Don't let anyone in. Don't let anyone out. One of us is a murderer. Scotland, 1930s. The family estate of Loch Down has been home to the Inverkillen clan, mired in quarrels and grievances, for more than 600 years. The family's fortunes have diminished significantly over the centuries, and they are forced to engage in un-aristocratic activities: selling salmon and making crap whiskey. But nothing comes of it, and to top it all off, the body of the 19th Earl is found in the river with a broken head. The investigation is entrusted to the hapless Inspector Jarvis, who quickly writes off the incident as an accident. After all, there are no crimes in small towns, only fights in pubs. The only one who disagrees with this conclusion is the observant housekeeper Mrs. McBain. She knows many more secrets of the noble family than anyone else. She is sure that there has been a murder, and the killer is hiding in the house in plain sight. Beth Cowan-Erskine, like no one else, knows what she is writing about, because through her husband she became related to an ancient Scottish clan, which served as the source of inspiration for this book "An entertaining story and a fascinating dive into the strange and wonderful customs of the British aristocracy." – C.J. Bennett, bestselling author of The Windsor Knot
