My ten-year-old daughter complained of a toothache, so I made plans to take her to the dentist. Out of nowhere, my husband insisted on tagging along. During the exam, the dentist kept shooting him strange looks. As we were heading out, the doctor discreetly slipped something into my coat pocket. When I read it later at home, my hands began to shake, and I drove straight to the police station.

I did not sleep at all.

At 3:12 a.m., I stood in the kitchen and realized the cereal box was still on the counter where Thomas had left it before the police arrived.

That stupid detail undid me.
