Nora is stunned to wake up one morning and discover that her husband, Brendan, has committed suicide in their home.  Brendan was a police officer in their small town of Wedeskyull, which is also where he grew up. Not only can Nora not believe that Brendan took his own life, she then uncovers that he drugged her the night he killed himself, using a prescription he filled a week before he died. Wondering what Brendan was keeping from her, Nora decides to delve into events from his past, especially his younger brother's death when they were children.  It also appears that there are people in Wedeskyull who want Nora to stop asking questions...  What do they have to hide?
