Who is the wife in Home to Marie from the collection, What Was Mine?

To pay her husband back for the times, years earlier, he has been home late for dinner, the wife arranges a party, even hiring caterers, but invites no guests and then leaves at the time the "party" is to start. The ending of the story adds to the reader's sympathy for the husband, as it recalls his staggering "home to Marie" after being brutally mugged.
