In Cervisia Veritas is a quest in The Witcher 2: Assassins of Kings.
Walkthrough
In the Kaedwenian camp are three drunk soldiers calling out for a friend of theirs, Odrin. Walk out the Western camp exit to find Odrin passed out along the lake shore, mumbling about a square coin. You have to lead Odrin back into the camp, and bribe the camp guard (30 orens) to get him in or claim Odrin is your captive and he is drunk so you could interrogate him.
Once in the camp, go round up odrin's friend (they show up as green dots on the minimap). In the camp canteen, you must select the correct conversation options or Odrin and his friends will accuse you of spying and refuse to talk.
Ask 'Does Henselt have work for me?' and then say 'The king knows what he is doing' to complete the quest. Other choices will result in a failed quest.
