Talk:The Slipper Point Mystery (novella)/Chapter 8

Two girls, Doris Craig and Sally Carter, who have met and become acquainted on the shore of the little Manitvick River and share the secret of a mysterious cave on the banks, have discovered that an underground passage leads from it into the cellar of Miss Camilla Roundtree. She has never before known of its existence, but guesses that it may have been constructed many years before by her father, an ardent abolitionist, to assist the flight of runaway slaves. Of the mysteriously inscribed scrap of paper concealed in the cave she can make nothing till Doris hits on the explanation that it is a secret code. This leads to Miss Roundtree's deciphering a letter left long ago among her father's effects, and from it they learn the fate of Miss Camilla's long-lost brother and clear away the supposed stain that has rested on her family history for many years. From it they also guess that some porcelains and other valuables may be concealed in the tunnel.
