Penguin, London 2006, 8vo, orig. omslag, 403 s., engelsk tekst.
«Granted unlimited access to those within Opus Dei’s ranks, gaining a wealth of interviews with its leaders around the world, Vatican insider John Allen finally separates the myths from the facts: the actual use of whips and the cilice; the true extent of Opus Dei’s funds; the identities of its influential members in politics, banking and high office; and how much power this shadowy group really has.» — fra bakomslaget
