Wandering the streets of Brooklyn in his pajamas is not the way Drummond Clark intended to spend Christmas Eve, but sometimes he gets confused. When his son Charlie returns him home, the house explodes! Soon the two find themselves pursued by assassins on an adrenaline-fueled cross-country adventure, and Drummond displays survival skills not many other retired appliance salesmen can boast. Could it be that Charlie’s workaday dad was once a spy for the CIA? A former agent struggling with early-onset Alzheimer’s is a potential disaster, and both sides want him quiet. With short, action-packed chapters and tongue-in-cheek humor, Once a Spy by Keith Thomson is a popcorn movie in book form.
