"Pope John Paul I [26 August-29 September 1978] had nothing to hide [no paedophilia] and ordered the Vatican Books to be opened. When the chief of the IRA heard this, he jumped up like he'd been stung, saying, 'Oh my God, the Pope's just committed suicide'. He rang the Vatican straight away and demanded passports for his men go to the top of the pile.  "The IRA routinely travel on Vatican passports which are diplomatic documents describing the priest's urgent mission. They are written on vellum [calfskin or goatskin pelts] and say, 'Whoever impedes or obstructs this priest in his urgent mission work shall be consigned to the fires of hell and burn there for ever and ever'."  This holds a lot of power in Catholic countries like France, Belgium and Italy. Authorities will turn a blind eye to a stack of heat-seeking missiles if you are travelling under Papal Bulls - after all, many of those who carry them are killers on a mission for the Catholic Church.
    "The IRA got their paperwork back and the following day I went down to the dairy to get the paper and the headline read, 'The Pope Dies, Great Shock'. He was in office only 33 days. p.178
