Death of a Maid, by M.C. Beaton

Another Hamish Macbeth mystery. You know, I think I only half-read the actual plot, while drooling over the real-estate porn details- the thick stone walls, the storms rolling in over the lochs, the slabs of peat in the fire... Someone killed someone, and Hamish sorted it all out, but the main appeal of these is the houses.
