Willis waited for some minutes to let the captain get clear away, then leaving his hiding-place and again keeping on the grass, he passed down the drive and out on to the road. He was profoundly disappointed. He had failed in his purpose, and the only ray of light in the immediate horizon was that last remark of Archer’s. If it meant, as he presumed it did, that the men were to communicate by the secret telephone at eleven in the morning, all might not yet be lost. He might learn then what he had missed tonight.

It seemed hardly worth while returning to Hull. He therefore went to the Raven Bar in Ferriby, knocked up the landlord, and by paying four or five times the proper amount, managed to get a meal and some food for the next day. Then he returned to the deserted cottage, he let himself in, closed the door behind him, and lying down on the floor with his head on his arm, fell asleep.

Next morning found him back at his post at the broken window, with the telephone receiver at his ear. His surmise at the meaning of Archer’s remark at the study window proved to be correct, for precisely at eleven he heard the familiar: “Are you there?” which heralded a conversation. Then Beamish’s voice went on:

“I have talked this business over with Benson, and he makes a suggestion which I think is an improvement on our plan. He thinks we should have our general meeting in London immediately after I have interviewed Madeleine Coburn. The advantage of this scheme would be that if we found she possessed really serious knowledge, we could immediately consider our next move, and I could, if necessary, see her again that night. Benson thinks I should fix up a meeting with her at say 10.30 or 11, that I could then join you at lunch at 1.30, after which we could discuss my report, and I could see the girl again at 4 or 5 o’clock. It seems to me a sound scheme. What do you say?”

“It has advantages,” Archer answered slowly. “If you both think it best, I’m quite agreeable. Where then should the meetings be held?”

“In the case of Miss Coburn there would be no change in our last night’s arrangement; a private sitting-room at the Gresham would still do excellently. If you’re going to town you could fix up some place for our own meeting—preferably close by.”

“Very well, I’m going up on Tuesday in any case, and I’ll arrange something. I shall let Benson know, and he can tell you and the others. I think we should all go up by separate trains. I shall probably go by the 5.3 from Hull on the evening before. Let’s see, when will you be in again?”

“Monday week about midday, I expect. Benson could go up that morning, Bulla and I separately by the 4, and Fox, Henri, and Raymond, if he comes, by the first train next morning. How would that do?”

“All right, I think. The meetings then will be on Tuesday at 11 and 1.30, Benson to give you the address of the second. We can arrange at the meeting about returning to Hull.”

“Righto,” Beamish answered shortly, and the conversation ended.
