Stories in The Unforgotten, ranging from a novella to flash narratives of merely a paragraph, are populated by a variety of characters. Among them: Luisa, a beloved childhood servant in Peru, who disappears inexplicably. A child writes that her mom has a lover, a grownup word for boyfriend. Gertrude, whose lifelong collection of sophisticated words fades into dementia. Charles, a grandfather in a white nightgown and bobbing nightcap, chases a bull away from his wife’s beloved rose garden. A mother tells her child a story of a joyous snail with a will to live. Adrianna, now a grandmother, reminiscences about a college year in Paris with her best friend who later committed suicide. Henry, working in a research lab, befriends a rat he names Eloise.
