The most wonderful thing of all had been the finding of the shabby old trunk in the attic whose contents of rare old coins and postage stamps had brought Billie in nearly five thousand dollars in cash. The money had enabled Billie to replace a statue which she had accidentally broken a little while before and had also given her the chance to go to Three Towers Hall, a good boarding school, and Chet the opportunity to go to the Boxton Military Academy, which was only a little over a mile from Three Towers Hall. The good times the girls had at school—and some bad times, too—have been told of in the second book of the series, called, “Billie Bradley at Three Towers Hall.” In North Bend, where the girls had always lived, there lived also two other girls, Amanda Peabody and Eliza Dilks. These girls were sneaks and tattletales of the worst order and were thoroughly disliked by all the girls and boys with whom they had come in contact. When the chums had heard that Amanda was to accompany them to Three Towers they were absolutely dismayed, for they expected that she would spoil all the fun. Amanda had done her best to live up to the expectations of the girls, but try as she would, she had not been able to spoil entirely the fun. And this very failure had, of course, made her and her chum, Eliza Dilks, furious. Both Three Towers Hall and Boxton Military Academy had been built on the banks of the beautiful Lake Molata, and the girls and boys had spent many happy hours rowing upon the lake in the fall and skating upon it in the winter. But the most amazing thing that had happened to them at Three Towers had been the capture of the man the girls called “The Codfish.” This rascal had attempted to steal Billie’s precious trunk in the beginning, but Billie and the boys had given chase in an automobile and had succeeded in recovering the trunk. They had also succeeded in getting a good look at the man, whose hair was red, eyes little and close together, mouth wide and loose-lipped. It was this last feature that had given the thief his name with the boys and girls. For the mouth certainly resembled that of a codfish. Later the “Codfish” had turned up again near Three Towers Hall, had robbed one of the teachers of her purse when she was returning from town, and had later succeeded in making off with a great many valuables from Boxton Military Academy.
