Climbing the rocks upon which the castle stands, he made a careful survey of its outside and finally gained access to the interior, much disappointed to find nothing at all remarkable, though St. Aubin's castle is not wholly a ruin and was once rented and occupied for a season by an eccentric Englishman.
Nothing was now visible save swirling fog and for the first time, Roger realized what that fog meant. He hastily made his way to the little beach, where the tide, still out, would permit him to cross to the mainland. To start in the right direction was simple enough, for he very well knew which side of the castle faced the shore, but he had taken scarcely twenty steps down the sand when he saw that he had no certainty of keeping his bearings once the island was left behind.
Roger was only twelve, but he was possessed of common-sense and self-reliance. Though the youngest of the family he had been so thoroughly impressed with the necessity of considering "safety first" in regard to Win, that in an emergency of any kind he was usually level-headed. He stopped where he was, searching his pockets for the compass Captain Thayne had given to each of his three children.
Roger's pockets yielded a strange and varied assortment of objects, presumably of value, but no compass. He looked irresolutely behind where the castle was just visible as a darker spot in the fog. Nothing at all could be distinguished ahead.
From the lighthouse on the point came the tolling of a bell, but its warning tones were so scattered and disguised by the fog, that its sound was of no use as a guide.
For several moments Roger stood where he was. The distance to shore was not great if he was only certain of going straight ahead. To swerve from that direction meant wandering out to meet the cruel Jersey tide, presently coming in like a hunter on its prey. To remain where he was meant anxious hours for his mother and for Win, about whom Roger was already so much concerned.
Having weighed the alternatives, he took five steps forward and stood absolutely surrounded by the whirling mist. A sort of horror came over him, a keen realization of his helplessness before one of the great elemental forces of nature. The risk was too great! There was a chance that he might keep in the right direction with nothing to guide him, but it was only a chance. Worried as his mother would doubtless be, better that she endure a few hours of anxiety than lasting grief.
Turning squarely about, Roger retraced his footsteps, already faint, to the castle, where he perched forlornly on a high rock. A little later, he heard for he could not see, the low hiss and gurgle of the coming tide. Roger was a big, strong, brave boy, but at the sound, he could not suppress a few tears, and they were not wholly for his own plight.
Mrs. Thayne returned from her fruitless expedition to the beach, looking still more distressed.
"I can't imagine where Roger is," she said anxiously to Frances. "Of course, there may be some good excuse for this performance, but I don't see what it can be. He knows that he is not to go into town without permission and it seems as though he would have come home for luncheon unless he was in St. Helier's. If he really has been disobedient and played truant again into the bargain, I shall ask Mr. Fisher to punish him."
