Rain tapped the library windows while the old clock ticked. Lord Ashcombe sat dead in his chair by the fireplace. A crimson stain spread slowly beneath his polished black shoes. Detective Mara Voss entered moments later with her small notebook. She paused at the threshold and studied the silent room. The butler claimed he found the body exactly at midnight. Mara noticed one wet footprint leading toward the locked balcony. The clock stopped at twelve, yet the fire still burned. She opened her notebook and wrote one name: Lord Ashcombe. Outside, thunder rolled as the murderer watched from the garden.
