Thirty years ago, in the dead of night, a group of six Parisian teenagers pulled off what would prove to be a fateful theft. They met up at a small cafè near the Eiffel Tower to review their plans—again—before heading out into the dark. Lifting a grate from the street, they descended a ladder to a tunnel, an unlit concrete passageway carrying a cable off into the void. They followed the cable to its source: the basement of the ministry of telecommunications. Horizontal bars blocked their way, but the skinny teens all managed to wedge themselves through and ascend to the building’s ground floor. There they found three key rings in the security office and a logbook indicating that the guards were on their rounds.
