ck all alone.

Eline, who was rather daring in spite of her timid manner, made a
half-suggestion that the girls go out in autos to see what happened
at Shark's Tooth, but Mrs. Chester, exercising her authority, vetoed the
scheme.

Mr. Haley started off alone, and was followed later by the boys, who
arranged to conceal themselves where they could have a view of the ledge
of rock that was uncovered at low water.

There was a half-moon that night and by the light of it Jack and his chums
could see the long, black ledge extending out into the bay. They had a
glimpse of Mr. Haley walking slowly up and down the beach, now and then
looking at his watch to note the time. Jack and the others did likewise.

"It's nine now," whispered Walter, after a long--a seemingly long--wait,
though it was really only a few minutes.

"And nothing seems to be happening," remarked Jack.

"Look!" suddenly exclaimed Ed, pointing to the sandy stretch. A dark

"No, no, Jim dear! Don't call anyone!" interrupted Mrs. Raymond. "I dare
not be seen. You don't know the stigma I am under. I even hesitated to
come and see you in this secret way, but I am in need of help. It was the
only way I could think of. I am so--so afraid of arrest."

"Well, you needn't be!" cried her brother. "We can prove your innocence!"

"Prove my innocence! How? Only Nancy Ford can do that, and she can't be
found, I have been searching for her so long--so long!" Her sobs prevented
her from talking.

"But Nancy Ford is found!" cried the keeper of the light, "and the boys
