How old was Morgan in the Spook's Secret? Also, how old was he when he became the Spook's apprentice (and when he left his tutelage)?
Morgan would have been in the final year of his apprenticeship (which would have started when he was thirteen) when the Spook terminated it. He would have been about eighteen. Then eighteen years later he visited the Spook’s house in Chipenden to deliver a letter. Despite the fact that he had specks of grey in his beard that makes him about thirty-six in ‘The Spook’s Secret’.
