Melinda Clarke is taking advantage of the end of “The O.C.” by returning to her role as professional dominatrix Lady Heather on “CSI”. It will be her fourth time playing the character. Storylines revolving around her have frequently hinted at a strong connection between Lady Heather and CSI Gil Grissom; one episode in particular implies an overnight romp.

Watch for Lady Heather to possibly throw a monkey wrench into Grissom’s secret relationship with fellow CSI Sara Sidle on May 10th.
