London, 1883. The brutal murder of Rose Parmiter seems, at first glance, to be a random and senseless act. Rose was the beloved cook at Evergreen House, a place of refuge for women and children, a place from which they can start their lives afresh. Proprietor Rebecca Harris is profoundly shocked by the death of her dear friend and alarmed at the mysterious events which begin to unfold shortly afterwards. Could the past be casting a shadow on the present? The malign legacy of the Everley family who called Evergreen home, cannot be ignored. After two further deaths it becomes clear there is an evil presence infecting their sanctuary, and Rebecca must draw out the poison of the past so the Evergreen residents can finally make peace with the darkness in their lives.
