Silver Tower Apartments 4404
The sound of rain has never been this clear.
You push open the heavy oak door, the groan of the hinges absorbed by the carpet. Only a single floor lamp is lit in the living room, its light spreading across the Persian rug like melted amber. Su He is curled up in the corner of the sofa, the collar of her dark green robe open, revealing her pale collarbones. She doesn't look up, an ancient silver coin flipping between her fingers with precise rhythm—clink.
"You're back. There are noodles in the fridge, cook them yourself."
Her voice sounds like crumpled tinfoil. You put down your soaking wet coat, your gaze falling on the documents scattered across the coffee table—the case number is circled in red pen, and the body in the photo has strange symbols on it. A new case.
And you haven't had dinner yet.

Qin Sen's Call
Qin Sen's Call
Just as you drop the noodles into the boiling water, your phone vibrates.
The screen displays: Qin Sen.
You answer, and before you can speak, his deep voice presses in: "Another body was found under the South District overpass. It's like the previous one, but the killer left something behind. Is Su He there?" You turn to look at the living room. Su He is already standing by the window, drawing the curtains with one hand, the city lights across the curtain of rain blurring into points of light. She seems to have heard.
"Tell him, fifteen minutes."
She doesn't turn around, but you know she is speaking to you.
You repeat into the phone: "Fifteen minutes." Qin Sen pauses for a beat, then says: "See you at the scene." Hang up.
You turn off the stove; the noodles are already mushy.

Symbols in the Rain

The scene is quieter than expected.
The yellow police tape trembles slightly in the wind, the police lights dyeing the rain red and blue. The body lies beside a concrete pillar under the overpass, the white shirt soaked through with blood. Su He squats to one side, her fingers in black kidskin gloves gently parting the victim's collar.
"The third rib is broken, piercing the left lung. The cause of death is pneumothorax. But look here..."
She turns slightly, letting you see the symbol below the victim's collarbone—a scribbled arc, as if carved in a hurry. Your heart sinks suddenly. That symbol, you've seen it on an old medical record from the field hospital.
"You recognize it?" Su He raises her eyes, her light gray irises almost transparent under the lights.
Your throat tightens. You hope you're mistaken.
