Hong Kong in 1970 was the fastest expanding city in the world, a city that lived on three levels - the expatriates, nearly always British who lived in almost complete isolation; the vast mass of Chinese residents struggling to get by and improve their lot; and finally the criminal and corrupt underside which not only fought among itself but also affected the life of everyone else in the Crown Colony through fear and corruption. Fighting to hold this in check - and by and large succeeding - were the Hong Kong police force. At the officer level, many were British. Into this heady and dangerous mix steps a young Merseyside policeman, Chris Emmett. His account of those times brings vividly to life the crime, prostitution, drugs, triad street gangs and corruption that was an important part of the fabric of Hong Kong of those days.
