I agree that the Holland Handkerchief is the best example, but one other that gets somewhat towards it is Clerk Saunders, where May Margaret sleeps through the murder, and wakes up in the morning to find Saunders dead in her arms.

And in Bruton Town (and versions set in other places), the girl spends some days with her lover's corpse until cruel hunger drives her home to confront her brothers.
