Harriet stood motionless and watched. In her ignorance she thought that each thrust must end it, so impossible did it seem to turn aside, now this flashing blade, now that; but presently it was evident, even to her, that the fight was fiercer. The panting breaths came quicker, the blades rang more sharply. She wondered that the house had not been aroused, wondered that those passing in the streets had not heard this quarrel of steel with steel, and sought to know the reason. Then for the first time through long, long minutes her eyes wandered. The power which held her immovable and speechless was lessening, but the tension was not gone yet. Her eyes wandered, and her ears heard something besides the ringing steel. The curtains over the window shook a little, stirred by a breath of wind from the alley without. Then the window must have been left open! How was it no one without had heard the noise?
Crosby's back was to the window; he could not see that the curtains stirred, his ear caught no sound to startle him.
Rosmore, although he faced the window, saw nothing, heard nothing. His eyes were fixed upon those of his enemy, who was growing fiercer, more deadly every moment. The end was coming. Rosmore knew it, and felt weary. Every moment his enemy's point came nearer. It was parried this time and that, and again; but still it came. It touched him that time, not enough to scratch even, still it touched him! Next time! No, once more it was turned aside, and then it touched him again. It was nothing, but there was blood on his arm. In a moment that blade which had begun to dazzle him would be in his heart.
The curtains stirred again, floating out slightly into the room. Harriet's eyes turned to Rosmore, and saw the blood on his arm. She knew that this was the end. Then the curtains parted swiftly, and Crosby's blade fell with a clatter to the floor. For an instant he was struggling in the grasp of two men who had rushed upon him from behind, and was then borne to the ground. It was at this moment, too, that Harriet flung back the curtain from the door and stood in the room. Perhaps she expected Rosmore to make one late thrust at the falling man.
For a moment there was silence.
"Tie this handkerchief round my arm, mistress," said Rosmore; "the honours have gone against me."
She did as she was told.
"Shall we secure him, sir?"
"Yes, Sayers, but gently. I would not have him hurt. Forgive me, Crosby, I had no hand in this interruption; but, since it comes, I am glad to take advantage of it. What brought you here, Sayers?"
"Chance," was the answer. "We were wondering where the alley led to, saw the window unfastened, and heard the steel."
