TVLine has learned exclusively that the versatile actress — who is arguably best known for her portrayal of Shelly Johnson on the cult classic, Twin Peaks — has landed a potentially recurring role on The CW’s freshman thriller.

Amick will play Greer Sheridan, a “confident, sexy and strong-willed” socialite who once counted Siobhan (played by Sarah Michelle Gellar) as one of her closest friends. Unfortunately, a mysterious incident put a major strain on their relationship and Bridget (posing as her twin sister) makes it her mission to find out what went wrong when the two team up for a charity event.

Amick makes her debut in Episode 11.
