Death of a Chimney Sweep by M.C. Beaton
In the south of Scotland, residents get their chimneys vacuum-cleaned. But in the isolated villages in the very north of Scotland, the villagers rely on the services of the itinerant sweep, Pete Ray, and his old-fashioned brushes. Pete is always able to find work in the Scottish highlands, until one day when Police Constable Hamish Macbeth notices blood dripping onto the floor of a villager's fireplace, and a dead body stuffed inside the chimney. The entire town of Lochdubh is certain Pete is the culprit, but Hamish doesn't believe that the affable chimney sweep is capable of committing murder. Then Pete's body is found on the Scottish moors, and the mystery deepens. Once again, it's up to Hamish to discover who's responsible for the dirty deed--and this time, the murderer may be closer than he realizes.
This is the 27th in the Hamish Macbeth series. I have not read any of them and unfortunately I have not been able to fit this in yet but I look forward to reading it in the near future and will give a full review when I do.
