He knows she is in the elevator before the doors open.

Not from the security feed — though he has checked it twice in the last hour, with the specific and slightly humiliating frequency of a man waiting for something he will not admit he has been waiting for. From the building itself — the shift in air pressure, the sound of the elevator mechanism engaging at the lobby level, the specific weight of a person who has been here three times before and whose presence has become, over those visits, something his senses have catalogued with a thoroughness he finds disproportionate and has not been able to reduce.

He sets down the book.

He has read the same page four times.

This is new. He has not been unable to read for approximately two hundred years. He is noting it with the careful attention of a man who has learned that the small symptoms are the relevant ones. The large things announce themselves. The small things arrive quietly and are already structural by the time you notice them.

He has noticed.

The elevator opens.

He is at his desk when she enters — lamp on, the appropriate papers in front of him, the contacts in, the expression of a man who was working before she arrived and has paused with precisely the right degree of polite accommodation. He has been arranging himself into this picture for eleven minutes. He has chosen not to examine the eleven minutes.

She comes through the penthouse the way she always does — looking at the room before she looks at him. Most people look at him first. He is, he is aware, the kind of face that rooms look at first. She looks at the room. She assesses the space before its occupant, with the attention of someone who has learned that rooms tell you things that people have decided not to.

His room has told her things.

He has been carefully managing what things.

She reaches the sitting area. He gestures to the chair across from him — the same chair, three visits, not offered to anyone else since.

"Detective," he says.

He reaches for the decanter. Pours two glasses without asking. Sets hers on the table.

He looks at her.

Three hundred and forty-one years old. He has sat across from kings and criminals and people who were both, and he has read all of them — the comprehensive reading of a man who has been studying human beings since before most human institutions existed. He has never encountered anyone who looked back the way she looks back.

She is looking at him now.

He holds it.

The contacts are in. He is aware of what is underneath them. He is aware that she has seen what is underneath them and wrote it in her notepad, which is in the bag beside her chair, and that at some point tonight she is going to open it.

He finds he does not mind.

This is the most alarming thing.

He was preparing to leave this city. Had a name chosen. A city. A backstory.

He picks up his glass.

"You have new questions," he says. Not a question. She always arrives with them already formed, already tested against whatever she found between visits. The preparation of someone who thinks between conversations and brings the thinking with her.

He finds this the most interesting thing that has happened to him in a very long time.

"Ask," he says.

And settles back.

And waits.

With considerably more interest than he intends to show.

And slightly more than he manages to hide.
