The vacation is over. And when the vacation is over, you go home. But where is home? Technically Houston, the suburb of Tanglewood. But Houston doesn't feel like home anymore. The Houston house has a hole in it now. A hole that moves from room to room.

The thought of Penn Cage helpless would shock most people who know me. At thirty-eight years old, I have sent sixteen men and women to death row. I watched seven of them die. I've killed in defense of my family. I've given up one successful career and made a greater success of another. I am admired by my friends, feared by my enemies, loved by those who matter. But in the face of my child's grief, I am powerless.

Taking a deep breath, I hitch Annie a little higher and begin the long trek back to the monorail. We came to Disney World because Sarah and I brought Annie here a year ago-before the diagnosis-and it turned out to be the best vacation of our lives. I hoped a return trip might give Annie some peace. But the opposite has happened. She rises in the middle of the night and pads into the bathroom in search of Sarah; she walks the theme parks with darting eyes, always alert for the vanished maternal profile. In the magical world of Disney, Annie believes Sarah might step around the next corner as easily as Cinderella. When I patiently explained that this could not happen, she reminded me that Snow White rose from the dead just like Jesus, which in her four-year-old brain is indisputable fact. All we have to do is find Mama, so that Daddy can kiss her and make her wake up.

I collapse onto a seat in the monorail with a half dozen Japanese tourists, Annie sobbing softly into my shoulder. The silver train accelerates to cruising speed, rushing through Tomorrowland, a grand anachronism replete with Jetsons-style rocket ships and Art Deco restaurants. A 1950s incarnation of man's glittering destiny, Tomorrowland was outstripped by reality more rapidly than old Walt could have imagined, transformed into a kitschy parody of the dreams of the Eisenhower era. It stands as mute but eloquent testimony to man's inability to predict what lies ahead.
