With the slight gilt lamp in her hand she went out of the little rock chamber, listened a moment, and began to descend the steps.
"But the key ?" I asked, following her light footsteps with my heavier tread.
"It is in the door," she answered, and went on.
When we reached the bottom we found it as she had said.

The servant had left the key on the inside, and with some difficulty I turned the bolts.

We stood for one moment in the narrow space, where the lowest step was set close against the door.

Her eyes flashed strangely in the lamplight.
"How easy it would be!" I said, understanding her glance.

She nodded, and pushed me gently out into the street; and I closed the door, and leaned against it as she locked it.
"Good-night," she said from the other side, and I put my mouth to the key-hole.
