"The packet you took in Madison Square an hour ago; the packet you locked in this safe! And if you like I'll tell you just what that packet is!"
"This is some mistake, some very sad mistake," she had the effrontery to declare. Her arm still clung to me. Her face was very close to mine as she went on. "I can explain everything, if you will only give me the time—everything! I can show you where you are wrong, and how you may suffer through a mistake like this!"
"We can talk all that over later," I promptly told her, for I was beginning to suspect that her object now was merely to kill time, to keep me there, in the hope of some chance discovery. I peered about the room, wondering what would be the quickest way out of my dilemma.
"What are you going to do?" she asked as she watched me shove a chair over against the wall, directly beside the safe.
"I'm going to seat you very comfortably in this very comfortable chair," I informed her, "and in this equally comfortable corner directly behind the safe door. And at the first trick or sign of trouble, I'm afraid I'm going to make a hole right through one of those nice white shoulders of yours!"
She sat down without being forced into the chair. Her alert and ever-moving eyes blazed luminously from her dead-white face. I knew, as I thrust the huge key in the safe lock and turned it back that she would have to be watched, and watched every moment of the time.
I had already counted on the safe door, as it swung back, making a barrier across the corner in which she sat. This I found to be the case. I took a second precaution, however, by shoving a tilted chair-back firmly in under the edge of the safe lock.
I knew, as I stooped before the open strong box, that she could make no sudden move without my being conscious of it. I also knew that time was precious. So I reached into the depths of the almost empty safe and lifted out a number of papers neatly held together by a rubber band.
These I placed on the safe top. Then I snapped off the band and examined the first document. On the back of it, neatly inscribed in French, was the eminently satisfactory legend: "Plans and Specifications; Bs. Lake Torpedo Company, Bridgeport." The next packet was a blue print of war projectiles, and on the back of it was written: "Model Tracings, through Jenner, from the Bliss & Company Works—18—Self-Projectors."
The third packet carried no inscription. But as I opened it I saw at a glance what it was. I knew in a moment that I held before me the governmental wheel-code of wireless signals in active service. It was the code that had been stolen from Lieutenant Palmer. The fourth and last paper, I found, was plainly the dummy which had been taken from the same officer that night in Madison Square. The case was complete. The chase was over and done.
