“John is a quiet spoken, affable man, thoughtful and rational; a surface demeanour, however, that masks a passionate core of molten steel and a determination to do the right thing in the right way. One example of this out of many I could chose from, hinted at by him here, was at a time of dangerous tensions with volatile communities in London... John steered paths between successfully meeting the expectations of a divided diverse society, vocal activists and difficult politicians in mountainous political seas...How he achieved that is revealed in his stories of other kinds of mountains and mountainous seas. No wonder he was a great police officer in the most diverse, problem-riddled, capital city on earth.”
