Maria: "Estoy muy perturbada. No quiero hablar de ello, pero anoche vi cosas extrañas en la plaza." Hunter: "I don't speak Spanish. Tell me in English what you saw." Maria: "Vi sombras cerca de la fuente y oí un grito ahogado; después la plaza cayó en silencio. Alguien dejó una cámara en la banca y se fue." Hunter: "A camera? What are you talking about? Was anyone with you?" Maria: "Mi cámara está conmigo ahora. Yo solo quería fotografiar el festival, pero todo se siente mal, como si algo malo estuviera por pasar." Hunter: "Any detail helps. Where exactly did you see the shadows moving?" Maria: "Cerca de la torre del reloj, entre las sombras; parecían seguir a alguien." Hunter: "I need to take this call." Hunter: "I have to go for now. I'll circle back when I can."
