My Duck Is Dead

Pierre, a young man of privilege, whose anonymously-published novel is a hit and who's about to marry his blond cousin, Lucie, abandons all when a dark-haired vagrant tells him her secret late one night in the woods: that she is Isabelle, his sister, abandoned by their father. Pierre breaks off with Lucie and his doting mother, heading for Paris with Isabelle, intent on knowing the dark side of human nature. He begins a novel, sending chapters under a pseudonym to his publisher; his relationship with Isabelle moves beyond the fraternal; and, in winter, the frail Lucie comes to live with them. Family jealousies mount, and Pierre may have discovered despair instead of the truth.
