‘We didn’t meet, but you saw me at the inquest at Luce Manor. I am Inspector Tanner of Scotland Yard, and I have been put in charge of the case.’

The Inspector, who was watching the other keenly, noticed a sudden look flash across his face and then disappear. It was not exactly a look of alarm. Rather was it that of a man brought suddenly face to face with a danger he had long recognised—a kind of bracing of himself to meet a crisis which was at last at hand. But his manner was free from any trace of anxiety as he motioned his visitor to a chair.

‘Ah yes,’ he said, ‘of course. I remember now. My cousin, Austin Ponson, told me about you. So you fear my uncle’s end might have been suicide? It is a horrible idea, and you won’t mind my saying that I cannot but think you are wrong. He was not at all that kind of man.’

‘So I am beginning to think, Mr Ponson. But orders are orders. I have been told to investigate and report, and I must do so.’

Cosgrove agreed and they conversed for some time. Tanner asked a good many questions, but without learning anything of interest. Then at last he came to the real object of his visit. Speaking very much as he had done to Austin, he asked Cosgrove to state his own movements on the fatal Wednesday night. Cosgrove, unlike Austin, got on his high horse.

‘Really, Inspector, I think that’s a little too much. Why should I tell you anything of the kind? What has it to do with the affair?’

Tanner could be direct enough when he saw cause.

‘Why this, Mr Ponson,’ he answered, still watching the other keenly. ‘As you must see, the possibility of suicide involves that of murder also. The question I have asked you is asked in such cases as a matter of course to every one interested.’

Cosgrove started slightly at the last words.

‘Interested?’ he repeated. ‘What do you mean by that? Do you think I was interested?’
