The Halloran rooming house is still smoking when Investigator Edda Voss arrives at dawn. Eight survivors sit on the curb under scratchy blankets, faces black with soot. The landlord's ledger lists nine tenants, nine rent stubs, nine keys collected every New Year. Edda counts the survivors twice. Eight. So where is the ninth tenant, and which clue does she chase first?

Edda walks the line of survivors instead. Eight blankets, eight pairs of red eyes. She asks each one the same simple question: who lived in room 9? Every single person goes quiet. One woman starts to cry. A man stares at his shoes. Nobody answers.

Edda kneels in front of the crying woman. 'You're not in trouble,' she says softly. The woman whispers, 'We promised. We all promised never to say her name.' Then she clamps her mouth shut, terrified, and won't say another word.

Edda doesn't push the woman. She watches the whole group instead. When she says, 'a promise to a living person,' nobody reacts. When she says, 'a promise to the dead,' all eight flinch at once. Now she knows: the ninth tenant died long ago.
