Golden Age crime-writing was not the exclusive province of the British and the Americans. Arthur Upfield is an interesting case, because something very disturbing happened to him. Upfield was born in 1890 in Hampshire, but in 1910, after he fared poorly in his exams (he was planning to become an estate agent) his father shipped him off to Australia, where he eventually settled – if you can call it settling, for he led an itinerant life.
