"A missing letter is the key to the where-abouts of Fort Freedom, the stockade that disappeared after the Revolutionary War. The fort is located somewhere within the boundaries of Shoreham and has been sought after for many years, not only for its historic value, but for the gold supposed to be hidden there by the early settlers. ...Wherever there is a mystery the Happy Hollisters are sure to be in the thick of it."
This is the description on the dust jacket of this 1955 edition of another in the Happy Hollister series. This book has its owners name written in ink on the frontspiece. The dust jacket is clean and untorn. The pictures are partial page in turquoise ink.
