He referred again to one of the papers he had taken out.

'Yes, give the packet to Mr. Palmer,' he repeated.

'Which you intend to do?' Bertie asked.

'Certainly. At the same time, I may tell you that I have written a very strong letter to Mrs. Emsworth, protesting against her making use of me in—in private matters of this kind. I am a busy man'—and he looked at his watch—'I have no taste for other people's intrigues.'

Bertie thought intently for a moment. If he gave up the letter, he would be powerless in the future to prove anything with regard to the blackmail. The fact that he had drawn a cheque for £10,000 to Bilton was in itself nothing to show that he had done so under threats, especially if, as it suddenly occurred to him, Bilton was, if not in league with Mrs. Emsworth, at any rate cognizant of her action. On the other hand, if he refused, he had to risk that letter of his being sent to Mr. Palmer. He had been unable to face that risk before, and it was as unfaceable now. But the idea that Bilton was concerned in this was interesting. It had been suggested by the slight over-emphasizing of the fact that he was busy, by the looking at his watch. That was, however vaguely, threatening; it implied time was short, or that he himself was concerned in Bertie's acceptation of the ultimatum.

Bilton sat down again and tapped with his fingers on the table.

'Excuse me, Lord Keynes,' he said, 'but no purpose is served by our sitting here like this. You will, of course, please yourself in this matter. Here is the packet for you if you decide one way; there is the letter-box if you decide the other.' The speech was well-chosen, and left no room for doubt in Bertie's mind that the letter-box would be used. He took the desired document from his pocket.

'Here is the cheque,' he said, 'and here is the letter. The latter, you say, you are going to verify. I, on my side, I suppose, may verify what you give me.'

Bilton appeared to consider this for a moment.

'There was nothing said about that,' he remarked, 'but I feel certain that the lady would be willing to let you receive proof of her honourable dealing with you.'
