Her discovery helps to solve a 50-year-old mystery but it also precipitates a murder. As she tries to make sense of the killing, Edna realizes more than one person is hiding behind a false identity. Matching wits with extortionists, arsonists, and frauds, she must determine who is friend and who is foe before another person dies." --
