She raised one finger to her lips and then slowly shut the door.

He understood the gesture as a warning, not an invitation.

He took Owen to school by a different route and spent the rest of the morning wondering who could frighten Frank enough to make him start a fire in daylight.

Chapter 3 — The Address That Survived

The surviving address belonged to a building Daniel had not entered in twenty-five years.

Officer Navarro called at lunchtime and told him that the legible portion appeared to read Bellwether Records Annex, 14 South Quarry Road.

She was careful to say that the address alone did not establish what the envelope contained or who had mailed it.

Daniel sat at his desk with his phone against his ear and stared at the framed photograph of Elise beside his monitor.

Bellwether Records had once been the private archive of the Bellwether Children’s Choir, a charitable organization that toured the Midwest during the 1990s.

Daniel’s mother, Helen Mercer, had worked there as a bookkeeper until she disappeared from the staff roster after a devastating bus accident.

He had been sixteen when his mother arrived home one afternoon carrying a cardboard box full of invoices and told him never to trust a man who smiled during a memorial service.

His father called the remark stress and urged her to rest.

Within a year, Helen had left their family without an explanation that satisfied anyone.

She wrote three letters to Daniel after moving away, but his father burned them unopened in the fireplace.

Daniel had spent most of his adult life resenting both parents for the silence.

He had never returned to the old records annex because he believed whatever happened there belonged to a family he had worked hard to outgrow.

Now someone had mailed him a letter from its address, and Frank had risked arrest to destroy it.

He asked Navarro whether she recognized the return address or the green stamp.

She said investigators would examine the charred paper, but she could not promise that a laboratory could recover the contents.

Daniel thanked her and hung up.

Owen came home to find his father searching old boxes in the guest room closet.

A dry packet of photographs lay open beside a faded choir program.

“Was Grandma part of this?” Owen asked.

Daniel nodded without looking up.

He realized he had told his son almost nothing about Helen except that she had loved crossword puzzles and lived far away.
