“I’m glad you remember that, dear,” he said. “Now, Una, do try to remember all you can as I go along with my story... Well, I rode over alone, never telling anybody at Wrode where I was going, nor giving your step-father any reason of any sort to expect me. I trusted entirely to finding him busy with his new invention. When I reached The Grange, I came up the drive unperceived, and looking in at the library window, saw your father alone there. He was pottering over his chemicals. That gave me the clue. I left my bicycle under the window, tilted up against the wall, and walked in without ringing, going straight to the library. Nobody saw me come: nobody saw me return, except one old lady on the road, who seemed to have forgotten all about it by the time of the inquest.”
(I nodded and gave a start. I knew that must have been Aunt Emma.)
“Except yourself, Una, no human soul on earth ever seemed to suspect me. And that wasn’t odd; for you and your father, and perhaps Minnie Moore, were the only people in the world who ever knew I was in love with you or cared for you in any way.”
“Go on,” I said, breathless. “And you went into the library.”
“I went into the library,” Jack continued, “where I found your father, just returned from enjoying his cigar on the lawn. He was alone in the room—”
“No, no!” I cried eagerly, putting in my share now; for I had a part in the history. “He WASN’T alone, Jack, though you thought him so at the time. I remember all, at last. It comes back to me like a flash. Oh, heavens, how it comes back to me! Jack, Jack, I remember to-day every word, every syllable of it!”
He gazed at me in surprise.
“Then tell me yourself, Una!” he exclaimed. “How did you come to be there? For I knew you were there at last; but till you fired the pistol, I hadn’t the faintest idea you had heard or seen anything. Tell me all about it, quick! There comes in MY mystery.”
In one wild rush of thought the whole picture rose up like a vision before me.
“Why, Jack,” I cried, “there was a screen, a little screen in the alcove! You remember the alcove at the west end of the room. It was so small a screen, you’d hardly have thought it could hide me; but it did—it did—and all, too, by accident. I’d gone in there after dinner, not much thinking where I went, and was seated on the floor by the little alcove window, reading a book by the twilight. It was a book papa told me I wasn’t to read, and I took it trembling from the shelves, and was afraid he’d scold me—for you know how stern he was. And I never was allowed to go alone into the library. But I got interested in my book, and went on reading. So when he came in, I went on sitting there very still, with the book hidden under my skirt, for fear he should scold me. I thought perhaps before long papa’d go out for a second, to get some plates for his photography or something, and then I could slip away and never be noticed. The big window towards the garden was open, you remember, and I meant to jump out of it—as you did afterwards. It wasn’t very high; and though the book was only The Vicar of Wakefield, he’d forbidden me to read it, and I was dreadfully afraid of him.”
