A woman cut ahead of my elderly father at airport security and called him "grandpa" — then two pilots saw him and immediately stopped.

Director Marsh made three calls in the next ten minutes.

I sat in the corner and watched my father.

He wasn't agitated.

That was the thing I couldn't stop noticing.

He was calm in a way that wasn't passive — it was the calm of someone who had been in rooms like this before, who knew that panic cost more than it bought.

He sat with his cane across his knees and his eyes moving slowly around the room, and I understood, for the first time, that the slowness I had always read as age was something else entirely.

It was patience.

It had always been patience.

"You're staring," he said, without looking at me.

"I'm allowed.

You just told a federal director that someone in this airport is using your secret code name to send you a message."

"I told her someone put a note in her folder.

I don't know who's in this airport."

"Does that distinction comfort you?"

"A little." He almost smiled.

"It should comfort you too."

Director Marsh ended her third call and came back to the table.

"I have a car.

We can be at the Pittsburgh field office in four hours."

"We're not going to the field office," Dad said.

"Thomas—"

"Victor won't come out for a field office.

He'll come out for me." He looked at her.

"Ray gave me an address.

A diner.

Victor will be there at six o'clock if I call Ray back and confirm."

"That's six hours from now."

"Yes."

"We can't stay in this airport for six hours if someone here knows who you are."

"We're not staying in the airport." Dad looked at me.

"We're going to a wedding."

I stared at him.

"Emma's wedding is at four o'clock," he said.

"The diner in Pittsburgh is forty minutes from the venue.

We attend the wedding.

We see Emma get married.

Then I go meet Victor." He held my gaze.

"I promised my granddaughter I would be there.

I'm going to be there."

Director Marsh looked like she wanted to argue.

She looked at my father's face and didn't.

"I'll need two agents at the venue," she said.

"Plainclothes," Dad said.

"Emma doesn't need federal agents at her wedding."

"Agreed."

"And nobody tells Emma any of this."

"Agreed."

He looked at me.

I hadn't said anything.

"Are you all right?" he asked.

"I'm trying to decide," I said, "whether I'm furious with you or proud of you."

"You can be both," he said.

"I've had forty years of practice being both things at once."

The wedding was everything Emma had wanted.

The venue was a restored barn outside the city, strung with warm lights, smelling of cedar and early summer.

She walked down the aisle in a dress she'd bought with her own money and cried through her vows in the best possible way.

Dad sat in the front row and held my hand and didn't cry, but his jaw was tight the whole time, and when Emma kissed her husband and turned to find him in the crowd, the look on his face was the most unguarded thing I had ever seen from him.

Afterward, at the reception, he danced one slow song with her.

She had to lean down slightly because of the height difference, and she rested her cheek against his temple, and he closed his eyes.

I watched from across the room.

At five-fifteen, he found me near the bar.

"It's time," he said.

We slipped out through a side door.

A dark sedan was waiting in the gravel lot.

Captain Reeves was behind the wheel.

Director Marsh was in the passenger seat.

I got in the back beside my father.

"How do you feel?" I asked.
