"I'll sit up again to-night, Leila," he said.
"Not to-night," I objected. "This sort of adventure requires one to be at one's best. If you take my advice you will go to bed early and have a good stretch of sleep, so that you will be quite fresh by to-morrow. There will be a moon for some nights still."
"Why do you keep harping on the moon?" said Phil rather crossly, for him.
"Because—I have some idea that it is only in the moonlight that—that anything is to be seen."
"Bosh!" said my brother politely—he was certainly rather discomposed—"we are talking at cross-purposes. You are satisfied——"
"Far from satisfied," I interpolated.
"Well, convinced, whatever you like to call it—that the whole thing is supernatural, whereas I am equally sure it is a trick; a clever trick I allow, though I haven't yet got at the motive of it."
"You need your nerves to be at their best to discover a trick of this kind, if a trick it be," I said quietly.
