CHAPTER SEVEN  I Hear of the Wild Birds

I saw an old green felt hat, and below it lean tweed-clad shoulders. Then I saw a knapsack with a stick slung through it, as the owner wriggled his way on to a shelf. Presently he turned his face upward to judge the remaining distance. It was the face of a young man, a face sallow and angular, but now a little flushed with the day's sun and the work of climbing. It was a face that I had first seen at Fosse Manor.

I felt suddenly sick and heartsore. I don't know why, but I had never really associated the intellectuals of Biggleswick with a business like this. None of them but Ivery, and he was different. They had been silly and priggish, but no more--I would have taken my oath on it. Yet here was one of them engaged in black treason against his native land. Something began to beat in my temples when I remembered that Mary and this man had been friends, that he had held her hand, and called her by her Christian name. My first impulse was to wait till he got up and then pitch him down among the boulders and let his German accomplices puzzle over his broken neck.

With difficulty I kept down that tide of fury. I had my duty to do, and to keep on terms with this man was part of it. I had to convince him that I was an accomplice, and that might not be easy. I leaned over the edge, and, as he got to his feet on the ledge above the boiler-plates, I whistled so that he turned his face to me.

'Hullo, Wake,'I said.

He started, stared for a second, and recognized me. He did not seem over-pleased to see me.

'Brand!' he cried. 'How did you get here?'

He swung himself up beside me, straightened his back and unbuckled his knapsack. 'I thought this was my own private sanctuary, and that nobody knew it but me. Have you spotted the cave? It's the best bedroom in Skye.' His tone was, as usual, rather acid.

That little hammer was beating in my head. I longed to get my hands on his throat and choke the smug treason in him. But I kept my mind fixed on one purpose--to persuade him that I shared his secret and was on his side. His off-hand self-possession seemed only the clever screen of the surprised conspirator who was hunting for a plan.

We entered the cave, and he flung his pack into a corner. 'Last time I was here,' he said, 'I covered the floor with heather. We must get some more if we would sleep soft.' In the twilight he was a dim figure, but he seemed a new man from the one I had last seen in the Moot Hall at Biggleswick. There was a wiry vigour in his body and a purpose in his face. What a fool I had been to set him down as no more than a conceited fidneur!

He went out to the shelf again and sniffed the fresh evening. There was a wonderful red sky in the west, but in the crevice the shades had fallen, and only the bright patches at either end told of the sunset.

'Wake,' I said, 'you and I have to understand each other. I'm a friend of Ivery and I know the meaning of this place. I discovered it by accident, but I want you to know that I'm heart and soul with you. You may trust me in tonight's job as if I were Ivery himself.'

He swung round and looked at me sharply. His eyes were hot again, as I remembered them at our first meeting.

'What do you mean? How much do you know?'

The hammer was going hard in my forehead, and I had to pull myself together to answer.

'I know that at the end of this crack a message was left last night, and that someone came out of the sea and picked it up. That someone is coming again when darkness falls, and there wi
