'CSI' scoop: Lady Heather returns to Sin City!

Image Credit: CBS/Michael Yarish/LandovFirst, a much-anticipated (but all-too-brief) appearance by Gil Grissom, and now Lady Heather! EW has learned that Melinda Clarke will reprise her popular role as a steamy dominatrix for a CSI episode that’ll air in April on CBS.

The (one helluva) story: Human pets are at the center of an investigation by the CSI team. Apparently, a murder occurs within a strange offshoot of the dominatrix world in which rich people pay human beings to be their “pets” (gulp). Lady Heather, now Dr. Lady Heather, becomes professionally involved in the case. The episode was written by CSI creator Anthony E. Zuiker and Ed Whitmore.

Clarke last played the role of Lady Heather in the “Leave Out All the Rest” episode that aired in November, 2008. She’s now a regular on CW’s Nikita. The actress told EW earlier that she’s feeling pretty optimistic about another season of the butt-kicking drama.
