This fast-moving story takes the reader rapidly along dark paths of sinister events in Le Sentier, the heart of Paris's rag trade. One spring morning a Thai girl is found dead in a fashion workshop. Another unlucky prostitute, or something more sinister? A club is uncovered where people secretly get filmed having sex - including some very distinguished men. This is the seedy underworld of Paris - the traffic in heroin, illegal immigrants without work permits, police officers' secret lives. A Turkish man - a police informer and leader of exploited immigrants rag-trader workers - is also Police Inspector Danquin's lover. This is a gripping morality tale of twentieth-century Paris.
