Pulitzer winner Gail Caldwell wrote an autobiography of her friendship with fellow writer Caroline Knapp who died young. Their acquaintance was through their pet dogs, a samoyed and german shepherd. Caroline Knapp had previously published Drinking: A Love Story before they met. Gail, also a recovering alcoholic, had not yet met Caroline when she read Drinking: a Love Story while spending a week in Cape Cod alone with her dog. Gail grew up in Texas and Caroline’s childhood was in intellectual Cambridge in the Boston area where the two lived. There are frequent humorous anecdotes comparing their family lives. Gail Caldwell published a previous memoir, A Short West Wind, describing her Texas life. During their years as friends, Caroline published Pack of Two: The Intricate Bond Between People and Dogs. Ms. Knapp’s work includes Gail and her dog Clementine but changes the names. They had coincidentally signed up for a weeklong camp for people and dogs fully immersing in training, agility, group meals and organized play. Eighty people enrolled, CBS news covered the event and Gail describes a group hike as a “Disney movie gone haywire”. A year after Caroline’s death Gail discovered a photograph taken by a mutual friend of their two dogs silhouetted in a window, “a classic dog photo, capturing vigilance and loyalty…in the middle distance of the picture, through the windows and the fields beyond…an outline of Caroline and me walking down the hill…a secret garden revealed only after it is gone.”
