Dopple-Banger is an adult book with some dark adult themes.A murder mystery should be about the entertainment and satisfaction of being drawn away from the tedium of the day and pulled into a world of fiction and fantasy.Put preconceived ideas aside and observe the detail and clues. The past was not so innocent. Those golden years contained many perverse individuals with darker sides they attempted to conceal.There was a time when women like those inmates of the houses of ill-repute should have known their place. There were some women like Big Kate who had no family, little education and they were compelled to participate in dangerous games by the times and manipulated by lascivious scoundrels with voracious appetites for corruption.Sometimes there is a price to be paid for such bad behaviour.Dopple-Banger is a lewd, but extensive detail of retribution for those who think they are beyond justice
