This I did not like at all, for the going of these arrows brought the danger to our very door, as it were. Nor did the captain, for he himself kept watch over us for the rest of that night, and afterwards there was always a sentry in the passage that led to our room.
We were silent as we lay down again, and sleep was long in coming. I puzzled over all this, for beside the taking of the arrows there was the question of who the slayer of Tregoz might be, and who had written the letter that should have warned us.
In all truth, it was not good to sleep in the moonlight!
Somewhat of the same kind Owen was thinking, for of a sudden he said to me: "Those arrows were meant for me, Oswald. Did you note what the man said about my not sleeping in my wonted place?"
"Ay, but I did not know that you had slept on this side. Since I came back, at least, you have not done so."
Owen smiled.
"No, I have not," he said; "but in the old days that was always my place, and you will mind that there I slept on the night we first were here together. That was of old habit, and I only shifted to this side when you came back, because I knew that you would like the first light to wake you. Every sentry who crosses the window on the rampart can see in here if it is light within, but he could not tell that we had changed places, for the face of the sleeper is hidden."
Then he laughed a little, and added:
"In the old days when I was in charge of the palace this face of the ramparts was always the best watched, because the men knew that if I waked and did not see the shadow of the sentry pass and repass as often as it should, he was certain to hear of it in the morning. Tregoz would know that old jest. I suppose Dunwal may have had some hand in taking the arrows hence."
"It is likely enough," I answered. "He will have to pay for his brother's deed tomorrow, in all likelihood, also. But who wrote the letter, and who slew Tregoz?"
