Based on an extraordinary true story – told with the help of the very people who suffered at the hands of Marchese -
Dr Jan Falkowski and his fiancée Debbie Pemberton could think of no-one who would want to stalk them with threatening texts and phone calls. Even when the stalker professed to being in love with Jan, they refused to take her increasingly manic behaviour seriously. That is until she broke into their houseboat and opened the gas taps, threatened Jan's family and attempted to cancel their wedding.
