Karen Duvall

Det. Karen Duvall is a main character in Unbelievable. She is a detective who is investigating a series of similar rape cases along with her partner Grace Rasmussen.

She is portrayed by Merritt Wever.

Personality
Karen is a generally soft-spoken detective whose mission is to help women in need. Unlike many other detectives in the series, Karen is anything but biased.

Karen stands out from her fellow officers in that she has the ability to easily gain a victim's trust. This is immediately demonstrated in her first appearance in Episode 2 when she is able to persuade Amber to provide details of her assault and the identity of her attacker.

However, despite her generally-friendly demeanour, Karen is not afraid to scold her fellow officers, such as when she verbally lashed out at Morris for slacking off during the investigation, saying that, in such disturbing circumstances she 'do(es) expect everyone on (her) team to give (her) 100% of their effort, 100% of the time'.

Karen also seems to be underestimated by others at times. This is because of her being a member of the church and openly expressing faith in tracking down the rapist, triggering sarcastic comments from Grace Rasmussen.

Relationships
Mother of 2 daughters. Husband works in the District Attorneys office (DA's office).
