Events of Criminal Case
God Save the Prince
Klaus was first spoken to after the team found and analyzed a symbol found on a candle, which according to Dupont is some sort of spell. The player and Jack could not find him at first, but he frightened Jack when he popped up. Klaus went on about seeing many things, so Jack thought they were not going to get much out of him at that time; so they simply left for the time being.
Klaus was spoken to again regarding a scroll found on a carrier pigeon saying that the Prince was dead. An analysis from Elliot revealed that Klaus was the one who sent it. The monk explained that once he heard of Prince Albert's death, he sent a message to a fellow believer to celebrate the news. Klaus felt that the Prince represented everything evil in the country, which was why he needed to be destroyed. Jack believed that was a confession to him killing the Prince, but Klaus said he was not a killer but a messenger.
Brother Klaus was revealed to be innocent after the team incarcerated Enid Grimshaw, but was spoken to again about the blackmail letter that was sent to Enid to kill the Prince. When shown the blackmail letter, Klaus reveal it was from a book called the Manuscript, and demanded that he be given the letter. Jack proceeded to arrest the monk until he revealed who wrote the note to Enid. However Klaus had to be let go on account of a lack of strong evidence, plus an expensive lawyer was paid for to represent him. Jack became suspicious of him since he did not expect someone like Klaus to afford an expensive lawyer, and opted to keep an eye on him for the time being.
Klaus was found in trouble after Carmen and the player found some military ID tags which, according to Elliot, belonged to him, given the killer had military training. He was furious to see the player again, and even more so when Carmen referred to him by his actual name. When Carmen wondered if the Promethians had him kill Hans, he said that he was no murderer but just a messenger for the Promethians. He explained that his dog tags were by the castle in the Black Forest because that was his home. But then warned the player that once the Promethians take power, the land will be theirs.
Klaus was interrogated again after the team found traces of albino sunscreen on an effigy of the victim. He said that the fool was just a coincidence, but believed that Hans deserved his death for tormenting him for years. The two of them were children growing up in Bierburg, and he and other children mocked him for his looks making him an outcast. Since then he spent many years alone wishing his demise as well as the others.
Though Klaus was found innocent of committing the murder after the team arrested Johan Schnee, Klaus was still in trouble when the team spoke to him regarding how Promethians deal with traitors; which is by impaling them. He confessed that he gave Johan the idea of murdering Hans by impaling him, but said it was because he betrayed the Promethians. Carmen was shocked to hear that Hans was a part of the cult, but then proceeded to arrest Klaus for his aid in the murder of Hans Vogel. He was later spoken to by Marina in hopes of obtaining details about an attack the Promethians are planning. Marina wanted to know what Klaus wanted out of all this like money or power, but Klaus said that where he was going money had become worthless. He then activated a smoke bomb and escaped the interrogation room, leading The Bureau to send a Code-Red-Alert to find Brother Klaus.
When Shadows Fall
Klaus was found in trouble after Carmen and the player found a candle with a message for the victim with a substance that, according to Lars' analysis, turned out to be the same sunscreen he used in Germany during Hans Vogel's murder investigation. He was surprised the player and Carmen removed the candle he placed down, which was supposed to absorb negative energy coming towards Father Agnelli. Carmen wondered why Klaus was not wearing a Promethian necklace anymore, to which Klaus responded that he left the Promethians thanks to the victim. Carmen had trouble believing him, but proceeded to arrest him for aiding and abetting the murder of Hans Vogel back in Germany.
Klaus had to be interrogated regarding an argument he had with the victim recorded at the primary crime scene. Klaus explained he was just trying to convince the victim to vote for the Referendum. He felt it was the least he could do since he claimed the victim made him change his ways. Though Klaus believed the victim was misguided in his beliefs about the Referendum, he said he never intended to harm him out of respect for him.
Despite all the claims he made that he changed for the better, the evidence pointed to Klaus as the killer of Father Agnelli. After Klaus denied killing Agnelli, he gave in and told the team that the Promethians did not want Agnelli to become the next pope as he was against the unification of Europe. He endorsed Cardinal Salieri instead. In court, Klaus refused to admit anything about the Promethians, so Judge Adaku sentenced him to 25 years in prison.
Just when Chief Ripley and Carmen agreed that Klaus was also the one responsible for blackmailing Johan Schnee and Enid Grimshaw to commit their respective murders, Jacqueline Proust called the detective saying she had “become a member” of the Promethian cult. With the feeling that something would happen in Spain, Jacqueline told Carmen to talk to Klaus in prison about the cult’s plan. Unfortunately, the team could not get anything out of Klaus as he burned himself to death during the talk, saying that the plan had ended where it started.
