As has been previously told, Ruth had come to the banks of the Lumano
River and to her Uncle Jabez Potter's Red Mill some years before, when she
was a small girl. She was an orphan, and the crabbed and miserly miller
was her single living relative.

The first volume of the series, entitled "Ruth Fielding of the Red Mill,"
tells of the incidents which follow Ruth's coming to reside with her
uncle, and with Aunt Alvirah Boggs, who was "everybody's aunt" but
nobody's relative.

The first and closest friends of her own age that Ruth made in her new
home were Helen and Tom Cameron, twin children of a wealthy merchant
whose all-year home was not far from the Red Mill. With Helen and Mercy
Curtis, a lame girl, Ruth is sent to Briarwood Hall, a delightfully
situated boarding school at some distance from the girls' homes, and
there, in the second volume of the series, Ruth is introduced to new
scenes, some new friends and a few enemies; but altogether has a
delightful time.

Ensuing volumes tell of Ruth and her chums' adventures at Snow Camp; at
Lighthouse Point; on Silver Ranch, in Montana; on Cliff Island, where
occur a number of remarkable winter incidents; at Sunset Farm during the
previous summer; and finally, in the eighth volume, the one immediately
preceding this present story, Ruth achieves something that she has long,
long desired.

This last volume, called "Ruth Fielding and the Gypsies; Or, The Missing
Pearl Necklace," tells of an automobile trip which Ruth and her present
companions, Helen and Tom Cameron, took through the hills some distance
