"No, the shadow's too black," replied Jack. "And we can't hear him, either. Wish it was sand! The rollers make such a noise on that shingle, and the tide's too high for any one to walk on the sands."
But he had hardly finished speaking when, looking to the left, he saw a black shade on the shingle, at a point where a mass of rocks at the foot of the cliff interrupted the direct path. It moved a few yards, and again disappeared. That was enough for Jack.
"There he is!" he whispered. "Take care, youngster; we don't want any broken necks."
Quickly lowering himself over the steep side of the cliff until his feet touched the zigzag path, he began to race down as quickly as the need for quietness permitted, Arthur following somewhat less rapidly. At the foot he waited for his cousin, then both set off toward the village, the direction in which they had seen the shadow move.
He almost wished now that he had refused to let Arthur come with him, for while the sound of one person running on the loose shingle might pass unheard, it was not so likely that two could run with the same security. But he did not care to send the boy back now, so they went on together, more slowly than he would have done alone.
De Fronsac must have walked rapidly, for it was not until they had nearly reached the village that they caught another glimpse of him. Then, however, the gap in the cliff brought him well into view, and the boys had no difficulty in following. He kept straight on across the deserted harbor and on to the footpath at the other side running up the cliff,—a short cut for pedestrians leading to the highroad a little short of Gudgeon's farm. Not far up, however, the path forked, a narrow track leading down again to the beach, which it reached about two hundred yards farther east.
Jack had to wait until De Fronsac had disappeared before he followed him across the open space around the harbor, for if he had chanced to turn he must have caught sight of any one behind. Thus, when the boys reached the fork of the path, they were uncertain whether to continue up the cliff, or to turn down to the right.
"Listen!" said Jack.
Holding their breath they waited. Was that a faint sound from above?
"Let us chance it," said Jack, and up they went, following the steep winding path until it brought them once more to the highroad. They glanced up and down; there was nothing to be seen, only Gudgeon's farm about a stone's throw to the right, and the bare white road winding down-hill past it and up-hill to the left. They were again at fault; presumably De Fronsac, to avoid the very loose shingle near the village, had chosen the cliff path, only to turn to the right and continue his road by the beach.
