Isabella: Sono turbata e spaventata. Qualcosa di brutto è successo qui durante la Festa delle Mele. Non posso dire di più. Hunter: I don’t speak Italian. Could you tell me in English what you saw? Isabella: C’era una figura alta, avvolta in un cappotto scuro. L’ho vista aggirarsi tra la folla vicino al tendone. Hunter: What did this person do? Did they speak to anyone or come near you? Isabella: Non parlava. Sembrava osservarci da lontano, e quando mi ha fissata, un freddo ha scosso la mia schiena. Hunter: This is worrying. I have to take this call.
