She obeyed him with mechanical precision; but when he took the lamp from her listless hand, turning it upward to examine her face, he read in her eyes awakening realization and horror.

He snapped off the light. Still grasping her hand, he seated himself on the floor with his back to the open safe. He drew her down. For a moment he thought she would resist, then she yielded and sank passively to the cushion at his side.

"Why?" she asked.

"They will be here," he said. "There is no way out except through that door which they will use. It is safer to wait here. Why don't they come?"

"They are careful," she whispered back. "They will come slowly. They will take no chances."

He felt the quick shaking of her body.

"I know what I have done," she said, "what I have done to you."

He realized that his hand still grasped hers. He released it gently.

"I understand a little," he answered, "but if you cared enough to accomplish this madness for him, you should have been even less kind to me than you were this afternoon."

"Perhaps," she answered. "Oh, I don't know. I don't know. I was so young. I loved him so much, and my father said his murderer would never be punished—justice must fail. Maybe it was my Italian blood, but I swore over his body the day they buried him that, if there was no other way, I would get justice for the poor boy. We were practically certain it was this gang. I said nothing to my father. Through a girl I had helped I met Slim. It pleased his vanity to have a spy at headquarters. I made him trust me. But I couldn't find out who—Yet sooner or later I knew the time would come. That's why I worked so hard for to-night, why I wouldn't let anything interfere, because I thought in this room—Well! You see—Listen!"
