There! It was extended to the utmost and still came a good two feet short of the imperiled girl.

“Vi, hold my feet!” commanded Laura. “Hold me so I can’t go over myself. I’m going to try once more.”

With Vi clinging to her feet, Laura wriggled further over the edge of the cliff. Having progressed as far as she could and being herself in imminent danger of losing her balance and plunging head downward upon those sharp-pointed rocks, Laura clung there, stretching her muscles until they ached, striving to bring the stick within the grasp of Billie’s groping fingers.

The stick would not reach. Billie still hung there, at the mercy of the stout material in her dress, which might give way at any moment. What were they to do?

While the girls are striving desperately to find an answer to this question, a moment will be taken to introduce Billie Bradley and her chums to those who have not already made their acquaintance.

The three girls had been chums since those good old days when Billie Bradley had inherited the queer old house at Cherry Corners, as related in the first volume of this series, entitled, “Billie Bradley and Her Inheritance.” In the attic of the queer old house Billie and her chums had discovered a small fortune in rare old postage stamps and coins.

This lucky discovery later proved the open sesame to Three Towers Hall, the boarding school toward which Billie had long turned yearning, but none-too-hopeful, eyes.

Life at Three Towers had exceeded even Billie’s happy expectations. To be sure, there had been a few heartaches, a few defeats, but these were more than offset by the many victories, the many friends that Billie won for herself in her new environment. Laura Jordon and Violet Farrington, long friends and admirers of Billie Bradley, found their friendship cemented into a firm bond by the mutually shared experiences at Three Towers Hall.

Later, Billie and her chums spent an exciting and decidedly worthwhile summer at Lighthouse Island as the guests of Connie Danvers, whose father owned a summer bungalow there.

Back at Three Towers Hall again, the girls found themselves in the midst of a mystery, the solution of which brought undreamed-of happiness to a widow and her three children.
