The moon cast an eerie glow over the tranquil lake. The night was still, save for the distant owl's hoot. A lone figure emerged from the shadows, clutching a knife. The blade glinted menacingly in the pale moonlight, razor-sharp. The figure crept silently towards the unsuspecting victim, heart pounding. A scream pierced the night, shattering the peaceful silence. Blood pooled on the ground, seeping into the dirt. The killer fled, leaving behind a gruesome crime scene. Detective Sarah Jones arrived, her face grim and determined. She knew this was just the beginning of a nightmare.
