The two girls then took their leave, and I really felt strong hope in the success of my plan—not indeed that it was mine, for it was Harry's idea entirely, and I only gave her the instructions he had previously given me.
After this, a small packet arrived every week, sent by Sarah, through Thomas, to his father, containing seven or eight leaves of the pocket-book.
In little more than a month we had all the measurements, and were enabled to make out the entire plan, in doing which, of course our previous knowledge of the house assisted us greatly. Papa assisted me in this. I had not, at first, told him anything of what I was doing, as I wished that, in case by any chance my scheme was detected, he should be able to say that he knew nothing about it. At last, however, I was obliged to let him into the secret, and when I told him, he was very much interested and pleased; and I do not think that I should ever have succeeded in putting the parts together, and certainly have never arrived at any accurate conclusion, without his assistance.
When it was done, we found the blank space precisely where we had anticipated that we should do. It is difficult to explain the exact position, but I will endeavour to do so.
On entering the house, from the front, one found oneself in a large square hall, from one side of which the library opened, and from the other the dining-room. Opposite to the front door was an immense fireplace, in which still stood two large iron dogs, and in which in winter a great wood fire always blazed; on one side of this fireplace, the grand staircase went up, and on the other a passage led down to a room which had originally been a drawing-room, but which, from its windows being at the back of the house, had been long since turned into a kitchen; the fireplace of this room stood back to back to the one in the hall. It was in the block contained in the square formed by the backs of the kitchen and hall, the staircase and the passage, that we came to the conclusion that the secret room must be, for, even allowing for immense thickness of masonry, there was yet a large space unaccounted for. On the floor above there was also a space, directly over this, considerably larger than would have been required for the chimneys of the hall and kitchen fire, even had there been two of them—which there were not, for Sarah found that the chimney of the hall made almost a right angle, and ran into the kitchen chimney.
Papa, after going very carefully into the measurements, came to the conclusion that the room itself was situated nearly over the hall fireplace; that it might be some seven or eight feet long, by five or six wide, and that it could be little over six feet high. He thought it was approached by some short staircase opening into the hall fireplace, or into one of the bedrooms above, which abutted on the vacant space on that floor. One of these rooms had been occupied by Herbert Harmer, and the other had been, and was still, Miss Harmer's room.
Indeed papa suspected both entrances to exist, as by them, in case of necessity, provisions could be so much more readily and secretly supplied, and escape made in some disguise from the one exit, should an entrance be forcibly made at the other.
"All this is mere guesswork, my dear; but when there is so much ground to go upon as we have got, one can guess very closely indeed to the truth."
"And where should you think, papa, that the entrance is most likely to be discovered?"
"Most likely in the hall fireplace. The back and sides, if I remember right, are formed of iron, with rude ornaments upon it. The mantelpiece, too, is of old oak, and is covered with carving; undoubtedly in some of all this the secret spring is concealed. The hall is the best place to try for another reason; early in the morning, and at various times indeed, Sarah might search among all these ornaments and knobs for the spring, and if any one came suddenly into the hall, her presence there would appear only natural; whereas in either of the bedrooms, and especially that of Mr. Harmer, which is not now in use, she could hardly be often without exciting suspicion."
Sarah came on the following Saturday evening, and I showed her the plan we had made, and explained to her where we thought the entrance was, and how she was most likely to find the secret spring.
Sarah was much pleased with the success which had so far attended her efforts, and promised to find the spring if it existed. She said she would get up half an hour before the other servants, and try every knob and roughness on or near the grate.
However, week after week rolled on, and every Saturday came a message, "No result;" and the week before Christmas she sent to say she had tried every possible place, but could not find any signs of it. I sent back in answer to ask her to try all the stones and bricks as far up the chimney as she could reach.
With Christmas, Polly came home from school, and this time to stop for good, for papa could not very well afford to keep her at so expensive a school as Grendon House; and indeed we wanted her bright face and happy laugh back again among us. Papa's practice was not very lucrative; it was a large, but not a good-paying one. A great proportion of it lay among the lower classes; in any serious cases among them he was always ready to give his time and skill. Indeed for the last three years, since there was an apparent certainty that we should be all so handsomely provided for, papa had purposely given up much of his paying practice. Many among the upper classes have the habit of calling in a medical man on the slightest pretext, and like him, indeed, to call regularly, and have an hour's chat on all sorts of subjects; this time papa could not spare, and indeed I know that he said to two or three of his very best patients,—
"You have nothing serious the matter with you. All you want is a little occasional medicine, and a good chat of a day to do you good and cheer you up; this I have no time to give you, when I have half a dozen dying people waiting anxiously for me. Send to Harper; he is a clever fellow; knows all about everything; will amuse you more than I do. He has a large family, and your money will be of use to him. If you get seriously ill, and want me, I will of course come to you."
So papa had gradually withdrawn himself from much of his paying practice; he had still an income sufficient to keep us comfortably, but it was not nearly what it had been four or five years before. However, he was quite content to work as he did, giving his skill and time to those who most required but were least able to pay for them.
Harry came home, too, a little before Christmas. He had finished his last piece of work, and had now obtained an appointment of £150 a year to superintend a railway in the course of construction in the north of Ireland.
The evening after Christmas Day I received a note from Sarah, saying, that that morning, she had, in feeling up the chimney, found a projecting knob immediately behind the mantelpiece; that on pressing this it went into the wall, and that every time it did so, she could hear a click, but that she could not find that anything else moved.
"Hurrah, Sarah!" Harry shouted when I read the note aloud; "we are on the right track. 'The king shall enjoy his own again!'" he sang in his stentorian way.
"I really do begin to think we are on the track," papa said. "You must tell Sarah that no doubt there is some other spring which must be pressed either together or before or after this; for generally there were two springs to these old hiding-places, in case one should be touched accidentally."
This I told Sarah, who came on the next Sunday evening to see me. She had rather began to despair before; but now that she had found something tangible she became quite enthusiastic, and said that she was determined to find the other spring if she were years engaged in the search. She was now certain that we were right, that the secret chamber existed, and that the entrance was there, of neither of which facts had she been quite sure in her own mind before.

Evil Days.
With the cheering thought that she was punished, and that perhaps her fault was thus in some little way atoned for, and with the happy conviction that her husband loved her for her own sake, and not for that of her money, Sophy Gregory recovered from the weight of her sorrow and remorse more quickly than could have been expected; and by the end of another ten days she was able to leave her room, and go for a little walk leaning
