|Occupation|| Former Fetish Club Owner|
|Portrayed By||Melinda Clarke|
|First Appearance||Slaves of Las Vegas|
"Lady" Heather Kessler is a former fetish club owner in CSI: Crime Scene Investigation. She has consulted the Las Vegas crime lab on more than one occasion and has been viewed by fans as a potential love interest of Grissom during the seasons before he became involved with Sara.
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 - (although Grissom does mention, in the last ever CSI episode 'Immortality', that "Lady Heather never slept with any of her clients or patients"; which from Sara's surprised reaction to said admission, seems quite telling.)
Lady Heather has assisted the CSI team on many occasions. In a season nine episode, Grissom was surprised to find that she is now a registered psychologist, specializing in sexual counseling. 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, Zöe, 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 psychologist, she helps Raymond Langston try to overcome his personal demons regarding his hatred and fear of prolific serial killer Nate Haskell.
