Model response

Wind howled. Rain lashed.
Victim lay still. Blood pooled slowly.
Detective arrived early. Scene was grim.
She wore a long coat. Her face was stern.
Pockets held a small book. A pen clicked open.
She saw the victim. A jeweler.
Ring missing from finger. His last act?
She knelt beside him. Studied the scene.
Every detail mattered greatly. A faint shimmer.
It glistened on his cheek. A tiny fiber.
Not from his ruined suit. Unknown for sure.
A single red hair. Her brows furrowed.
