The townspeople whispered about old Miss Westover, the spinster whose father in his will had mentioned personal property left to her. But no personal property ever turned up for the kindly, indigent, spinster. Judy Day and her twin brother Jon became involved in the recluse's life when a pet snake escaped onto Miss Westover's grounds. There Judy found an old locket which Miss Westover had treasured because it had been given her by a suitor whom her father had not approved. Grateful for the locket's return she rewarded Judy with an heirloom box which contained four letters concealed in a hidden compartment. Discovery of the letters reunited the lonely old lady with her long-lost lover and uncovered a hidden room in the old tower where securities secreted by her father made her wealthy. All terribly improbable but highly readable, this uses the tried-and-true combination of do-gooding, lost loves, hidden-treasure and secret rooms which girls can't get enough of. Nancy Drewish, but a little younger.
