Alan acted wholly upon impulse. He thought that the girl was inside, alone. She might be able to help—
He knocked, very softly on the door.
"What you—" Charlie began.
"Sh!"
He knocked again.
It happened unexpectedly; yet Alan by instinct was ready for it.
The door abruptly opened!
It swung, just a few inches; a guttural voice sounded, speaking unintelligible words!
Whatever surprise it was to Alan, the Indian within was undoubtedly far more surprised. Alan stuck his foot into the door opening; he shoved violently with his powerful body, his shoulder against the door. It yielded; opened wide with a rush, knocking the Indian backward.
Alan burst into the room. The Indian, unarmed, recovered his balance to find himself staring at Alan's leveled revolver.
