This is a novel of mystery and adventure in the Scottish Highlands by a fine writer of mysteries for children in the 9-to-12 age range. Cover illustration and frontispiece map appear to be by famed book illustrator Richard Powers. No later printings noted on copyright page, indicating, for this publisher, a first edition. Some cover corner wear, modest edge and spine end wear, some light writing on the upper page edges; pretty tight binding; toning and one corner crease on pages. The jacket has moderate edge wear, shallow chipping on spine ends and some light writing on the front cover. Still, this hardback first is scarce in any condition, especially with the dust jacket.
