Detective Jameson stood at the crime scene, surveying the carnage that lay before him in the dimly lit alleyway. The body of a man was sprawled face down on the cracked pavement, blood pooling around his head slowly. He knelt beside the corpse, his eyes taking in every detail of the gruesome sight before him intently. The man's dark suit was rumpled and stained, his tie askew and his white shirt now crimson in color. Detective Jameson's experienced gaze moved to the man's outstretched hand, fingers curled around a small piece of paper. He gingerly pried the note from the dead man's grasp, careful not to disturb any potential evidence carefully. Unfolding the paper, Jameson read the cryptic message scrawled there in red ink with a slight frown. The words "They're watching you" were written in a shaky, uneven hand, sending a chill down Jameson's spine. He refolded the note and tucked it into his pocket, his mind already racing through possible suspects and motives. The detective knew this was going to be one complex and dangerous case, one that would test his skills thoroughly.
