When Isabel Lambert opens the door to a son her husband, Sam, knew nothing about, she takes the product of his affair during the Korean War better than he does. After Izzy insists Sam see his 40-year-old son, Mark Taylor, Sam goes off to a friend's cabin to think things through. Can a marriage of more than 40 years survive when one spouse finds out the other cheated years earlier? Told through a journal that Izzy's daughters have asked her to write, Laura Abbot's Stranger at the Door (3) is well written but moves slowly.
