He set his lips as he tried to balance contending claims, using arguments on both sides that had led him into a maze before; and each time he was forced back upon the decision he had already made. Something must be risked, and in the meanwhile he would follow up his clues alone; it would be time enough to warn the authorities when he had found out what was to be feared.
His face was tense as he turned to Whitney.
"I think we'll have to work out this thing in our own way; but as the tides won't suit for the next few days, we'll take a run north along the Eskdale road."
"Very well, if you think that's somehow in the plot," Whitney agreed. "It's possible you're right about the other matter. You'd put the load on the proper shoulders if you warned your authorities, but if they didn't get to work very quietly, they'd scare the fellows off before they found out much. The trail's certainly not plain, but I guess we can follow it without showing what we're after."
"See if the anchor's holding," said Andrew. "I'm going to lie down."
He lowered his folding cot, but the flood tide had covered the flats, and the yacht was rolling gently on the swell it brought in before he went to sleep.
Farther up the narrowing Firth the wind was faint, and Elsie, lying awake toward high-water, heard the murmur of the sea. It throbbed in a deep monotone through the stillness that brooded over the fog-wrapped countryside. Elsie listened to it for a time, wondering what Andrew was doing as she glanced at the obscurity outside her window, for the Firth was dangerous to navigate in thick weather. He had promised to return the next day, and she wanted him back at Appleyard. She felt safer when Andrew was about. He was not clever, but he was practical, and one could trust him to do the right thing in a difficulty.
Elsie was glad to remember this, because she had difficulties to contend with. Dick had been restless and depressed, and his occasional efforts at rather boisterous gaiety had emphasized his general moodiness. He was obviously not well; but Elsie thought this did not account for everything. Then her mother had been quieter than usual, and her manner seemed to indicate secret anxiety.
Elsie felt that things were going very wrong at Appleyard. Something mysterious and sinister threatened the household, but she could not combat the danger, because she did not know what it was. Even now, when every one was probably asleep, she had an instinctive feeling that there was mischief on foot. She told herself that she was highly strung and imaginative, but her uneasiness would not be banished. Anyway, she could not sleep. Seeing that the fire had not quite gone out, she got up, finally, and, putting on her slippers and kimono, lighted a small reading lamp. She drew a thick curtain across the window, and then opened a book; but she found that her thoughts would dwell on Andrew, somewhere out in the fog.
