That sank in slowly. I mean, I understood that they'd been worried. Lots of people died in the bombings -- four thousand was the present estimate -- and practically everyone knew someone who didn't come home that day. There were two people from my school who had disappeared.

"Your father was ready to kill someone. Anyone. He was out of his mind. You've never seen him like this. I've never seen him like it either. He was out of his mind. He'd just sit at this table and curse and curse and curse. Vile words, words I'd never heard him say. One day -- the third day -- someone called and he was sure it was you, but it was a wrong number and he threw the phone so hard it disintegrated into thousands of pieces." I'd wondered about the new kitchen phone.

"Something broke in your father. He loves you. We both love you. You are the most important thing in our lives. I don't think you realize that. Do you remember when you were ten, when I went home to London for all that time? Do you remember?"

I nodded silently.

"We were ready to get a divorce, Marcus. Oh, it doesn't matter why anymore. It was just a bad patch, the kind of thing that happens when people who love each other stop paying attention for a few years. He came and got me and convinced me to come back for you. We couldn't bear the thought of doing that to you. We fell in love again for you. We're together today because of you."

I had a lump in my throat. I'd never known this. No one had ever told me.

"So your father is having a hard time right now. He's not in his right mind. It's going to take some time before he comes back to us, before he's the man I love again. We need to understand him until then."

She gave me a long hug, and I noticed how thin her arms had gotten, how saggy the skin on her neck was. I always thought of my mother as young, pale, rosy-cheeked and cheerful, peering shrewdly through her metal-rim glasses. Now she looked a little like an old woman. I had done that to her. The terrorists had done that to her. The Department of Homeland Security had done that to her. In a weird way, we were all on the same side, and Mom and Dad and all those people we'd spoofed were on the other side.

I couldn't sleep that night. Mom's words kept running through my head. Dad had been tense and quiet at dinner and we'd barely spoken, because I didn't trust myself not to say the wrong thing and because he was all wound up over the latest news, that Al Qaeda was definitely responsible for the bombing. Six different terrorist groups had claimed responsibility for the attack, but only Al Qaeda's Internet video disclosed information that the DHS said they hadn't disclosed to anyone.
