Elizabeth Is Missing by Emma Healey

Maud, an aging grandmother, is slowly losing her memory—and her grip on everyday life. Yet she refuses to forget her best friend Elizabeth, whom she is convinced is missing and in terrible danger.

But no one will listen to Maud—not her frustrated daughter, Helen, not her caretakers, not the police, and especially not Elizabeth’s mercurial son, Peter. Armed with handwritten notes she leaves for herself and an overwhelming feeling that Elizabeth needs her help, Maud resolves to discover the truth and save her beloved friend.

This singular obsession forms a cornerstone of Maud’s rapidly dissolving present. But the clues she discovers seem only to lead her deeper into her past, to another unsolved disappearance: her sister, Sukey, who vanished shortly after World War II.

Amongst vividly vague geriatric confusion, parents, children, and clues are brilliantly interwoven until their truths are inevitably revealed and secrets exposed.
