50-year-old governess Mary Wilcox has dealt with more than her fair share of rich families, and she does so with patience and grace.

But she's not used to dealing with murder.

When Mary moves into the grand Ashford estate to assume her role as a governess to three children, she is met with the polite formality of the estate's matriarch and the curiosity of three children.

Little does she know she is stepping foot into a nest of secrets and lies.

As Mary becomes more involved with the family, she begins to suspect foul play in the recent death of the family's patriarch. Even as she battles her own past demons and struggles to separate past from present, she is forced to wonder—which of the family members should she be protecting?

And who should she be afraid of?
