The actress will play a wealthy museum benefactor who becomes a suspect in a murder investigation. This is the same episode that features The Killing‘s Kristin Lehman as an art insurance investigator and a potential lust interest for Nathan Fillion’s titular detective.
Like Fillion, Tuck got her first big acting break on One Life to Live. Although the two never appeared on the soap at the same time, their characters were half-siblings via Viki.
Castle‘s fourth season launches Sept. 19 at 10/9c on ABC.
