Still all was dark. I carefully examined the ground around the two stunted trees I have mentioned, and presently I caught sight of something which set my heart beating violently. I was on the point of making a closer examination of what I had already seen, when a ray of light shone from one of the windows and I could hear the sound of voices. Again looking around me eagerly, I saw what looked like a large clump of rhododendron bushes. These offered me not only a hiding-place, but a post of observation. I had scarcely crept between the leaves when the door of John Liddicoat's house opened and two people came out. They were the man and the woman whom I had seen that morning.
Almost at the same time the moon rose behind a distant hill, and a few minutes later the garden was flooded with its silvery light.
"Have you got it all?" It was a woman who spoke.
"Yes, all except ..." and I could not catch the last word.
They made their way towards the stunted trees, where they dropped the things they had brought. Then the man left the woman and appeared a little later bearing a light ladder.
I saw the man place his ladder against the tree and mount it, carrying something with him, what it was I could not tell. The moon had now risen high enough to enable me to see more plainly and to show me that the two worked swiftly and dexterously, as though they were accustomed to their work. Presently they had evidently finished, for they stood still and waited for something.
"I do not expect we shall get anything to-night." It was the woman who spoke.
"There is no knowing," replied the man; "besides, we have our orders. It is a calm night, too."
"Close on midnight," was the reply. "Anyhow, we must wait here until half-past twelve; if nothing comes by that time we shall hear nothing until to-morrow night. My word, if that fool of a fellow who lives in the hut on the cliff only knew! For my own part, I am not sure he does not suspect."
"I thought he was very guarded this morning," replied the man, "and I must use every means to make certain; if we bungle this we shall be in a bad way. Anyhow, he is closely watched night and day."
After this there was silence, save that I thought I heard a faint clicking noise. The minutes dragged heavily. It seemed as though nothing were going to happen. The moon rose higher and higher, revealing the outlines of the man and woman still more plainly, and presently I saw that their waiting had been rewarded. There was a clear repetition of the sounds I had heard previously. Then the woman said, "Have you got it?"
