Room 318

A married woman from a wealthy house keeps a secret that fits in a room number. Three one eight is where she stops being the careful wife the family expects, and where a lawyer who knows her in court starts to know her by another appointment. She tells her husband the evenings are work. / Someone in the house has begun asking why those evenings end at the same address. She can close the room, or wait until the family opens the door with a key she did not give them.
