Here is a 208 word opening scene for a murder mystery with 10 sentences of 20 words each: The candle-lit study was eerily quiet as Professor Clivedon hunched over his desk, scribbling furiously into his leather journal. A storm raged outside the ivy covered walls of the ancient university building on this dark autumn night. A flash of lightning suddenly illuminated the room and the Professor glanced up, startled by a loud knock at the thick wooden door. Setting down his fountain pen, he hesitantly crossed the room and turned the brass knob to reveal his assistant who was wide-eyed and out of breath. "Professor, you must come quickly! There's been a ghastly murder in the library!" the young man exclaimed in a panicked tone. Grabbing his coat, the Professor rushed from his study, following the assistant's lead through the empty lamp-lit halls. Entering the library, he was confronted by a horrific scene - a woman's body lying in a pool of blood amidst the tall shelves of leather-bound books. Kneeling beside her, the Professor examined the deep stab wounds across her torso, bewildered by her untimely demise. Who could have committed this violent crime within the hallowed halls of the university?
