Here is a 212 word opening scene for a murder mystery with each sentence containing exactly 20 words: John walked into the quiet, empty library and sat down at a table. He pulled out a book he had checked out recently and began to read in the stillness. After a few minutes, he was interrupted by a loud crash from the aisle behind him that pierced the silence. Startled, he quickly got up from his seat and rushed over to see broken glass covering the floor near a fallen bookcase. As he examined the scene, he noticed a hand sticking out from under the heavy, wooden shelf. He bent down to get a closer look and saw the body of a woman hidden beneath, motionless and covered in blood. Police were called to the scene and began investigating the suspicious death inside the public building that was usually uneventful.
