Thomas had certainly shown good taste in his selection, for his Sarah was a very pretty little girl,—a slight active figure, a bright clear complexion, brown hair waving back off her forehead, a cheerful smile, large speaking eyes with a little touch of sauciness in them—which I fancied would sometimes vex and puzzle Thomas, who was a steady matter-of-fact young groom, not a little—and a very prettily cut nose and mouth. I was altogether very much taken with her appearance.

I asked them to take seats, and Sarah at once began:—

"Miss Ashleigh, I am told by"—and here she paused a little, coloured, and ended by telling a story and saying—"Mary, that I could be of service to you. I can only say that I shall be glad to do so by any means in my power; we are all at Harmer Place very sorry at your losing your rights, and should rejoice to see you restored to them."

Sarah expressed herself so well that I was really quite surprised. I thanked her for her offer, and said, "You can, indeed, do us a service which may turn out of great importance. Now I do not disguise from you, it will cost you your place if you are discovered; but I need not say that we will take care that you shall be no loser by that. Now I will at once tell you how we stand at present, and what we want to find out. We know, or at least are nearly sure, that the will exists, and that it is with some other papers large enough to fill a good-sized box. Now we strongly believe that this box is hidden away in a secret room we know to exist in the house; and what we want to find out is, where is that secret room? It must be a pretty good size—I mean much larger than a mere closet—because we know people used to lay hid there in old times." Sarah nodded, as much as to say that she had heard legends of the "priest's chamber." "Now, Sarah, the first thing we want to discover is the whereabouts of this room—and this can only be done in one way. I want the exact dimensions—that is to say, the measure, the height, length, and breadth, of every room, passage, closet, and staircase in the old part of the house; because as this room existed in the old time, it is only in the central part of the house, which was the original building, that the secret chamber need be looked for. When I have got all these measurements, and put them all down upon paper, I shall see where there is a space to fill up. Do you understand?"

Sarah did not quite understand; so I got a sheet of paper, drew a rough plan of a house, and explained the matter more fully.

Sarah understood now, and at once entered into it with all her heart.

"You see," I said, "we want the exact position of the doors, windows, and chimneys. Here is a small pocket-book and pencil: take one page for each room; mark down first in this way, the extreme length and breadth, then the positions of the doors and windows thus, and put 'in small figures' their distances from each other."

I then showed her a small plan of Harmer Place, which I had drawn from my recollection of it, and Sarah understood perfectly what she had to do.

"Make a notch the length of a yard on the handle of your broom," I said, "and measure the exact length of the bottom of your apron. With your broom you can get the height of the room, and with your apron the other measurements, so that you will be able to get all the sizes; and even if you are disturbed, no one would have the slightest idea of what you are doing."

I then asked her to measure the room we were in, and to make a little sort of plan of it, and I found her so quick and intelligent, that I felt certain she would execute her task with sufficient accuracy to enable us to find out where the secret room was situated.
