At the Water's Edge by Sara Gruen. "A woman and her disgraced high-society husband leave the US, along with his best friend, during WWII to search for the Loch Ness monster. The trio is ill-equipped to deal with the deprivations of wartime Scotland. The woman ends up befriending the house maids and falling in love with the inn-keeper, while her husband and his friend make fools of themselves and enemies of those around them."
