"There's a fellow seen the ladder and run back for a policeman," Bull whispered hoarsely.

"Then hustle! Hustle!" whispered Greg.

The heavy man moved with a surprising celerity and noiselessness. Rough as was his exterior there was a gentle strain in him; he gathered up Amy as tenderly and unselfconsciously as if she had been a little child.

Bianca had ceased to struggle, and in his eagerness to follow the movements of the other man Greg relaxed his vigilance for a second. With a sudden cat-like twist she freed her face from his hand. A piercing shriek escaped her.

Greg quickly silenced her, but the mischief was done. After a second's breathless silence an uproar arose through the house. The nurse ran to the door and rattled it and beat upon it. Other doors opened and slammed, and running feet were heard throughout the house. In different parts of the house the insane patients infected with the excitement began to scream.

Bianca, encouraged by the sounds of approaching help, began to struggle with redoubled energy. She fought with every fiber of her being, like a cat in a snare. Greg was more than a match for her in strength, but scarcely in quickness. She got her head free again, and screamed:

"They're taking her out of the window. Go to the street!"

A voice in the hall said: "Break in the door!"

Running footsteps receded down the hall.

Bull had disappeared with Amy. It was no time for Greg to linger. If Bull did make him a signal, he couldn't hear it in that uproar. Releasing Bianca he ran for the bathroom window. Springing up, she followed, screaming incessantly.
