The Winter Ground by Catriona McPherson, 295 pages

I've become a fan of the Dandy Gilver mysteries. They're set in Scotland after WWII and feature a aristocratic (low level) wife who is willing to go back to her pre-war responsibilities only. After becoming involved in a mystery featuring missing jewels, Dandy is making a name for herself as a woman who investigates discreetly. This newest mystery features a invalid wife, a winter-camped circus, and a girl who might be a member of Russian royalty in hiding. All in all, just another normal mystery to solve.
