My 10-year-old son disappeared on the walk to Grandma's for Friday dinner — a month later, his missing clothes surfaced in her trash bin.

For a second I couldn't get a word out. I just held the jacket up between us with both hands, the way you'd hold up evidence.

"How do you have this?" I finally said. "You told me he never came. You sat across from me and said it to my face."

Sharon backed up a step into her own hallway. Her hands were trembling.

"Come inside," she said. "Please, Erin, come inside."

"No." My feet didn't move. "You tell me right here on this porch. Where is my son?"

She started to cry — not delicate tears, but the kind that come up from somewhere deep and ugly. The kind that look exactly like guilt.

"He did come," she said. "He made it here. He was fine, Erin. I swear to you on my life, he was fine when he got to me."

The porch seemed to tilt under my feet.

"Then where is he now?"

Sharon pressed her palm flat against her chest. "His father called me that afternoon. Before Caleb even got here. He said he was coming to take him. He said if I warned you, he'd—"

She stopped herself.

"He'd what, Sharon?"

She shook her head hard, tears running down into the collar of her sweater. "He wasn't alone. There was a woman with him. And papers — a whole folder of them. He kept saying it was legal, it was all legal, that I'd go to jail for interfering. I didn't know what to do. I panicked. Caleb's clothes had mud on them from the walk, so I changed him into something clean, and then Dylan was in the driveway and I—"

Behind me, a car rolled slowly up to the curb and stopped.

I turned around.
