Book excerpt: Sex, drugs, gambling, ghosts, drinking, rugby - and even some police work. Hong Kong on the edge of empire was teeming with triads, smugglers, Chinese immigrants and Vietnamese refugees. Simon's memoir of his time in the Hong Kong police - from the 1970s until after the handover - is a fast-paced tale. From the murky back streets of Kowloon to the open seas, his shocking and hilarious story shows what life was like on the Hong Kong beat.
