"Lady" Heather Kessler is a former fetish club owner in CSI: Crime Scene Investigation.
In her first appearance, Gil Grissom is immediately interested in her, as she seemed cultured and intelligent. It is obvious that she returns the feeling, and the two have shared many intimate moments together. Whether they have actually had sex is unknown.
Lady Heather has assisted the CSI team on many occasions. In her last appearance, Grissom was surprised to find that she is now a registered psychologist. She assisted the team by pointing out that the murder they were investigating was sexual/fetish related.
In Pirates of the Third Reich, Heather's daughter was found murdered and she pursued her own search for the killer. Grissom caught her as she tried to flog him to death and stopped her from doing so.
She also appeared in Unleashed, helping the team by regarding a murder that involves a sexual fetish for cats. By this point, Sara Sidle and Gil Grissom are married and Sara, who has despised Heather for being the only other woman Grissom has shown interest in, seems to brag about her relationship with Grissom. Meanwhile, as she is now a psycologist, she helps Raymond Langston try to overcome his personal demons regarding his hatred and fear of profilic serial killer Nate Haskell.
