Born in Spain, she is fluent in Spanish and does not yet know any English. She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude.

Maria: "No, no... esa mujer. La del abrigo azul. La vi anoche, cerca del embarcadero." Hunter: "You know her?" Maria: "No la conocía. Estaba mirando el lago. Y entonces apareció ese hombre detrás de ella." Hunter: "A man? Slow down. When did this happen?" Maria: "No sé quién era. No le vi la cara." (She clutches her camera, then turns its screen toward him.) "Pero estaba allí. Mire. Aquí." Hunter: "Is this her?" Maria: "Sí. Y él... detrás. Mire, aquí, en el borde." (Her finger trembles against the screen.) "Después desaparecieron los dos. Yo oí algo en el agua." Hunter: "I don’t understand you." (He studies the photograph, then points to the figure.) "This man. Where?" Maria: "Por allí." (She points past the cafe window toward the lake.) "No vaya solo. Por favor, no vaya solo." Hunter: "You’re saying he went that way?" Maria: "No, no me entiende." (She shakes her head, eyes shining.) "La foto. Tiene que ver la foto." Hunter: "I am looking at it. You’re sure this was last night?" Maria: "Sí. Anoche. Y ahora ella no está." (She presses the camera to her chest.) "No está." Hunter: "All right. I need you to come down to the station and—" Hunter: "Hunter." Maria: "¿Qué?" Hunter: "I have to take this." (He answers his phone.) "Go ahead." Maria: "No se vaya. Espere. Por favor." Hunter: "I’m sorry. I have to go." (He gestures to the camera.) "Keep that safe. Don’t delete anything." Maria: "No entiendo." Hunter: "The photos. Keep them." (He points at the camera, then heads for the door.) Maria: "¡Espere! ¡La mujer del abrigo azul!"
