Pétur

Pétur is the Icelandic state attorney and the hidden most significant antagonist in The Valhalla Murders. He oversaw the Valhalla boys facility in Borgarnes, being revealed at the end as the serial rapist of the boys at the building, as well as multiple other boys around Reykjavik and Iceland. When he was closed in on, he also murdered Guðmundur to prevent him from revealing the attorney general's identity, framing Kristján for the murder before he was caught.
