Murder at Harrogate

At the Wetherby Hydro, everyone has decided who the murderer meant to kill. That certainty may be the most dangerous clue of all.
Ruth Calder has been receiving threats: notes beneath her door, a room entered without permission, a page gone missing. When another guest, Eudora Vardon, dies during an electrical treatment, the hotel's story seems obvious. The wrong woman was killed.
Julian Ashcombe is not convinced. Clara Bennett takes charge of Ruth's harassment enquiry, following a trail of concealed papers, old grievances and hotel secrets through Harrogate's polished spa world. Yet the more clearly the threats point towards Ruth, the less certain Clara becomes that they explain the murder.
Three people have reasons to hide the past. One knows the treatment rooms—and the records—better than anyone. To uncover what happened, Julian and Clara must ask not only who was threatened, but who benefits when a murder is mistaken for a substitution.
Behind the Hydro's gracious doors, every kindness may conceal a calculation. And the person most eager to explain the evidence may be the one who arranged it.
