The Unquiet Heart

Sarah Gilchrist has no intention of marrying her dull fiancé Miles, the man her family hope will restore her reputation and put an end to her dreams of becoming a doctor, but when he is arrested for a murder she is sure he didn't commit she finds herself his reluctant ally. Beneath the genteel façade of upper class Edinburgh lurks blackmail, adultery, poison and madness and Sarah must return to Edinburgh's slums, back alleys and asylums as she discovers the dark past about a family where no one is what they seem, even Miles himself.
