“Hurt? Are you hurt?” he panted eagerly, as she sat up on the hard floor and with her hands smoothed back the hair from his hot, aching head.

“I feel so weak and dizzy,” she answered. “And I'm afraid--oh, Allan, I'm afraid! But, no, I'm not hurt.”

“Thank God for that!” he breathed fervently. “Can you untie these infernal knots? They're almost cutting my hands off!”

“Here, let me try!”

And presently the girl set to work; but even though she labored till her fingers ached, she could not start the tight and water-soaked ligatures.

“Hold on, wait a minute,” directed he. “Feel in my right-hand pocket. Maybe they forgot to take my knife.”

She obeyed.

“They've got it,” she announced. “Even if they don't know the meaning of revolvers, they understand knives all right. It's gone.”

“Pest!” he ejaculated hotly. Then for a moment he sat thinking, while the girl again tried vainly to loosen the hard-drawn knots.

“Can you find the iron door they shoved us through?” asked he at length.
