 Jonk's friend Bill Smith has read of a local legend that describes how a giant Green Man once strode across the countryside from Wiltshire to East Anglia.Believing the legend is the key to understanding Jonk's experience in the woods, Jonk, Bill and their rather sceptical friend Arthur (Arf) Minnett set out to solve the riddle of the Green Man.It soon becomes apparent that the stone-faced man is an ancient warlord who needs the golden buckle to regain his malevolent power.
