The rain fell without mercy. Streetlights flickered in the gloom. A shadow moved near the alley. Footsteps echoed on wet pavement. A scream cut through the silence. Blood pooled on the cold ground. A body lay motionless, broken. The killer vanished without trace. Dawn crept over the city. No one heard her final breath.
