Mr. Tallboys looked surprised.
"I do not quite understand, Mrs. Conway, how you can take it in hand."
"No? Well, I can tell you, Mr. Tallboys, that I am going to do so. I am not going to sit down quietly and see my son robbed of his inheritance. I have quite made up my mind to devote my life to this matter, and I have come, not to ask your advice—for I dare say you would try to dissuade me, and my resolution is unalterable—but to ask you to give me what aid you can in the matter."
"I shall be glad to give you aid in any way, Mrs. Conway, if you will point out to me the direction in which my assistance can be of use. I suppose you have formed some sort of plan, for I own that I can see no direction whatever in which you can set about the matter."
"My intention is, Mr. Tallboys, to search for this hiding-place myself."
Mr. Tallboys raised his eyebrows in surprise.
"To search yourself, Mrs. Conway! But how do you propose to gain admittance to the Hall, and how, even supposing that you gain admittance, do you propose to do more than we have done, or even so much; because any fresh disturbance of the fabric of the house would be out of the question?"
"That I quite admit. Still we know there is the hiding-place, and it is morally certain that that hiding-place is opened or approached by the touching of some secret spring. It is not by pulling down wainscoting or by pulling up floors, or by force used in any way, that it is to be found. Mr. Penfold, it would seem, used it habitually as a depository for papers of value. He certainly, therefore, had not to break down or to pull up anything. He opened it as he would open any other cabinet or cupboard, by means of a key or by touching a spring. You agree with me so far, Mr. Tallboys?"
"Certainly, Mrs. Conway. There can be no doubt in my mind that this hiding-place, whether a chamber or a small closet, is opened in the way you speak of."
"Very well then; all that has to be looked for is a spring. No force is requisite; all that is to be done is to find the spring."
