“But what about Jimmy and Theresa?” I ask. “They wanted to say goodbye. Couldn’t you wait? I can run get them. It will only take a minute.” Theresa is Jimmy’s little sister and she’s really good with Natalie.

My mom shakes her head. Nat’s shrieking has subsided. Now it’s more like the hum of a radio gone haywire. But my mom clearly wants to get her out of here.

I don’t think Nat will go, but she does. She’s still humming, still holding her head, but she’s walking along behind my mother, yes she is.

“Bye, Nat.” I wave stiffly.

“Moose bye. Moose bye,” she says as she toe-walks across the gangplank.

I take a step forward. I know better than to try to hug her. Nat hates to be touched, but I want to go get the Mattamans at least. I promised I’d let them know when she was leaving.

My father puts his hand on my arm. “She can’t take much more hullabaloo,” he murmurs, his eyes on Darby Trixle, who is deep in conversation with the buck sergeant.

My mom waves to us from the starboard side, scooting Nat’s suitcase under the seat. Nat sits down, her eyes trained on her lap. The motor roars to a start and the Frank M. Coxe pulls out fast, carving a white wake in the stirred-up brown water.

We watch until the boat is so small it could fit in the finger of my baseball glove. And then it’s gone.

2. THE SECRET PASSAGEWAY

Same day-Monday, August 5, 1935

There’s nothing like baseball to get your mind off of things you’d rather not think about. The smell of the glove, the feel of the ball, that thwack the bat makes when you crush the ball… It’s enough to cure anything bad that could ever happen. And today is a baseball day, because my friend Scout from school is coming to Alcatraz this afternoon. Scout is Mr. Baseball. He has his own team and he can really play.
