"Oh, but it wasn't my business to! Of course I had guessed what you were doing here—"

"What?"

"Trying to rid our island of traitors of course! I had interfered with you once, but I wasn't going to do it again. In fact I tried to reassure you by talking of my walk with Mr. Merton."

"Miss Rendall," I said, "I am a child at this game. You did reassure me. I have been as clay in your hands. But tell me one thing more. Why on earth did you come out with me on that first walk—armed with that horse pistol?"

"Oh, you saw it then!" she exclaimed.

"I almost smelt the slow match! But why did you do it?"

"Well, you know what I thought you were then, and there was no one else to go with you."

"Then you actually went out with a spy at night to keep an eye on him—and shoot him if he spied?"

"I should probably have missed!" she laughed.

I was quite ready to swear by Jean Rendall now. Talk of pluck! I never heard of a more fearless performance!
