‘You’ve no doubt now that she did,’ said Mr Satterthwaite.

‘No. I’ve no doubt now. I saw her face, Satterthwaite, when she looked at me. I knew then that what you’d said was truth. But why?’

‘Greed, I suppose,’ said Mr Satterthwaite. ‘She hadn’t any money of her own, I believe. Her husband, Christopher Eden, was a nice chap by all accounts but he hadn’t anything in the way of means. But Tom Addison’s grandchild has got big money coming to him. A lot of money. Property all around here has appreciated enormously. I’ve no doubt that Tom Addison will leave the bulk of what he has to his grandson. She wanted it for her own son and through her own son, of course, for herself. She is a greedy woman.’

Mr Satterthwaite turned his head back suddenly.

‘Something’s on fire over there,’ he said.

‘Good lord, so it is. Oh, it’s the scarecrow down in the field. Some young chap or other’s set fire to it, I suppose. But there’s nothing to worry about. There are no ricks or anything anywhere near. It’ll just burn itself out.’

‘Yes,’ said Mr Satterthwaite. ‘Well, you go on, Doctor. You don’t need me to help you in your tests.’

‘I’ve no doubt of what I shall find. I don’t mean the exact substance, but I have come to your belief that this blue cup holds death.’

Mr Satterthwaite had turned back through the gate. He was going now down in the direction where the scarecrow was burning. Behind it was the sunset. A remarkable sunset that evening. Its colours illuminated the air round it, illuminated the burning scarecrow.

‘So that’s the way you’ve chosen to go,’ said Mr Satterthwaite.

He looked slightly startled then, for in the neighbourhood of the flames he saw the tall, slight figure of a woman. A woman dressed in some pale mother-of-pearl colouring. She was walking in the direction of Mr Satterthwaite. He stopped dead, watching.

‘Lily,’ he said. ‘Lily.’

He saw her quite plainly now. It was Lily walking towards him. Too far away for him to see her face but he knew very well who it was. Just for a moment or two he wondered whether anyone else would see her or whether the sight was only for him. He said, not very loud, only in a whisper,

‘It’s all right, Lily, your son is safe.’

She stopped then. She raised one hand to her lips. He didn’t see her smile, but he knew she was smiling. She kissed her hand and waved it to him and then she turned. She walked back towards where the scarecrow was disintegrating into a mass of ashes.
