For over half a century, Banco Popular was one of the most profitable banks in the world – until one day in 2017, when the Spanish bank suddenly collapsed overnight. When investigative journalist Gareth Gore was dispatched to report on the story, he expected to find yet another case of unbridled capitalist ambition gone wrong. Instead, he uncovered decades of deception that hid one of the most brazen cases of corporate pillaging in history, perpetrated by a group of men sworn to celibacy and self-flagellation who had secretly controlled Popular and abused their positions there to help spread Opus Dei to every corner of the world. Drawing on unparalleled access to bank records, insider accounts, and exclusive interviews with whistleblowers from within Opus Dei, Gore reveals how money from the bank was used to lure unsuspecting recruits – some of them only children – into a life of servitude.
