Here is the opening scene of a murder mystery, where each sentence has exactly 20 words: Detective Jameson stood outside the mansion, surrounded by police officers, and wondered what horrors awaited him inside the estate's walls. The morning sunlight cast an eerie glow over the manicured lawn, the sound of chirping birds a stark contrast. A uniformed officer approached him, a look of concern etched on his weathered face, and handed him a notebook. The air was crisp with the scent of freshly cut grass, but Jameson detected a hint of something metallic. The mansion loomed before him, its grandeur and beauty marred by the yellow crime scene tape that surrounded it.
