Jamie Forest, transplanted New Yorker, is enjoying her first spring in the Northwoods of Minnesota when her octogenarian friend Clarence introduces her to an elderly recluse, Nella Fox. Nella wants help writing her memoirs. She is the owner of an estate that was once a TB sanatorium. The hospital is long abandoned and crumbling. Rumors abound that the neglected building carries the secret of a long-ago murder. When one of the cousins who cares for Nella is found dead in the old hospital, Jamie is drawn into its dark history. Instead of enjoying the spring awakening, Jamie finds herself piecing together the story of the estate and trying to solve two mysteries-one in the past and one in the present.
