Have now spent 2 days ..... have got all clues except the last one - have the letters KCBOAAD but am blowed if I can find a melancholy hamlet. Do I need an Ordnance Survey map?? This is driving me nuts! Any assistance appreciated - maybe one of my letters is wrong.
The answer to the last clue is CreDiton so you have the wrong answers to the clues that gave you the D and one of the As. The second village is ChaGford and the aeronautical engineer is Frank WhiitLe giving the letters: K C B O A G L and D. Head north from Crediton and you should find the hamlet.
