It burst open, revealing only an interior of darkness, but he turned quickly back to the automobile, threw wide its door and beckoned with peremptory command to the two dark figures sitting within.
They stepped out, Julie first, and entered the lodge.

John followed them, and there they stood, staring at one another until their eyes might grow used to the dusk and they could see their faces.

It was evident that Muller was not anywhere in the building, or he would have come at the sound of the machine.
John glanced toward a window set deep in a heavy timbered wall and admitting enough light to disclose a lantern and a box of matches on a shelf.

Still in his shrouding coat, cap and glasses he stepped forward, struck a match and lighted the lantern.

Driven by a sudden impulse, he swept off the cap and glasses and held up the light.
He saw Julie's face turn deadly pale.
