With a coloured frontispiece and four other illustrations by Stanley L. Wood. Undated. An adventure story for boys. The frontier in question is the North West Frontier of India. Condition: The red, cloth covered boards show differential fading, and the spine is rubbed and frayed. The boards are rather bumped. External page edges soiled, and in some places this extends into the book. A reading copy rather than one to buy as a gift.
