Shunned and Dangerous (An Amish Mystery #3) by Laura Bradford

Living in the small town of Heavenly, Pennsylvania, Claire Weatherly has come to admire the Amish for their wholesome, honest way of life. But she also knows that nothing is as simple as it seems—especially when murder disturbs the peace.

Claire has always been game for a good puzzle, so when she hears that Mose Fisher has made one of his famous corn mazes, she can’t wait to walk the paths and test her skill. But she’ll have a much more serious puzzle to solve when, deep inside the maze, she discovers the body of Amish dairy farmer Harley Zook.
