Anthony Raimondi (pictured) revealed he helped kill John Paul I in Vatican City in 1978
A mobster from the Colombo mafia family claims he helped poison Pope John Paul I with cyanide 33 days into his reign to stop the pontiff from exposing a billion dollar stock fraud scam.
The startling revelation comes from 69-year-old Anthony Raimondi's new novel 'When the Bullet Hits the Bone.'
The scene begins in 1978 when Raimondi, the nephew of infamous godfather Charles 'Lucky' Luciano, was recruited by his cousin Paul Marcinkus, who ran the Vatican bank in Vatican City.
The Vatican bank, formally known as The Institute for Works of Religion, is one of the most secretive financial establishments in the world.
The New York Post reports that Raimondi's job was to learn the pope's daily habits and be there when Marcinkus spiked John Paul's nightly cup of tea with Valium.
Raimondi notes that the Valium worked so well that the pope wouldn't have woken up 'even if there had been an earthquake.'
He said: 'I stood in the hallway outside the pope’s quarters when the tea was served.'
According to Raimondi, John Paul I (pictured) threatened to expose a billion dollar stock fraud scam involving cardinals at the Vatican bank and mobsters
'I'd done a lot of things in my time, but I didn’t want to be there in the room when they killed the pope. I knew that would buy me a one-way ticket to hell.'
Meanwhile, Marcinkus prepared a dose of cyanide for the pope.
'He measured it in the dropper, put the dropper in the pope’s mouth and squeezed. When it was done, he closed the door behind him and walked away,' Raimondi said.

Shortly after, a papal assistant reportedly checked on the pope and screamed that 'the pope was dying!'
At which point, Marcinkus and two other cardinals rushed into the bedroom and pretended to be horrified by what they saw.
Raimondi was asked by Marcinkus and others involved to testify before god that the pope hadn't suffered.
'They said when we die I would be their witness,' he said.
A Vatican doctor would rule that John Paul suffered a heart attack, none the wiser to any alleged foul play.
The elaborate hit came to be because John Paul I allegedly threatened to expose an international fraud scam run by Vatican insiders.
