Buttons and Bones (Needlecraft Mystery Series #14)

Owner of the Crewel World needlework shop and part-time sleuth Betsy Devonshire heads for the Minnesota north woods to renovate an old cabin. But beneath the awful linoleum is something even uglier- the skeleton of a Nazi. Betsy's investigation yields the site of a former German POW camp, a mysterious crocheted rug, and an intricately designed pattern of clues to a decades-old crime.
