What if he should let her bleed to death! Oh sister, oh lover, come, or she would die of horror, if not the knife! And Katie—why didn't she come! At this moment the sound of the train whistle in the distance broke on the stillness of the night. How could she gain ten minutes more? The man had not noticed the sound.

"What do you wish?" she asked sweetly, "What shall I get for you?"

"Only a handkerchief and a basin," he replied coolly, still fingering a sharp lancet. "You are not afraid? Good girl; now for my crowning victory!"

As a sleep-walker she procured the articles and bared her arm. Tenderly he was binding it above the blue veins, when she said in winning tones:

"Let me tell you how I think would be the best way to do this—may I?" and she fixed her large eyes upon him in entreaty. He paused, and she continued:

"Now let me tie your arm in the same way. You open your own vein with the lancet, then open mine, and quickly after mix the two while the blood is warm. Do you see? You can't fail if you do it that way."

He looked at her. She did not flinch.

"Perhaps you are right; very well."

She arose as deliberately as she dared and went to her dresser for another handkerchief. At the moment she opened the linen case her ears, strained to the utmost, caught a murmur from below stairs. Turning quickly to see if the man also had heard, the door was pushed open and Katie's neat cap filled the aperture.
