Lisa Duffy's "What Matters" explores our notions of exactly that in the telling and remembering of the events surrounding the brief disappearance of the narrator's son. When the little boy gets lost in Central Park, his absence sets off a chain of events both in the search for him and in the narrator's search for the meaning of the events as she relives them. Trust, fidelity, and truth are just some of the ideas Duffy mines for this compelling and compellingly told story.
