"Yes, yes," I whispered eagerly.

"Would you play the spy in order to save me from calamity?"

"Do not put it that way," I said bitterly; "but I would do anything that a gentleman could do to serve you. You have made me love what is honourable, you have made me hate that which is mean."

"Would it be mean to discover the plottings of my enemies?" she asked tremulously.

"No, no," I answered eagerly. "Such a work would be worthy of any man. Command me, Mistress Nancy. Tell me of the man who has plotted against you, and I will go to him and tear his secret from him."

"Wait!" was her answer.

At this moment I heard a low rapping at the door.

She wandered slowly around the room for some minutes speaking never a word; then turning to me suddenly she said:

"Follow me if you would serve me."
