She unbuckled the belt and tried again. The next rung was a foot higher and the throw more difficult. Even this small effort was exhausting in her present state and she made herself take time. Every unsuccessful throw made the next more difficult. She didn't count the number of attempts, but at last the buckle fell over the rung and dropped towards her. When it snaked within reach she found that she could only just buckle the strap. The next rung would be too high. If this one broke, it would be the end.

But the rung held. She had no clear memory of the last half hour of the climb but at last she reached the ladder and strapped herself firmly to the uprights. For the first time she was physically safe. As long as the ladder held she needn't fear falling. She let herself relax into brief unconsciousness. But then the wheels of the mind which had been spinning blissfully free, took hold again and she began to think. She knew that she had no hope of moving the heavy wooden cover unaided. She stretched out both hands and pushed against it but it didn't shift, and the high concave dome made it impossible for her to brace her shoulders against the wood. She would have to rely on outside help and that wouldn't come till daylight. It might not come even then, but she pushed the thought away. Sooner or later someone would come. She could hope to hold on, thus strapped, for several days. Even if she lost consciousness there was a chance that she would be rescued alive. Miss Markland knew that she was at the cottage; her things were still there. Miss Markland would come.

She gave thought to how she could attract attention. There was room to push something between the boards of wood if only she had something sufficiently stiff to push. The edge of the buckle was possible provided she strapped herself more tightly. But she must wait until the morning. There was nothing she could do now. She would relax and sleep and await rescue.

And then the final horror burst upon her. There would be no rescue. Someone would be coming to the well, coming on quiet and stealthy feet under the cover of darkness. But it would be her murderer. He had to return; it was part of his plan. The attack, which at the time had seemed so astonishingly, so brutally stupid, hadn't been stupid at all. It was intended to look like an accident. He would come back that night and remove the well cover again. Then, some time next day or within the next few days, Miss Markland would blunder through the garden and discover what had happened. No one would ever be able to prove that Cordelia's death wasn't an accident. She recalled the words of Sergeant Maskell: 'It isn't what you suspect; it's what you can prove.^’ But this time would there even be suspicion? Here was a young, impulsive, over-curious young woman living at the cottage without the owner's authority. She had obviously decided to explore the well. She had smashed the padlock, drawn back the lid with the coil of rope which the killer would leave ready to be found, and tempted by the ladder, had let herself down those few steps until the final rung broke beneath her. Her prints and no one else's would be found on the ladder, if they took the trouble to look. The cottage was utterly deserted; the chance that her murderer would be seen returning was remote. There was nothing she could do but wait until she heard his footsteps, his heavy breathing, and the lid was drawn slowly back to reveal his face.

After the first intensity of terror, Cordelia waited for death without hope and without further struggle. There was even a kind of peace in resignation. Strapped like a victim to the uprights of the ladder she drifted mercifully into brief oblivion and prayed that it might be so when her killer returned, that she might not be conscious at the moment of the final blow. She had no longer any interest in seeing her murderer's face. She wouldn't humiliate herself by pleading for her life, wouldn't beg for mercy from a man who had strung up Mark. She knew that there would be no mercy.

But she was conscious when the well lid began slowly to move. The light came in above her bowed head. The gap widened. And then she heard a voice, a woman's voice, low, urgent and sharp with terror.

'Cordelia!'

She looked up.

Kneeling at the rim of the well, her pale face immense and seeming to float disembodied in space like the phantasm of a nightmare, was Miss Markland. And the eyes which stared into Cordelia's face were as wild with terror as her own.

Ten minutes later Cordelia was lying slumped in the fireside chair. Her whole body ached and she was powerless to control her violent shivering. Her thin shirt was stuck to her wounded back and every shift of movement was pain. Miss Markland had put a light to the kindling and was now making coffee. Cordelia could hear her moving to and fro in the little kitchen and could smell the stove as it was turned high and, soon, the evocative aroma of coffee. These familiar sights and sounds would normally have been reassuring and comforting, but now she was desperate to be alone. The killer would still return. He had to return, and when he did, she wanted to be there to meet him. Miss Markland brought in the two mugs and pressed one into Cordelia's shivering hands. She stumped upstairs and came down with one of Mark's jumpers which she wound round the girl's neck. Her terror had left her, but she was as agitated as a young girl sharing her first half-shameful adventure. Her eyes were wild, her whole body trembled with excitement. She sat down directly in front of Cordelia and fixed her with her sharp inquisitive eyes.

'How did it happen? You must tell me.'

Cordelia had not forgotten how to think.

'I don't know. I can't remember anything that happened before

I hit the water. I must have decided to explore the well and lost my balance.'

'But the well lid! The lid was in place!'

'I know. Someone must have replaced it.'

'But why? Who would have come this way?'

'I don't know. But someone must have seen it. Someone must have dragged it back.'

She said more gently:

'You saved my life. How did you notice what had happened?'

'I came to the cottage to see if you were still here. I came earlier today but there was no sign of you. There was a coil of rope – the one that you used, I expect – left in the path and I stumbled over it. Then I noticed that the lid wasn't quite in place and that the padlock had been smashed.'

'You saved my life,' said Cordelia again, 'but please go now. Please go. I'm all right, really I am.'

'But you aren't fit to be left alone! And that man – the one who replaced the lid – he might return. I don't like to think of strangers snooping around the cottage and you here alone.'

'I'm perfectly safe. Besides, I have a gun. I only want to be left in peace to rest. Please don't worry about me!'

Cordelia could detect the note of desperation, almost of hysteria, in her own voice.

But Miss Markland seemed not to hear. Suddenly she was on her knees in front of Cordelia and pouring out a spate of high, excited chatter. Without thought and without compassion, she was confiding to the girl her terrible story, a story of her son, the four-year-old child of herself and her lover, who had broken his way through the cottage hedge and fallen into the well to his death. Cordelia tried to shake herself free from the wild eyes. It was surely all a fantasy. The woman must be mad. And if it were true, it was horrible and unthinkable and she could not bear to hear it. Sometime later she would remember it, remember every word, and think of the child, of his last terror, his desperate cry for his mother, the cold suffocating water dragging him to his death. She would live his agony in nightmares as she would relive her own. But not now. Through the spate of words, the self-accusations, the terror recalled, Cordelia recognized the note of liberation. What to her had been horror, to Miss Markland had been release. A life for a life. Suddenly Cordelia could bear it no longer. She said violently:
