Undetected by Jeffrey Marshall

Suzy Perry, a lovely, accomplished older woman, has married into a new family in Westchester County, NY, after being widowed not long before in Atlanta. Her new husband, Dean Perry, is besotted with her, but his son, Alex, and daughter-in-law Lisa are troubled by how little they know about her. Who is she, and why is she so reticent to share details about her previous life?
Little by little, clues and tidbits of information persuade Alex that he needs to know more. As the questions pile up, Alex, a journalist, elects to hire a private detective to probe Suzy’s past, without informing his father. Over time, it becomes clear that Suzy changed her name when she moved to Atlanta – and that she had been married for many years to a car dealer in Missouri who died suddenly shortly before she left.
Is all this innocent, or something more sinister? Once circumstantial, the evidence becomes more concrete – and then Suzy is on the run.
