Posted Murders

This is the first Book of a series I'm writting that takes place in Victorian England.

Inspector Stanley is called to investigate the murder of an high society woman. The investigation is already difficult, due to social prejudices from the victim's family, who consider Stanley far bellow them in the social rank. But more difficulties come to the Inspector's way when he starts to receive letters from the Killer. Is he going to be able to stop this man before he kills again?
