Getting a bullet in the chest may be the least of Beckett’s problems on Castlethis season.

TVLine has learned that Kristin Lehman — a.k.a. Billy Campbell’s right-hand woman on AMC’s The Killing — has been cast as a potentially recurring love interest for Nathan Fillion’s titular sleuth.

Lehman’s character, whose arrival was first teased in last week’s Ask Ausiello, is described as a “gorgeous, sexy, sophisticated art insurance investigator” who takes an immediate liking to Castle (but who is also harboring a surprising past).

As many of you have pointed out below, the casting reunites Fillion and Lehman for the first time since their brief test Drive on Fox four years ago.

Castle‘s fourth season launches Sept. 19 at 10/9c on ABC. [SOURCE]
