Jane Austen gave Lydia Bennet no interior. She is the reckless one, the embarrassment, the cautionary tale — and the novel moves on.
This is the fourteen days she spent in London.
Lydia is sixteen, certain, and entirely right about what she knows: she was chosen, specifically, for herself, by a man whose ease in any room confirms everything she has ever believed about being wanted. She is going to be Mrs. Wickham. Shortly. She has his word. She is composing the letter to Kitty in her head — the road from Brighton, the east window onto Edward Street, all of it — and she will write it when she has the date.
She is not going to have the date.
The reader holds what Lydia cannot see: the payment runs from Darcy — who does not want her — to Wickham, who is using her. What she reads as being chosen is its exact opposite. The arrangement has nothing to do with who she is.
For fourteen days she is in a room on Edward Street, learning it the way she knows Longbourn — not from looking carefully but from having been there. The devotional tract on the shelf. The bonnet on the windowsill. The crack in the step of the house opposite. His knock: three beats, close together, at the height of a man who knows the person behind the door is there. She would know it anywhere.
When the knock comes, it is two beats.
She does not name what it is. She knows what it is not. She gets up. She crosses the room.
