Model response

The rain fell without mercy. Detective Hana arrived quite late. Blood stained the oak floor. A body lay face down. Nobody heard the fatal shot. Windows remained completely shut tight. Candles burned near the corpse. Something felt deeply, horribly wrong. Hana knelt beside the victim. The man wore expensive shoes. His wallet was still there. Robbery seemed unlikely to her. A single rose lay nearby. Red petals touched cold skin. Hana pulled out her notebook. This case would not wait.
