The message arrived at 2:47 a.m., which was the first sign something was wrong.

Nora had been awake anyway, sitting at her kitchen table with cold coffee and a stack of bills she couldn't pay. When her phone lit up, she thought: Cass. It has to be Cass.

It wasn't.

UNKNOWN NUMBER: The key you found isn't for a door.

She stared at the screen. Her thumb hovered. Then she typed back: Who is this?

Three dots appeared. Disappeared. Appeared again.

UNKNOWN NUMBER: Someone who knew your mother.

Nora set the phone down carefully, as if it might shatter. Her mother had been dead for eleven years. There were no loose ends — she'd made sure of that. Packed the clothes, sold the house, buried everything that hurt in a place she'd stopped visiting.

But the key.

She pulled open the junk drawer with both hands and dug past takeout menus and dead batteries until her fingers closed around it. Small. Brass. The kind that opened nothing she'd ever found. Her mother had pressed it into her palm the last morning they'd spoken, when Nora was seventeen and walking out the door and didn't look back.

Keep it, her mother had said. You'll know when.

She hadn't known. Not in eleven years.

She picked up the phone.

NORA: What does it open?

The response came fast this time, like whoever it was had been waiting.

UNKNOWN NUMBER: A safety deposit box. Box 1147. First Federal on Greer Street. You have until Friday before the contents are destroyed.

Nora looked at the clock.

Thursday. 2:49 a.m.

She had twenty-two hours.

She was already reaching for her keys.
