Hook, Line, and Murder

What does Meg, a retired kindergarten teacher, do when the killer of her husband and only child still walks free a year after dirt had covered their graves? Go rogue, of course! When the detective responsible for Meg's nightmares takes over the murder investigation of her former student, Meg hunts the killer down with help from her friends. Their cozy lunches at Sweet Buns Café turn into tactical meetings while these retired grade school teachers get themselves in trouble better suited to those in their twenties. And to put the icing on their cream scones, someone is after Meg. Is it the killer? Or has Meg uncovered secrets better left buried with her loved ones?
