Here is a 183 word opening for a murder mystery with sentences of exactly 20 words each: It was a dark and stormy night in the sleepy town of Blackwater Falls. A piercing scream shattered the silence and brought the townspeople running to the old Victorian mansion on the outskirts of town. There they found the body of wealthy recluse Agatha White lying in a pool of blood on the floor of the parlor. The French doors leading to the garden were flung open to the wind and rain. "My god, who could have done such a horrible thing?" cried the pastor as he stared in shock at the gruesome scene. The sheriff ordered everyone back outside to avoid contaminating the crime scene as he carefully stepped around the body looking for clues. Lightning flashed overhead as the medical examiner arrived to examine the body and try to determine the time and cause of death. It was clear this was no accident, Agatha White had been brutally murdered in her own home. But who could have committed such a heinous crime and why? A mystery was afoot in Blackwater Falls.
