Two of my favorite crime writers hail from Scotland. Ian Rankin lives in Edinburgh and his stories are mostly set there. Denise Mina lives in Glasgow and her stories are often set there. But her latest one, "Blood, Salt, Water," is set in another town entirely, a place called Helensburgh. This community is located in a beautiful spot right on the oceanfront. It was once the playground for millionaires. The mouldering ruins of their Victorian mansions are now rotting high up on the hillsides.
