She touched a spot on the door, and immediately it swung on its hinges. I followed her into the passage, and up a long flight of stairs.

"Whither are we going?" I asked presently.

"To a secret place in the house," was her answer; "you will be safer there."

"But you told me I was safe yonder."

"Will you not trust me?" she said. "You said you would serve me."

I followed her without another word. Had she told me to go to my death, I think I should have obeyed.

Presently she opened the door of an apartment.

"Enter there," she said; "do not make a sound of any sort. Wait in perfect silence until I return."

I entered.
