'Ask what? Do you have to talk like a marriage guidance counsellor?'
'Ask why you told the police you were here at nine. You weren't. I was. After the Copleys left I had a sudden need to see you. I tried the telephone but got only the answer-phone. I didn't leave a message; there was no point. I walked down. The cottage was empty. The light was on in the sitting room and the kitchen and the door was locked. I called out for you. The record player was on, very loud. The cottage was filled with triumphant music. But there was no one here.'
Alice sat in silence for a moment. Then she said calmly: 'I went for a walk to enjoy the moonlight. I didn't expect a casual caller. There are never casual callers except you, and I thought that you were in Norwich. But I took the obvious precaution against an intruder, I locked the door. How did you get in?'
'With your key. You can't have forgotten, Alice. You gave me a key a year ago. I've had it ever since.'
Alice looked at her and Meg saw in her face the dawning of memory, chagrin, even, before she turned briefly away, the beginning of a rueful smile. She said: 'But I had forgotten; completely. How extraordinary! It might not have worried me, even if I had remembered. After all, I thought you were in Norwich. But I didn't remember. We've got so many keys to the cottage, some here, some in London. But you never reminded me that you had one.'
'I did once, early on, and you told me to keep it. Like a fool I thought that the key meant something: trust, friendship, a sign that Martyr's Cottage was always open to me. You told me that I might one day need to use it.'
And now Alice did laugh aloud. She said: 'And you did need to use it. How ironic. But it isn't like you to come in uninvited, not while I wasn't here. You never have before.'
'But I didn't know you weren't here. The lights were on and I rang and I could hear the music. When I rang the third time and you still didn't come I was afraid that you might be ill, unable to summon help. So I unlocked the door. I walked into a surge of wonderful sound. I recognized it, Mozart's Symphony in G minor. It was Martin's favourite. What an extraordinary tape to choose.'
'I didn't choose it. I just turned on the player. What do you think I should have chosen? A requiem mass to mark the passing of a soul I don't believe in?'
Meg went on as if she hadn't heard: 'I walked through to the kitchen. The light was on here too. It was the first time I'd been in this room on my own. And suddenly I felt like a stranger. I felt that nothing in it had anything to do with me. I felt that I had no right here. That's why I went away without leaving you any message.'
Alice said sadly: 'You were quite right. You had no right here. And you needed to see me so badly that you walked alone over the headland before you knew that the Whistler was dead?'
'I didn't walk in fear. The headland is so deserted. There's nowhere anyone can lurk, and I knew when I reached Martyr's Cottage I'd be with you.'
'No, you're not easily frightened are you? Are you frightened now?'
'Not of you but of myself. I'm frightened of what I'm thinking.'
'So the cottage was empty. What else is there? Obviously there is something else.'
Meg said: 'That message on your answerphone; if you'd really received it at ten past eight you would have telephoned Norwich station and left a message for me to ring back. You knew how much the Copleys disliked the thought of going to their daughter. No one else on the headland knew that. The Copleys never spoke of it and nor did I, not to anyone except you. You would have rung, Alice. There could have been an announcement over the station loudspeaker and I could have driven them home. You would have thought of that.'
Alice said: 'One lie to Rickards which could have been a matter of convenience, a wish to avoid trouble, and one instance of insensitive neglect. Is that all?'
'The knife. The middle knife in your block. It wasn't here. It meant nothing at the time, of course, but the block looked odd. I was so used to seeing the five carefully graded knives, each in its sheath. It's back now. It was back when I called in on the Monday after the murder. But it wasn't here on the Sunday night.'
She wanted to cry out: 'You can't be going to use it! Alice, don't use it!' Instead she made herself go on, trying to keep her voice calm, trying not to plead for reassurance, understanding.
'And next morning, when you telephoned to say that Hilary was dead, I didn't say anything about my visit. I didn't know what to believe. It wasn't that I suspected you; that would have been impossible for me, it still is. But I needed time to think. It was late morning before I could bring myself to come to you.'
'And then you found me here with Chief Inspector Rickards and heard me lying. And you saw that the knife was back in the block. But you didn't speak then and you haven't spoken since, not even, I presume, to Adam Dalgliesh.'
It was a shrewd thrust. Meg said: 'I've told no one, how could I? Not until we'd spoken. I knew that you must have had what seemed to you a good reason for lying.'
'And then, I suppose, slowly, perhaps unwillingly, you began to realize what that reason might be?'
'I didn't think you'd murdered Hilary. It sounds fantastic, ludicrous even to speak those words, to think of suspecting you. But the knife was missing and you weren't there. You did lie and I couldn't understand why. I still can't. I wonder who it is you're shielding. And sometimes – forgive me, Alice – sometimes I wonder whether you were there when he killed her, kept guard, stood there watching, might even have helped him by cutting off her hair.'
Alice sat so still that the long-fingered hands resting in her lap, the folds of her shift, might have been carved in stone. She said: 'I didn't help anyone – and no one helped me. There were only two people on that beach, Hilary Robarts and I. I planned it alone and I did it alone.'
For a moment they sat in silence. Meg felt a great coldness. She heard the words and she knew that they were true. Had she, perhaps, always known? She thought: I shall never be with her in this kitchen again, never again find the peace and security which I found in this room. And there fell into her mind an incongruous memory; herself sitting quietly in the same chair and watching while Alice made short pastry; sieving the flour on to a marble slab, adding the squares of soft butter, breaking in the egg, her long fingers delicately dabbling the mixture, drawing in the flour, lightly forming the glistening ball of dough. She said: 'They were your hands. Your hands tightening the belt round her throat, your hands cutting off her hair, your hands slicing that L into her forehead. You planned it alone and you did it alone.'
Alice said: 'It took courage, but perhaps less than you would imagine. And she died very quickly, very easily. We shall be lucky to go with so little pain. She hadn't even time to feel terror. She had an easier death than most of us can look forward to. And as for what followed, that didn't matter. Not to her. Not even much to me. She was dead. It's what you do to the living that takes the strong emotions, courage, hatred and love.'
She was silent for a moment, then she said: 'In your eagerness to prove me a murderess, don't confuse suspicion with proof. You can't prove any of this. All right, you say the knife was missing, but that's only your word against mine. And if it was missing, I could say that I went for a short walk on the headland and the murderer saw his chance.'
'And put it back afterwards? He wouldn't even know that it was there.'
'Of course he would. Everyone knows that I'm a cook, and a cook has sharp knives. And why shouldn't he put it back?'
'But how would he get in? The door was locked.'
'There's only your word for that. I shall say that I left it open. People on the headland usually do.'
Meg wanted to cry out: 'Don't, Alice. Don't begin planning more lies. Let there at least be truth between us.' She said: 'And the portrait, the smashed window, was that you too?'
'Of course.'
