Part confession, part live investigation, Todo Lo Que No Dije invites the audience to pass, read, and even launch postcards as clues in a mystery of memory: what do we owe the people who disappeared from our lives—and what do they still owe us? Following a trail from a flea-market message to a Madrid nursing home, this tender, funny, and disarmingly participatory new work turns spectators into collaborators in a case about loss, language, and the courage to call.
