She ought to be here; but I'm afraid she isn't." Sweetwater rapped again, this time with decided vehemence.
Suddenly in one of the uncurtained windows a face appeared.

They saw it, and both drew a deep breath.

The eyes were looking their way, but they were like ghost's eyes.

Without sight or speculation in them, they simply looked; then the face slowly withdrew, growing ghastlier every minute, and the window stared on, but the woman was gone.

Yet the door did not open.
"I hate to use force," objected Sweetwater.
Before answering, Mr.Gryce stepped to one side and cast a glance around the corner of the house in the direction of the gorge opening in the rear.
"There is something like a yard at the back," he announced, "but the fence which shut it in is so high and so protected by means of prickly underbrush that you would have difficulty in climbing it." "Just so at this end," called out Sweetwater after a short run to the left.
