Amidst the gloomy fog, Detective Marlow stood at the crime scene, a chilling sight before his weary eyes. The victim lay lifeless in the bathtub, his face partially submerged in the crimson-tinted water. Marlow knelt down, his keen gaze examining the gruesome details of the murder. He noticed the deep stab wounds across the victim's chest and abdomen. A twisted, bloodied knife protruded from the victim's left shoulder, embedded to the hilt. Marlow's mind raced, piecing together the events that led to this gruesome discovery. The bathroom mirror was shattered, shards of glass littered across the marble floor. A trail of blood led from the tub to the adjacent bedroom doorway. Marlow gently picked up a broken shard, carefully examining it for evidence. Footprints in the blood were visible on the plush white carpet. Marlow's partner, Detective Russell, entered the room with a somber expression.
