"I dare not stop on my journey till I can feel that I am lost in the great world of London. Don't look at me so sadly! I shall never forget my promise; I shall never forget to write. I have friends—not friends like you, but still friends—to whom I can go. I can feel safe from discovery nowhere but in London. My danger is great—it is, it is, indeed! I know, from what I have seen at Porthgenna, that Mrs. Frankland has an interest already in finding me out; and I am certain that this interest will be increased tenfold when she hears (as she is sure to hear) of what happened yesterday in the house. If they should trace you to Truro, oh, be careful, uncle! be careful how you deal with them; be careful how you answer their questions!"
"I will answer nothing, my child. But tell me—for I want to know all the little chances that there are of your coming back—tell me, if Mrs. Frankland finds the letter, what shall you do then?"
At that question, Sarah's hand, which had been resting languidly on her uncle's arm while they walked together, closed on it suddenly. "Even if Mrs. Frankland gets into the Myrtle Room," she said, stopping and looking affrightedly about her while she replied, "she may not find the letter. It is folded up so small; it is hidden in such an unlikely place."
"But if she does find it?"
"If she does, there will be more reason than ever for my being miles and miles away."
As she gave that answer, she raised both her hands to her heart, and pressed them firmly over it. A slight distortion passed rapidly across her features; her eyes closed; her face flushed all over—then turned paler again than ever. She drew out her pocket-handkerchief, and passed it several times over her face, on which the perspiration had gathered thickly. The old man, who had looked behind him when his niece stopped, under the impression that she had just seen somebody following them, observed this latter action, and asked if she felt too hot. She shook her head, and took his arm again to go on, breathing, as he fancied, with some difficulty. He proposed that they should sit down by the road-side and rest a little; but she only answered, "Not yet." So they went on for another half-hour; then turned to look behind them again, and, still seeing nobody, sat down for a little while to rest on a bank by the way-side.
After stopping twice more at convenient resting-places, they reached the end of the cross-road. On the highway to which it led them they were overtaken by a man driving an empty cart, who offered to give them a lift as far as the next town. They accepted the proposal gratefully; and, arriving at the town, after a drive of half an hour, were set down at the door of the principal inn. Finding on inquiry at this place that they were too late for the coach, they took a private conveyance, which brought them to Truro late in the afternoon. Throughout the whole of the journey, from the time when they left the post-town of Porthgenna to the time when they stopped, by Sarah's desire, at the coach-office in Truro, they had seen nothing to excite the smallest suspicion that their movements were being observed. None of the people whom they saw in the inhabited places, or whom they passed on the road, appeared to take more than the most casual notice of them.
It was five o'clock when they entered the office at Truro to ask about conveyances running in the direction of Exeter. They were informed that a coach would start in an hour's time, and that another coach would pass through Truro at eight o'clock the next morning.
"You will not go to-night?" pleaded Uncle Joseph. "You will wait, my child, and rest with me till to-morrow?"
"I had better go, uncle, while I have some little resolution left," was the sad answer.
