Fifteen years married. One lit window across the courtyard. And tonight, Margot does not want to watch anymore. She wants to be watched. For months she has caught herself looking at the man who reads by lamplight across the way. Then one ordinary Tuesday she tells the one person who matters, her husband, and Theo does not laugh, does not flinch. He reaches over and opens the blinds. What starts as a confession becomes the most honest night of a very good marriage: lamps on, curtains up, fifteen years of shorthand turned all the way up. Nobody strays. Nobody is touched but each other. A marriage catching fire from the inside, with the lights on.
