In 2113, a riddle will be solved under the Eiffel Tower. Matthew Syed tells the story of a riddle hidden in the video game Trials Evolution (Ubisoft Redlynx) that became a worldwide treasure hunt that’s yet to be solved, as he considers the role of legacy.

Matthew asks how thinking beyond our lifetimes could make life in the present more impactful and might also challenge us to consider how we meet the problems of the future.

With Antti Ilvessuo, creator of the riddle, co-Founder and ex-creative director of RedLynx; Brad Kirby, Trials Evolution super fan and expert aka Professor FatShady; Dr Philip Cozzolino, University of Essex; and Kimberly Wade-Benzoni, Professor of Management and Organizations and Center of Leadership and Ethics Scholar at the Fuqua School of Business at Duke University.
