There is something very special about Agnès Morel. A quiet presence in the small French town of Chartres, she can be found cleaning the famed medieval cathedral each morning and doing odd jobs for the townspeople. No one knows where she came from or why. Not Abbé Paul, who discovered her one morning twenty years ago, sleeping on the north porch, and not Alain Fleury, the irreverent young restorer who works alongside her each day—and whose attention she catches with her tawny eyes and elusive manner. She has transformed each of their lives in her own subtle way, yet no one suspects the dark secret Agnès is hiding.
When an accidental encounter dredges up a series of tragic incidents from Agnès' youth, the nasty meddling of town gossips threatens to upend the woman's simple, peaceful life. Her story reveals a terrible loss, a case of mistaken identity, and a cruel and violent act that haunts her past. Agnès wrestles with her own sense of guilt and enduring heartbreak while the citizens piece together the truth about her life.
