"I haven't the least idea, Tom; but at any rate, I will consult your father. It is something to learn as much as we have, and we certainly seem to have got on the right clue. I never quite despaired, but I feel now pretty certain that we shall get to the bottom of it at last."
"It will do Percy Johnstone a world of good to take down his conceit a bit—a stuck-up monkey!"
"Don't say that, Tom. I felt it myself so much that I am sure I could not wish my worst enemy to go through such a thing."
"I don't wish Percy Johnstone any particular ill, Roland; but if somebody has got to suffer, I would rather it was him than anyone else in Brownsville. The insufferable airs that fellow gives himself are disgusting."
Mr. Fernlea was greatly interested when he heard the news. "I have no doubt whatever that you are on the right track now, Roland. Taking your father's letter, the points we noticed when we read it, and the facts we know now, that Johnstone is a heavy and unsuccessful speculator, seem to show without doubt that he is the real thief. His conduct in not arresting your father at once, and in allowing him without pursuit to get across the frontier, is accounted for now. He did not want anything like a public trial, for in that case the numbers of the missing bonds must have been made public, and might in that way have been traced to him. I have no doubt whatever that he is the thief. But the question is, how are we to prove it?
"Of course if Johnstone goes on at this game and it continues to be unnoticed, there will be a smash up sooner or later; but even then the whole thing might not come out. If your father should come back here, they would be obliged to arrest him. But even if he denounced Johnstone as the real thief, we have nothing to go upon. The mere fact that he has speculated would in itself be no proof, or that he did so under an assumed name, for he would urge that many people do the same, and that he only adopted this precaution because, being in the position of president of the bank, he did not wish people here to know that he dabbled in shares. I own that I do not see what our next step is to be. It seems to me that we must wait and watch."
"That is what I was thinking, sir. Will you kindly give me leave to be away from your office till this is done? I should like to come here of a morning and go in and out as if I was in your employment, in case Mr. Johnstone was watching me, which is not likely. He would then suppose that I am still working for you, but went out rather frequently on errands."
"Certainly, Roland, and if you want any money let me know. Anything that you may require to carry the matter through I shall be glad to let you have."
"Thank you, sir! but I hope I shall not be obliged to avail myself of your kind offer. My mother still has the proceeds of the sale of our furniture, and I need hardly say how glad she will be to spend it if she knows that there is a chance of proving my father's innocence."
Roland now kept a strict watch upon Mr. Johnstone's movements, and the next time that gentleman boarded the train at Brownsville, Roland did the same, but got into a third-class compartment forward. He was close at hand, however, when the banker presently took out his ticket, which was only for a town some thirty miles out; but when the train stopped at this station the banker ran into the office, and, procuring a ticket for Chicago, continued his journey to that city. When he alighted there Roland followed him. He went to a small house in a retired quarter, and on knocking at the door was admitted without question, and Roland concluded that he habitually stayed there. He came out in a few minutes without the bag which he had carried in, and as soon as he was fairly away Roland, seeing that there was a notice in the window that there was an apartment to let, knocked at the door.
