Model response

Inspector Vale found the library door locked from within tonight.
Rain tapped the windows while the household gathered downstairs quietly.
Inside, Lord Ashcombe lay beside his unfinished letter, smiling faintly.
His teacup remained warm though his fingers had turned blue.
Vale noticed one muddy footprint inside, directly beneath the window.
Then someone upstairs began playing the dead man's piano again.
