Events of Criminal Case

Constantin was first interrogated after the player and Carmen found an article of him. He was informed of Annette's murder during his lunch, and knew of her photoshoot as well. He allowed it because of how the victim was a high-profile personality, and not just anyone is allowed to use the castle as they see fit. Constantin was worried that with the murder, Versailles will get the wrong kind of reputation.

He was spoken to again after they found a text from him to the victim on her phone. Since it was in French he revealed it meant that he had enough of the photoshoot the victim was holding. He did not like how the victim brought a guillotine into the castle and how she would constantly argue with her photographer, making him worry that something would break. He went on to say that Versailles is a national treasure and believes it should be treated with respect.


Constantin took a photo of Annette before beheading her.

Constantin was later found to be the one who murdered Annette. Constantin hated Carmen's sudden accusation of homicide, but the journalist-turned-detective took time to snap at him with the player's findings during the murder investigation. Constantin tried to frame Grace Goude but Carmen continued her brow-beating at Constantin for the homicide. Money was the key reason as to why Constantin beheaded Annette as he wanted to live his life like a royal instead of looking after historic properties for a living. The same organization that threatened Enid Grimshaw to kill Prince Albert previously offered Constantin a high sum of money if he was able to execute Annette and steal the manuscript for that organization's retrieval. Carmen wanted to know who the party offered Constantin money for blood, but Constantin refrained from saying a word relaying a suspicion Carmen has about an organization having manuscripts for benefit. Constantin only did it for money, and recalled nothing about the theft of the manuscript, but knowing an audit was necessary, Carmen opted to ship Constantin to Judge Adaku for the meantime.

The last time Judge Adaku heard of guillotine use was 38 years ago before events of this game, but Constantin took advantage of the guillotine being in the Hall of Mirrors to execute Annette for money. Judge Adaku threw some Camus beliefs that "no cause justifies the deaths of innocent people", so with those words spoken, Judge Adaku sentenced Perrier to 25 years in jail.

Carmen had to interrogate Constantin as she promised to the player for clues as to where he hid the manuscript at. All Carmen knew was that the same group of people who threatened Enid to kill Prince Albert or else used a torn page from the manuscript Constantin seized. Money was the reason why Constantin opted to return the manuscript to the wrong hands, so she had to initiate the audit and as long as this group was on the loose, given more lives would be a risk. All Constantin remembered was that he left the manuscript at the Louvre gardens, but could not remember the exact spot. The moment Carmen and the player found what Constantin stole, they required Dupont's intervention to decipher as to why the manuscript happened to be important to Perrier.
