John was born in the mid-fifties in Dagenham, London, on part of the largest council estate ever built, and was the first pupil from his local secondary modern school to attend university. He has now taken early retirement to write, having spent the first part of his life working in education and the public sector. He was the director of a college, a senior school inspector for a local authority, and was head of a unit for young people with physical and mental health needs. When he is not travelling, going to the theatre or the pub, he writes.
John is currently working on a trilogy of novels set in modern day London. These police procedurals examine the darker side of modern life in the East End of the city.
