Choose between two challenges and receive both a physical box and a digital app to help guide you through landmarks such as Burgos Cathedral, Plaza Mayor, and Arco de San Juan. Before your adventure, receive a physical box posted to your address that contains reports, maps, photographs, and letters. Download the digital app and discover videos, games, clues, and information about Burgos' landmarks. Combine the app and physical materials to solve the mystery. You can choose between two different options: Masked MurdererInvestigate the identity of a serial killer who has killed several young women, broadcasting the murders on social media and moving their bodies to well-known places in Burgos such as the Cathedral, Plaza Mayor, Arco de San Juan, and Paseo del Espolón.
