He has from the beginning written both fiction and poetry as well as a wide range of radio, televison and journalism. Vocal music was for many years his avocation. Beginning in his forties, he sang with a number of choirs in Kingston, Montreal and Charlottetown. He appeared as bass soloist in Handel's Messiah, Bach's St Matthew Passion, and Mozart's Requiem. He currently lives in an old house in the village of Eldon in Prince Edward Island. His latest book is entitled Mystery Stories.
