The Secret of the Gorge [antikvár]

A kötet gerince megtört, ragasztása sérült, a könyvtest kettévált. A borító szélei enyhén kopottasak.
Why so many people should want the ugly old sofa, Jenny couldn't imagine. Then Tom suggested they had a good look at it and they found the letter... Somewhere in the gorge, the stolen Whiteflower diamonds were hidden. The Lone Piners had the only clue, but could they discover what it meant before the thieves caught up with them? In this desperate search, the Lone Piners meet some of their most ruthless enemies, and danger piles on danger until the adventure reaches its terrifying climax.
