PART 1

At 1:58 a.m., Harlan Mercer woke up to the glow of his phone on the nightstand.

The house was silent. For a moment, he thought it was only an alert.

Then he saw the name.

Sadie.

Not his son Wesley. Not his daughter-in-law Maren.

Sadie, his eight-year-old adopted granddaughter, who almost never called anyone without permission.

He answered immediately.

“Sadie, sweetheart? What’s wrong?”

At first, he heard only small, uneven breaths.

Then her weak whisper came through.

“Grandpa Harlan.”

Something inside him tightened.

Harlan had spent nearly thirty years as a court-appointed family advocate in Oregon. He knew children often told the truth carefully. They did not always say, I’m scared. Sometimes they said, I’m sorry.

“I feel so hot,” Sadie whispered. “And when I close my eyes, the room moves.”

Harlan sat up fast.

“Where’s your dad? Where’s Maren?”

Sadie went quiet.

“They went to Florida,” she finally said. “For Carter’s birthday.”

“With Carter?”

“Yes.”

Harlan closed his eyes, forcing his anger down where Sadie could not hear it.

“Are you alone in the house?”

“They left medicine on the counter,” she said quickly. “And Mom wrote me a note.”

That sentence made him go still.

“What does the note say?”
