From the introduction: This is a daredevils style adventure of good chaps against dastardly villains. Think Biggles and Bulldog Drummond, though the ending owes a little more to 'Where Eagles Dare'. Play the stereotypes with good heart and enjoy foiling the bad guy's evil plot. The heroes are Roger Blenkinsop and his trusty friends. On a lovely summery morning in 1937, they discover that the Professor has been kidnapped from his home in the village of Melton St Boltoph. What is the secret that the Professor has been working on ? And who were the men with German accents who were seen on the village green that morning ? The answers will take the players to the mountains of Bavaria in their quest to rescue the Professor.
