Harry, keeping his father's orders well in mind, crouched a little lower and waited.

Presently he heard a slight rustling, and he knew that Skelly's men were among the dwarf pines on the lawn.

The rustling continued and came nearer.

Harry glanced at his father, who was behind a pillar not ten feet away.
"Who are you, and what do you want ?" called Colonel Kenton into the darkness.
There was no answer and the rustling ceased.

Harry heard nothing but the gentle fall of the rain.
"Speak up!" called the colonel once more.
