This was the hiding figure in my dream, the link hitherto wanting in my reveries concerning River Hall. I had been looking for this—waiting for it; I understood at last; and yet, when Munro mentioned the name of the man who had thought it worth his while to watch my movements, I shrunk from the conclusion which forced itself upon me.
"Must we go on to the end with this affair?" I asked, after a pause, and my voice was so changed, it sounded like that of a stranger to me.
"We do not yet know what the end will prove," Munro answered; "but whatever it may be, we must not turn back now."
"How ought we to act, do you think?" I inquired.
"We ought not to act at all," he answered. "We had better wait and see what his next move will be. He is certain to take some step. He will try to get you out of this house by hook or by crook. He has already striven to effect his purpose through Miss Elmsdale, and failed. It will therefore be necessary for him to attempt some other scheme. It is not for me to decide on the course he is likely to pursue; but, if I were in your place, I should stay within doors at night. I should not sit in the dark near windows still unshuttered. I should not allow any strangers to enter the house, and I should have a couple of good dogs running loose about the premises. I have brought Brenda with me as a beginning, and I think I know where to lay my hand on a good old collie, who will stay near any house I am in, and let no one trespass about it with impunity."
"Good heavens! Munro, you don't mean to say you think the man would murder me!" I exclaimed.
"I don't know what he might, or might not do," he replied. "There is something about this house he is afraid may be found out, and he is afraid you will find it out. Unless I am greatly mistaken, a great deal depends upon the secret being preserved intact. At present we can only surmise its nature; but I mean, in the course of a few days, to know more of Mr. Harringford's antecedents than he might be willing to communicate to anyone. What is the matter with you, Hal? You look as white as a corpse."
"I was only thinking," I answered, "of one evening last week, when I fell asleep in the drawing-room, and woke in a fright, imagining I saw that horrid light streaming out from the library, and a face pressed up close to the glass of the window on my left hand peering into the room."
"I have no doubt the face was there," he said, gravely; "but I do not think it will come again, so long as Brenda is alive. Nevertheless, I should be careful. Desperate men are capable of desperate deeds."
The first post next morning brought me a letter from Mr. Craven, which proved Mr. Harringford entertained for the present no intention of proceeding to extremities with me.
