In due course he pulled up, and she discovered that they had come out upon a clear space of lawn, close beside the featureless, looming bulk of a dark and silent building.

An admonitory grasp tightened upon her fingers, and she caught his singularly penetrating yet guarded whisper:

"This is the back of the house—the service-entrance. From this door a broad path runs straight to the main service gateway; you can't mistake it; and the gate itself has a spring lock, easy enough to open from the inside. Remember this in event of trouble. We might become separated in the darkness and confusion…."

Gently returning the pressure, "I understand," she said in a whisper.

Immediately he drew her on to the house, pausing but momentarily before a wide doorway; one half of which promptly swung open, and as soon as they had passed through, closed with no perceptible jar or click. And then Lanyard's flash-lamp was lancing the gloom on every hand, swiftly raking the bounds of a large, panelled servants' hall, until it picked out the foot of a flight of steps at the farther end. To this they moved stealthily over a tiled flooring.

The ascent of the staircase was accomplished, however, only with infinite care, Lanyard testing each rise before trusting it with his weight or the girl's. Twice he bade her skip one step lest the complaints of the ancient woodwork betray them. In spite of all this, no less than three hideous squeals were evoked before they gained the top; each indicating a pause and wait of several breathless seconds.

But it would seem that such servants as had been left in the house, in the absence of its chatelaine, either slept soundly or were accustomed to the midnight concert of those age-old timbers; and without mischance, at length, they entered the main reception-hall, revealed by the dancing spot-light as a room of noble proportions furnished with sombre magnificence.

Here the girl was left alone for a few minutes, while Lanyard darted above-stairs for a review of the state bedchambers and servants' quarters.

With a sensation of being crushed and suffocated by the encompassing dark mystery, she nerved herself against a protracted vigil. The obscurity on every hand seemed alive with stealthy footfalls, whisperings, murmurings, the passage of shrouded shapes of silence and of menace. Her eyes ached, her throat and temples throbbed, her skin crept, her scalp tingled. She seemed to hear a thousand different noises of alarm. The only sounds she did not hear were those—if any—that accompanied Lanyard's departure and return. Had he not been thoughtful enough, when a few feet distant, to give warning with the light, she might well have greeted with a cry of fright the consciousness of a presence near her: so silently he moved about. As it was, she was startled, apprehensive of some misadventure, to find him back so soon; for he hadn't been gone three minutes.

"It's quite all right," he announced in hushed accents—no longer whispering. "There are just five people in the house aside from ourselves—all servants, asleep in the rear wing. We've got a clear field—if no excuse for taking foolish chances! However, we'll be finished and off again in less than ten minutes. This way."
