Edinburgh, 1948. Helen Crowther leaves a crowded tenement for her own office in a doctor’s surgery. Words of disapproval come at her from everywhere but she’s determined to take her chance. She’s barely begun when she stumbles over a murder and learns that no one will fight for justice at the risk of a scandal. As Helen resolves to find a killer, she’s propelled into a darker world than she knew existed, hardscrabble as her own can be. Disapproval is the least of her worries now.
