At Rome, Italy, Chief Ripley orders Carmen and the player to look for Father Pietro Agnelli, the odds-on favorite to replace the gravelly ill Pope, before the Promethians can get their hands or him - or worse, convince him to join them. Unfortunately, the are proven to be too late when they find Pietro's body at the Piazza di Spagna, held in the arms of an statue and branded to death.
Tropes:
- Be Careful What You Wish For: When Carmen complains they don't have any new leads, Ingrid comes to show you a woman on TV about to commit suicide, claiming that Pietro's death has greatly affected her.Ingrid: You needed a new lead, ask and you shall receive…
- Buffy Speak: When Lars deduces the killer didn't have much eumelanin judging by the DNA left in the branding iron, Carmen asks what is "you-mellow-what".
- Call-Back: Brother Klaus reappears as a suspect, while Jacqueline Proust returns as a quasi-suspect instead.
- Card-Carrying Villain: Carmen calls Brother Klaus a card-carrying Promethian, which are a villainous terrorist group.
- Cliffhanger: The case ends with The Bureau discovering the Promethians' master plan involving mass bombing, prompting them to fly to Spain per Jacqueline's advice since the leader and the detonator will be there.
- Continuity Nod: You discover Brother Klaus is at The Vatican after you find the same sunblock he used in Germany.
- Drama Queen: Fiora Tosca, as she faked a suicide attempt because she wanted people to pity her.
- Driven to Suicide: Brother Klaus sets himself on fire in his cell after he's arrested since his mission is now "complete."
- Explain, Explain... Oh, Crap!: When Carmen begins to recap how you've found a notebook with multiple European monuments marked and a prototype bomb in the Venice canal near a bridge where an anti-referendum would be taking place, she slowly realizes this means the Promethians are planning a mass bombing to scare people so they vote "Yes".
- Fake Defector: When you find Brother Klaus, he claims he has turned away from the Promethians thanks to Father Pietro's faith, which turns out to be false when he's found guilty of his murder in the name of the Promethians.
- Falsely Reformed Villain: Klaus tells you he has become a good man thanks to the Church (though you still put him under arrest for being an accomplice in Hans' murder), which is a lie.
- Good Shepherd: Father Pietro might be one of the franchise's purest victims, with the only people badmouthing him being either his evil Promethian killer or his rival for the Pope role. Unfortunately, this led to his death, as the Promethians didn't want such a good man to be the Pope.
- Gratuitous Italian: Since most of your suspects are Italian, this was to be expected.
- Gut Feeling: Jacqueline tries to pass off the fact that she knows Brother Klaus was arrested as this, but Carmen tells her to cut the crap off, so she reveals she's an undercover Promethian.
- High Priest: The case deals with the current Pope on his deathbed and the most likely person to succeed him being murdered, which The Bureau (correctly) assumes has to do with the Promethians.
- Hollywood Nuns: Sister Beppa, a nun who ran a radio show with Father Pietro.
- Interrupted Suicide: You stop Fiora before she can jump off to the Venice canal.
- Intrepid Reporter: Carmen recalls how she was chasing an story involving stolen art the last time she visited Vatican City.
- Mark of Shame: The victim was killed by being branded with a Promethian's symbol, which made him suffer a heart attack.
- The Mole: Jacqueline reveals to you she's a Promethian, intending to learn about and bring them down from the inside if possible, something Carmen finds hard to believe but Chief Ripley judges she's the best lead they've got.
- Monumental Damage: The Promethians' master plan is mass bombing various monuments across Europe (such as the Eiffel Tower or the Tower of Pisa) so people will panic and vote "Yes" in the Referendum for an United Europe, since Carmen deduces people seek unity in times of chaos.
- Obfuscating Insanity: Subverted. Carmen believes Brother Klaus is faking his insanity to avoid being interrogated, but in the end it turns out to be entirely genuine when he commits suicide by Self-Immolation.
- Oh, No... Not Again!: When Sister Beppa chains herself at the bridge (which happens after you prevent Fiora from jumping off it), Carmen asks what's with Italian women performing dramatic scenes at bridges.
- I Owe You My Life: Fiora Tosca, Italy's most beloved opera singer, used to be a street urchin before Father Pietro took her and her family under his wing. For this reason, Fiora attempts to commit suicide when she hears about his death... or she'd want us to believe that.
- Protest by Obstruction: Sister Beppa chains herself to a bridge in Venice to protest against the pro-referendum party, claiming they're the ones who killed Father Pietro.
- Rags to Riches: Subverted. When you first meet Fiora, she says she used to be an street urchin who was rescued by Father Pietro, but we later learn she's just lying to gain sympathy.Fiora: Nothing sells like a rags to riches story… I needed a competitive edge in the opera world… So I made up the story about the begging…

- One of the killer's traits is knowing Dante's Inferno.
- Chapter 3's cover image is a detail from The Creation of Adam.
- Sinister Minister: Cardinal Salieri, whilst not explicitly evil, is still a shady, Pro-Referendum individual with a very apparent case of ambition. Brother Klaus even calls him "a friend" when he gets arrested and thinks he would be the best one suited for the Pope role.
- Someday This Will Come in Handy: When Angela gives you some trivia about branding irons needing be at least 2,000 degrees Fahrenheit to create instant third-degree burns in human skin, Carmen sarcastically responds she'll try to note that someday. Then later when you find a butane torch in the crime scene, Carmen wonders if it was the one used by the killer to "bring the brand up to 2000 degrees Fahrenheit".
- Spaghetti and Gondolas: Some crime scenes have platters of spaghetti and slices of pizza as clues, you visit Venice during the investigation, and even have a gondolier as a suspect.
