Therefore, I told Fleming Stone all I knew of Victoria Van Allen, both before, during and after the occasion of her birthday party. He listened, with his deep eyes fixed on my face. "Most extraordinary!" he said, at last, after I had finished. "I never heard of such daring! To enter her own house when it was watched by the police--" "Only the post patrol, then," I reminded him. "She could easily manage between his rounds." "Yes, yes, I know. But you've put the whole thing in different focus. Tell me more." There was no more to tell, but I went over my story again, amplifying and remembering further details, until we had spent the whole evening. He egged me on by questions and his burning, eager eyes seemed to drink in my words as if they were so much priceless wisdom. And I told him, too, that I had promised to put Vicky's address book in the Chinese jar for her that very evening. "We'll do it!" he exclaimed, promptly. "She meant to meet you there, I'm sure, but I'm also sure she changed her mind about that, when she learned of my advent. However, we'll keep your promise." Acting at his instructions, I went with him over to Vicky Van's. It was about midnight, and as he had the address book with him, he kept possession of it. We went in the house, and in the dark, felt our way up to the music room. Stone put the book in the jar, and motioned for me to hide behind a sofa. He himself took up his vigil behind a window-curtain, of heavy brocade. He had planned all this, before we left my house, and no word was spoken as we took our places. His hope was that Vicky would come into the house late and go straight for her book and quickly out again. He had directed me to wait until she had really abstracted the book from the jar and then, as she was leaving the room, spring after her and stop her. I obeyed orders implicitly, and, as Stone had warned me, we had a bit of a wait. I grew cramped and tired, and at last I gave up all hope of Vicky's appearance. And then, she came! Silently, absolutely without sound, she glided in from the hall. My eyes, now accustomed to the semi-gloom of the room, could discern her figure as it approached the great vase. Softly, she raised the cover, she abstracted the book, and with noiseless touch was replacing the cover, when she threw back her head, as if she sensed our presence. I had made no move, nor had I heard a breath of sound from Stone, but Vicky knew some one was present. I knew that by her startled movement. She gave a stifled scream, and pushing the great jar off on the floor, where it crashed to pieces, she rushed out of the room and down stairs. "After her, Calhoun! Fly!" shouted Stone, and as he flung back the heavy curtains the street lights illuminated the scene. But as we avoided the broken fragments we bumped together and lost a few seconds in our recovery from the impact.
