I stopped and waited for some obliterating noise before venturing the last thrust that would send the bolt free of the loosening socket. It came with the sudden sound of steps and the turning off of the running tap. The door had been forced open and stood an inch or two from the jamb before the steps sounded again.

I waited, with my heart in my mouth, wondering if anything had been overheard, if anything had been discovered. It was only then, too, that the enormity of my offense came home to me. I was a house-breaker. I was playing the part of a midnight burglar. I was facing a situation in which I had no immediate interest. I was being confronted by perils I had no means of comprehending. But I intended to get inside that room, no matter what it cost.

I heard, as I stood there, the sound of a drawer being opened and closed. Then came a heel-click or two on the wooden floor, and then an impatient and quite audible sigh. There was no mistaking that sigh. It was as freighted with femininity as though I had heard a woman's voice. And nothing was to be gained by waiting. So I first leaned my iron rod silently against the door corner. Then, taking a deep breath, I stepped quickly and noiselessly into the lighted room.

I stood there, close beside the partly opened door, blinking a little at the sudden glare of light. There was an appreciable interval before the details of the scene could register themselves on my mind.

What I saw was a large and plainly furnished room. Across one corner stood a rolltop desk, and from the top of this I caught the glimmer of a telephone transmitter. In the rear wall stood two old-fashioned, low-silled windows. Against this wall, and between these two windows, stood a black iron safe.

Before the open door of this safe, with her back turned to me, was the woman in the cream-colored gown. It was quite plain that she was not yet aware of my presence.

She had thrown her hat and cape aside, and was at the moment bending low over the dark maw of the opened safe, reaching into its recesses with one white and rounded arm. I stood there watching her, wondering what move would be most effective. I made no sound; of that I was certain. Yet some sixth sense must have warned her of my presence. For without rhyme or reason she suddenly stood erect, and swinging about in her tracks, confronted me.

Her face, which had been a little flushed from stooping, went white. She stared at me without speaking, her eyes wide with terrified wonder. I could see her lips slowly part, as the shock of what she beheld began to relax the jaw muscles along the olive-white cheek.

I stared back at her with a singularly disengaged mind. I felt, in fact, very much at my ease, very much the master of the situation. As an opponent, I could see, she would be more than mysterious. She would, in fact, be extremely interesting.

Her next move, however, threw a new complexion on the situation. For she unexpectedly let her hand dart out to the wall beside her, just behind the safe top. As she did so, I could hear the snap of a switch button; the next moment the light went out. It left the room in impenetrable darkness.
