Edinburgh, 1948. Helen Crowther leaves a crowded tenement home for her very own office in a doctor's surgery. Upstart, ungrateful, out of your depth - the words of disapproval come at her from everywhere but she's determined to take her chance and play her part. She's barely begun when she stumbles over a murder and learns that, in this most respectable of cities, no one will fight for justice at the risk of 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.
