Take her out and get a doctor.

What sort of a hell's melee is this, anyway ?" "Oh," moaned Rita, who was torn and fainting, almost unconscious from sheer terror.
"I'll kill her!" screamed Aileen.

"I'll murder her! I'll murder you too, you dog! Oh"-- she began striking at him--"I'll teach you how to run around with other women, you dog, you brute!" Cowperwood merely gripped her hands and shook her vigorously, forcefully.
"What the devil has got into you, anyway, you fool ?" he said to her, bitterly, as they carried Rita out.

"What are you trying to do, anyway--murder her?
Do you want the police to come in here?
Stop your screaming and behave yourself, or I'll shove a handkerchief in your mouth! Stop, I tell you! Stop! Do you hear me?
This is enough, you fool!" He clapped his hand over her mouth, pressing it tight and forcing her back against him.

He shook her brutally, angrily.
