Where does The Witcher: The Lesser Evil fit?

In search of a reward, Geralt brings the carcass of a slain creature to a small town where he is told it may be of use to the local sorcerer - but the mage isn't who he is alleged to be. In hiding for his life, he requests Geralt's help in slaying the monster who seeks to murder him - a young woman said to have been born under the Curse of the Black Sun - a prophecy of inborn evil. He declares that she is more a monster than the creature presented before him. Geralt later encounters the woman, who asserts that it is the sorcerer who is the true monster - committing unspeakable crimes at the behest of his superstitious beliefs. With the boundaries blurred between the evil that is done and the evil done in return, Geralt is met with a quandary. The face of evil is ever-changing and his verdict, whether by choice or by force, can only lead to tragedy.
