La Feritoia o Studio sui Possibili Finali: Finale Aperto; Finale Chiuso (The Slit or Study about Probable Endings: Open End; Closed End ) is an interactive story experiment made during an art residence in the former Clares Order convent in Caramanico. Twenty notes from a diary are placed around the place. The reader can look for clues to be able to make out a story that took place in the convent a long time ago. Only one of the pieces of evidence, a letter with a key inside, asks the audience's participation to determine a choice: escaping from the convent or staying inside? In that exact moment the past story and the present one are connected and the reader becomes narrator and protagonist.
