Wynifred Mallory was delighted to learn that the Go-Ahead Club would be allowed to camp at Lake Honotonka. Soon they set off, with their boy friends to keep them company in another camp not far away. Those boys played numerous tricks on the girls, and the girls retaliated, you may be sure. And then Wyn did a strange girl a favor, and learned how some ancient statues of rare value had been lost in the lake, and how the girl's father was accused of stealing them.
The death of the Count de Chalusse, the theft of his will and two million francs, the false accusation of Marguerite de Chalusse, make up a mystery which is solved only after some extraordinary adventures. Followed by Baron Trigault's Vengeance.
