The deed was over before I could move.  I sprang forward.  Deschamps laughed, and turned to me.  I closed with her.  She scratched and bit, and she was by no means a weak woman.  At first I feared that in her fury she would overpower me.  At length, however, I managed to master her; but her strength was far from exhausted, and she would not yield.  She was mad; time was passing.  I could not afford to be nice in my methods, so I contrived to stun her, and proceeded to tie her hands with my handkerchief.  Then, panting, I stood up to survey the floor.

I may be forgiven, perhaps, if at that frightful crisis I was not perfectly cool, and could not decide on the instant upon the wisest course of action to pursue.  Sir Cyril was insensible, and a little circle of blood was forming round the dagger; Deschamps was insensible, with a dark bruise on her forehead, inflicted during our struggle; Rosa was insensible—­I presumed from excess of emotion at the sudden fright.

I gazed at the three prone forms, pondering over my handiwork and that of Chance.  What should be the next step?  Save for my own breathing, there was a deathlike silence.  The light from the empty room above rained down upon us through the trap, illuminating the still faces with its yellow glare.  Was any other person in the house?  From what Sir Cyril had said, and from my own surmises, I thought not.  Whatever people Deschamps might have employed to carry messages, she had doubtless dismissed them.  She and Rosa had been alone in the building.  I can understand now that there was something peculiarly attractive to the diseased imagination of Deschamps in the prospect of inviting her victim to the snare, and working vengeance upon a rival unaided, unseen, solitary in that echoing and deserted mansion.  I was horribly perplexed.  It struck me that I ought to be gloomily sorrowful, but I was not.  At the bottom of my soul I felt happy, for Rosa was saved.

It was Rosa who first recovered consciousness, and her movement in sitting up recalled me to my duty.  I ran to Sir Cyril, and, kneeling down so as to screen his body from her sight, I drew the dagger from its sheath, and began hastily, with such implements as I could contrive on the spur of the moment, to attend to his wound.

“What has happened?” Rosa inquired feebly.

I considered my reply, and then, without turning towards her, I spoke in a slow, matter-of-fact voice.

“Listen carefully to what I say.  There has been a plot to—­to do you injury.  But you are not hurt.  You are, in fact, quite well—­don’t imagine anything else.  Sir Cyril Smart is here; he’s hurt; Deschamps has wounded him.  Deschamps is harmless for the moment, but she may recover and break out again.  So I can’t leave to get help.  You must go.  You have fainted, but I am sure you can walk quite well.  Go up the stairs here, and walk along the hall till you come to the front door; it is not fastened.  Go out into the street, and bring back two gendarmes—­two, mind—­and a cab, if you can.  Do you understand?”
