‘Ah, that’s better,’ said the Inspector.

‘But I didn’t go!’ Sandford’s voice rose high and excited. ‘I didn’t go! I felt it would be much better not. I was returning to town tomorrow. I felt it would be better not—not to meet. I intended to write from London and—and make—some arrangement.’

‘You are aware, sir, that this girl was going to have a child, and that she had named you as its father?’

Sandford groaned, but did not answer.

‘Was that statement true, sir?’

Sandford buried his face deeper.

‘I suppose so,’ he said in a muffled voice.

‘Ah!’ Inspector Drewitt could not disguise the satisfaction. ‘Now about this “walk” of yours. Is there anyone who saw you last night?’

‘I don’t know. I don’t think so. As far as I can remember, I didn’t meet anybody.’

‘That’s a pity.’

‘What do you mean?’ Sandford stared wildly at him. ‘What does it matter whether I was out for a walk or not? What difference does that make to Rose drowning herself?’

‘Ah!’ said the Inspector. ‘But you see, she didn’t. She was thrown in deliberately, Mr Sandford.’

‘She was—’ It took him a minute or two to take in all the horror of it. ‘My God! Then—’

He dropped into a chair.

Colonel Melchett made a move to depart.

‘You understand, Sandford,’ he said. ‘You are on no account to leave this house.’

The three men left together. The Inspector and the Chief Constable exchanged glances.

‘That’s enough, I think, sir,’ said the Inspector.

‘Yes. Get a warrant made out and arrest him.’

‘Excuse me,’ said Sir Henry, ‘I’ve forgotten my gloves.’

He re-entered the house rapidly. Sandford was sitting just as they had left him, staring dazedly in front of him.

‘I have come back,’ said Sir Henry, ‘to tell you that I personally, am anxious to do all I can to assist you. The motive of my interest in you I am not at liberty to reveal. But I am going to ask you, if you will, to tell me as briefly as possible exactly what passed between you and this girl Rose.’

‘She was very pretty,’ said Sandford. ‘Very pretty and very alluring. And—and she made a dead seat at me. Before God, that’s true. She wouldn’t let me alone. And it was lonely down here, and nobody liked me much, and—and, as I say she was amazingly pretty and she seemed to know her way about and all that—’ His voice died away. He looked up. ‘And then this happened. She wanted me to marry her. I didn’t know what to do. I’m engaged to a girl in London. If she ever gets to hear of this—and she will, of course—well, it’s all up. She won’t understand. How could she? And I’m a rotter, of course. As I say, I didn’t know what to do. I avoided seeing Rose again. I thought I’d get back to town—see my lawyer—make arrangements about money and so forth, for her. God, what a fool I’ve been! And it’s all so clear—the case against me. But they’ve made a mistake. She must have done it herself.’
