At the mall, my 11-year-old suddenly grabbed my hand and whispered, “Mom—quickly, behind that pillar. Don’t move.”

I wanted nothing important stored only on my phone.

Then I made one final call.

Daniel’s older sister, Claire.

She listened to the recording twice.

Then she said quietly, “Laura, I know who that man is.”

The following morning, when Margaret and Daniel walked into our kitchen, they both went pale.

PART 2

Claire arrived at our house at 6:45 the next morning, fifteen minutes after Daniel was supposedly already at work.

Except Daniel hadn’t really gone.

At 7:10, he came back through the garage, saw Claire sitting at our kitchen table, and stopped dead.

Five minutes later, Margaret appeared at the front door.

She tried using the spare key she still believed worked.

The lock rejected it.

I opened the door myself.
