Ally McKinley might be the owner of the cosiest little guesthouse in the Scottish Highlands, but she also has a reputation as an amateur detective! So when a threatening note drops through her elderly neighbour Juliet Munro’s door, Ally is called in to investigate. But what first seems like a nasty prank soon proves lethal, when the very next day, Juliet is found murdered…

Her faithful dog Flora by her side, Ally soon learns that more than one woman in Locharran has received a poison pen letter. And though locals’ lips are sealed over coffee and cake, Ally skilfully unlocks the old Locharran mystery that connects the recipients: they were all rumoured to be involved in the death of a young woman called Marie McKay. Is someone trying to stamp out Marie’s killer? And if so, who in Locharran is not who they seem?

A faded photo of a little blond boy with pale eyes has Ally on the right track, but when a woman’s scream shatters the village’s gentle calm, can Ally sort through the secrets before the post delivers another murder?
