black of cave entrances. Almost immediately the ground began to rise and we lost sight of them. We were moving across the steep side of the ravine, still following traces of a path. It reached a point where we could see the waters of the cove entrance black in shadow, then it doubled back on itself, steeper now as we moved out on to the detritus caused by weathering of the cliff face above. Once Petra stopped to point the torch I had lent her at skid marks on the surface of the scree. ‘Looks as though a bed or a crate, something heavy, has been hauled up here. Did you notice the imprint of feet down in the bottom?’
    She scrambled up the steep bend, following the pathacross loose stone until it reached the base of the cliff where there were bushes growing, the entrance to the cave above screened by a dense thicket. Again there were indications of recent use, twigs snapped, small branches bent back, and in the black hole of the entrance itself the dry dust of the floor was scuffed by feet. ‘That’s not me,’ she said, flashing her torch. ‘I’ve only been into this cave once.’ Again there were skid marks as though a box had been dragged along the ground. ‘Watch the roof.’ She went on ahead of me, the height of the cave gradually lessening until I had to stoop. The sides of it were very smooth. ‘I’m not sure,’ her voice echoed back at me, ‘whether this has been scooped out by surface water making its way to the sea or by the sea itself.’
    There were any number of caves around the coast, most of them well below sea level, some reached only by water-filled sumps or chimneys. Looking back at the moonlit half-circle of the entrance, I realised we were striking into the cliff at an oblique angle. We were also moving downwards. ‘You’ve got to remember,’ I said, ‘that when the ice-caps and the glaciers melted at the end of the last ice age the level of the sea rose very considerably.’
    â€˜I know. The best of the caves are thirty to sixty feet down.’
    â€˜Is that what your diving friend says?’
    â€˜Bill Tanner? Yes. He says there’s a marvellous one by Arenal d’en Castell, a sort of blue grotto, enormous. He’s promised to take me down, sometime when I’m not fossicking around, as he calls it.’
    I switched off my torch, looking back up the slope. The entrance was no longer visible, only the glimmer of moonlight on stone showing ghostly pale. The roof was getting very low, though at that point the walls had pulled back as though this were some sort of expansion chamber. Like the other caves in the Cales Coves area, the walls here were water-worn and the upper entrance high above sea level. It must have been formed at some period whenthe island’s rainfall was very much greater than it was now. The pounding of the sea so far below could never have done it by air pressure alone.
    â€˜Here’s the roof fall.’ Petra’s voice came to me distorted and booming. ‘I’m just about there. But mind your head.’ And then I heard her swear.
    â€˜What is it? Have you hurt yourself?’ I snapped my torch on, swinging it to send the beam lancing ahead down the tunnel.
    â€˜No. Nothing like that.’ She was crouched down, her torch on the left-hand wall. In front of her the cave appeared to have collapsed, loose rock piled almost to the roof, rubble everywhere.
    â€˜What is it then?’ I scrambled down the slope.
    â€˜Look! It’s gone. The bastards have put their bloody shovels right across it. They’ve scraped it clean away. Why did they have to enlarge the hole?’ She was leaning forward, brushing at the rock face with her fingers, the fine limestone dust sifting on to the stone below and almost white in the torchlight. She sat back on her haunches, cursing softly under her breath. ‘If only I’d sent you a message and come straight back here and waited.
