Write the opening scene of a mystery novel that utilizes a non-linear timeline. The narrative must alternate between three distinct time periods: 24 hours before the crime, the moment the crime is discovered, and the interrogation 10 years later. You must use an unreliable narrator in at least one timeline. Focus on using sensory details and subtle inconsistencies in dialogue to hint at the narrator's unreliability without revealing the truth immediately. Ensure transitions between timelines are distinct but thematically linked.
