“My husband’s ancestors built the place. I am afraid you have been reading novels.”

“I saw a man prowling in the garden. And he disappeared into a stone wall.”

“One of the servants, probably.”

“If he was, he didn’t want to be seen.”

“Oh, probably he came to see one of the maids. I can’t watch them all the time.”

“You shouldn’t be so far away from everyone, it isn’t safe.”

“Don’t worry, Marshall,” she answered. She was so calm that, half convinced, I began to think that I had been making a lot of fuss over nothing, when a crash sounded behind her, like a small table going over, and one of the candles went out. I could tell that because the room was a shade darker after the crash than before. Helena did not move. I waited for her to look around, or make some explanation. She was silent.

“Very well,” I said. “Good night, Helena,” and turned away, a little hurt and angry. Then I remembered how fast and excitedly she had talked before dinner, and tried once more. “You’re sure you’re all right?”

“Believe me,” she answered, “I am in no need of protection, but thanks for coming, Marshall.” She closed the door, then. It was no affair of mine, of course, if she did not want it to be. Though I was her only living relative, I had never seen much of her. I was an outsider and an interloper. I went back to my room, and then down into the garden to find John. We sat again on the white bench where I had first seen the prowler.

A tiny crack of light showed down the center of a corner window, just above us. I decided that that must be one of Helena’s windows. That would be likely, for they overlooked the garden and the valley, too. A beautiful location. I showed John the point where I had last seen the figure that had so mysteriously disappeared. And then we both saw something that I had missed before. It lay just at the foot of the bush that I still felt must mask a secret entrance into the castle. A small square of white. We stooped together, and our heads bumped. John came up from the affray, rubbing his head, but with the paper. I am only five years older than John, but I was born a little slower.
