite snug.
The noise of the sea was loud now, the dishcloths swaying in the wind. I went over to the entrance and leaned out. The cliff was sheer, a drop of about twenty feet or so to a narrow rock ledge that formed a sort of natural quay with deep water beyond, and the cave's entrance had been beautifully worked into scrolled pillars either side supporting a rather Greek-style portico. Inside, ledges had been carved out of both walls, a place for ornaments or household crockery. Whoever had originally fashioned the cave as a home must have been a real craftsman, a stonemason probably, everything so professionally done. 'All you need is a rope ladder,' Lloyd Jones said, peering down to the narrow ledge of rock below.
'And a yacht,' I added. 'Champagne cooling in the further recesses of the cave and a beautiful girl sunbathing down there in a bikini.' Or perhaps not in a bikini, just lying there on that ledge, nude in the moonlight.
He didn't laugh, and nor did I, for I found myself thinking of Petra, how well she would fit the picture in my mind. 'Nobody here,' I said.
'No.' He sounded relieved. 'But they've been here.' He had moved back from the entrance, his voice puzzled as he probed with his torch.
I was puzzled, too, the cave showing every sign of recent occupation and nobody there. The broken remains of an old cupboard full of cans of food. There were biscuits and cornflakes in a rusty cake tin, flour, rice, dried fruit, plastic containers with water, and those dishcloths and shirts hung up to dry.
'Where are the heads?' he asked.
The heads?'
'It's all right throwing the slops out into the cove. But if I want to shit, where do I do it?' He swung his torch back up the way we had come. That was how we found the offshoot cave. It was quite narrow, the entrance draped with an old piece of sacking so covered with dust it was virtually the same colour as the surrounding wall, and when we pulled it aside, there it was, a chemical loo.
