Terrified at the sudden seriousness of the man's voice, she managed to gasp out, however, that, after her usual habit, she had not opened the official letters, but had sent them to her more experienced colleague for advice and information; that she never could understand them herself,--they made her head ache, and interfered with her other duties,--but HE understood them, and sent her word what to do. Remembering also his usual style of indorsement, she grew red again. “And what did he say?” “Nothing; he didn't return them.” “Naturally,” said Mr. Home, with a peculiar expression. After a few moments' silent stroking of his beard, he suddenly faced the frightened woman. “You oblige me, Mrs. Baker, to speak more frankly to you than I had intended. You have--unwittingly, I believe--given information to a man whom the Government suspects of peculation. You have, without knowing it, warned the postmaster at Hickory Hill that he is suspected; and, as you might have frustrated our plans for tracing a series of embezzlements to their proper source, you will see that you might have also done great wrong to yourself as his only neighbor and the next responsible person. In plain words, we have traced the disappearance of money letters to a point when it lies between these two offices. Now, I have not the least hesitation in telling you that we do not suspect Laurel Run, and never have suspected it. Even the result of your thoughtless act, although it warned him, confirms our suspicion of his guilt. As to the warning, it has failed, or he has grown reckless, for another letter has been missed since. To-night, however, will settle all doubt in the matter. When I open that bag in this office to-night, and do not find a certain decoy letter in it, which was last checked at Heavy Tree Crossing, I shall know that it remains in Green's possession at Hickory Hill.” She was sitting back in her chair, white and breathless. He glanced at her kindly, and then took up his hat. “Come, Mrs. Baker, don't let this worry you. As I told you at first, YOU have nothing to fear. Even your thoughtlessness and ignorance of rules have contributed to show your own innocence. Nobody will ever be the wiser for this; we do not advertise our affairs in the Department. Not a soul but yourself knows the real cause of my visit here. I will leave you here alone for a while, so as to divert any suspicion. You will come, as usual, this evening, and be seen by your friends; I will only be here when the bag arrives, to open it. Good-by, Mrs. Baker; it's a nasty bit of business, but it's all in the day's work. I've seen worse, and, thank God, you're out of it.” She heard his footsteps retreat into the outer office and die out of the platform; the jingle of his spurs, and the hollow beat of his horse's hoofs that seemed to find a dull echo in her own heart, and she was alone.
