I was looking in some wonderment at this opening and marvelling over the extravagant hospitality of those old days which necessitated such a number of rooms in a private gentleman's home, when I heard a door open and two voices speaking. One was rough and careless, unmistakably that of William Knollys. The other was slow and timid, and was just as unmistakably that of the man who had driven me to this house the day before. They were talking of some elderly person, and I had good sense enough not to allow my indignation to blind me to the fact that by that elderly person they meant me. This is important, for their words were not without significance. "How shall we keep the old girl out of the house till it is all over?" was what I heard from William's surly lips. "Lucetta has a plan," was the hardly distinguishable answer. "I am to take----" That was all I could hear; a closing door shut off the remainder. Something, then, was going on in this house, of a dark if not mysterious character, and the attempts made by these two interesting and devoted girls to cover up the fact, by explanations founded on their poverty, had been but subterfuges after all. Grieved on their account, but inwardly grateful to the imprudence of their more than reckless brother, for this not-to-be-mistaken glimpse into the truth, I slowly descended the stairs, in that state of complete self-possession which is given by a secret knowledge of the intentions formed against us by those whose actions we have reason to suspect. Henceforth I had but one duty--to penetrate the mystery of this household. Whether it was the one suspected by Mr. Gryce or another of a less evil and dangerous character hardly mattered in my eyes. While the blight of it rested upon this family, eyes would be lowered and heads shaken at their name. This, if I could help it, must no longer be. If guilt lay at the bottom of all this fear, then this guilt must be known; if innocence--I thought of the brother's lowering brow and felt it incompatible with innocence, but remembering Mr. Gryce's remarks on this subject, read an instant lecture to myself and, putting all conclusions aside, devoted the few minutes in which I found myself alone in the dining-room to a careful preparation of my mind for its duty, which was not likely to be of the simplest character if Lucetta's keen wits were to be pitted against mine.
