The rain starts at 11:04, exactly like always. Detective Mara Cole stands under the same broken awning across from the laundromat, pink neon flickering on the wet street. She has lived this hour forty times now. In sixty minutes, a man named Elias Voss dies in the apartment above. She has never saved him. Tonight she swears she will. The clock ticks. She steps off the curb.

Mara runs straight for the building and pounds up the stairs. She kicks Elias's door and bursts in. He's alive, mug of coffee in hand, staring at her like she's lost her mind. 'You're going to die in an hour,' she says, badge out. 'Help me stop it.'

Elias bolts. He thinks she's the killer come early. He shoves past her, sprints down the stairs, and runs out into the rain. Mara chases, shouting his name, but he darts into traffic on the wet street.

Brakes scream. A van clips Elias and he goes down hard in the road. Mara drops beside him, but the lights up and down the street are already dying toward 11:59. He grabs her sleeve. 'It was never the killer,' he gasps. 'It's you. It's always you.' Then the rain starts again at 11:04, and she's back under the awning, his words ringing in her ears.
