What secret selves lie within us? And of what dark deeds are they capable? Inspired by the notorious case of Lord Lucan, Flynn Berry‘s A Double Life (Viking, $26) follows Claire decades after her father murdered her nanny, and left her mother nearly dead, before disappearing. Claire has convinced herself that she has moved beyond the events of her childhood, capable of living a healthy, functional life, only to be derailed each time a new sighting of her father is reported. But this time, waiting for confirmation of a false sighting, Claire finds that she cannot wait any longer and might be more like her father than she thought. Berry explores class, ethics, and the psychology of violence to understand the ways in which we are shaped by trauma; this is a mystery that delves beneath the surface to look at the unsavory things that dwell there, both in others and in ourselves.
