Edinburgh, 1948. Loud-mouthed nurse Helen Crowther has been in her new job barely a year. She's already made waves - everywhere she goes she dodges looks of disapproval and eyes roll behind her back. Still, she is determined to better the city she loves so dearly. The last thing she needs is another string of murders to distract her . . . But when three gentlemen dressed in rags wind up dead in very public places, she can't help but jump straight in. As Helen resolves to find the killer, she is propelled into a darker world of class, revenge and gruesome death, until suspicion falls on someone very close to home.
