Wiksteria Lane

Unhappy women do dangerous things.

Katherine Irma Mayfair (previously Davis) is one of the main and titular characters of Desperate Housewives. A former victim of domestic abuse, perpetrated by her first husband, a corrupt policeman, Katherine moved to Wisteria Lane with her aunt Mrs. Simms, hoping to get away from her rough lifestyle and be happy. However, unfortunate circumstances led her to pack up in 1995, and leave suddenly, only to return 12 years later, in 2007, with a new family in tow and a big secret weighing heavily on her. Katherine rivaled Bree Van de Kamp for the title of perfect home fairy, and soon moved comfortably into the position of scheming vixen when it came to going about making her ends meet.


Early life[]

According to her driver's license, Katherine was born on September 8, 1963.

One night, while Katherine and her aunt, Lillian Simms were out and Dylan was being babysat by Mary Alice, she discovered that Wayne had visited his daughter and given her a doll as a gift. Furious, Katherine places the doll on top of a wooden bookshelf in her sleeping daughter's bedroom. Wayne returns and Katherine confronts him. As Wayne begins to become aggressive, Katherine violently strikes him across the head with a candlestick and he retreats. Later, Katherine awoke to Lillian's screams from Dylan's room. Upon reaching the room, it is revealed that Dylan, while trying to retrieve the doll, was crushed and killed by the off-balanced bookshelf.

Katherine returns from Paris in the final episode of the series. Over coffee, she explains to Susan, Lynette, Bree and Gaby that after three months of living in France, she and Robin broke up after she eventually realized she wasn't attracted to women. Katherine reveals that she is no longer "in the game", indicating that she is not dating, and is now channeling her sexual frustration into a business - a line of frozen French pastries - which has made her incredibly wealthy. She reveals her reason for visiting...she has a business proposition for Lynette. Katherine is looking for her business to expand worldwide and she wants Lynette to help run the U.S division in New York. She is disgruntled when Lynette turns down the offer because she's back with Tom and attempts to persuade her decsion by letting Lynette know that in the entire time she has known her, Lynette has never been content with a life of "sewing buttons." Katherine reveals that she is in town for 3 days if Lynette decides to change her mind. After some self-examination, Lynette does just that - the Scavos move to New York, where Lynette becomes CEO of the U.S division of Katherine's company. ("Finishing the Hat")


Katherine's identification
Katherine's identification.

When Katherine was introduced to the series, many critics noted that she was very similar to the Bree Hodge character, in that both prided themselves on their domestic skills. Marc Cherry noted that Katherine "was clearly different" before her arrival in the fourth season, which the Susan character confirms when she claims Katherine is "not as fun as she used to be." Her cold exterior is noted by many characters, including Gabrielle Solis, who remarks that Katherine is "smug and 'holier than thou'" and is "getting a reputation around [the neighborhood] for having a stick up [her] ass!" Though Katherine immediately has conflicts with the other women on the street, most notably Bree, she eventually develops close friendships with her neighbors. Nevertheless, her rivalry with Bree continues, but as a natural part of their sisterly relationship. In the sixth season, however, Katherine "[morphs] into the person the housewives have to hate" in the absence of the Edie Britt character.


[To Dylan]: Regardless, I am still your mother. And while you're under my roof, you will obey my rules.

—Katherine, You Can't Judge A Book By Its Cover

[To Robin]: Just because I enjoy having sex with you doesn't make me a lesbian!!

—Katherine, My Two Young Men

Katherine: What are you still doing here? I thought you found a motel room.
Adam: I did, but I wanted to set something straight before I go. I'm not leaving before you want me to, I'm leaving because I'm walking out on you.
Katherine: Oh, is that how we're gonna play this? Fine, whatever, you're leaving me.
Adam: I am, and here's why. You blamed what happened on your ex-husband, and I believed you. You told me it was all his fault, and then I find out it was yours. We are about even in the betrayal department now. In fact, I think you win.

Behind Closed Doors[]


Delany auditioned for the series' pilot episode in 2004 for the role of Bree Van de Kamp. Creator Marc Cherry thought she delivered "a fantastic audition." Delany was offered the role but rejected it three times. Delany has since insisted that she was not ready to do another television series at the time and that the character of Bree was too similar to her character on Pasadena. The role eventually went to Marcia Cross, Cherry's second choice. Delany reportedly regretted not accepting the part.


When Cherry was developing Katherine, a character with "a lot of Alpha female qualities and some slyness and darkness," he offered Delany the role. She accepted the role and remained on the series until the end of the sixth season. Following her multi-episode guest role on another ABC series, Castle, network executives offered Delany the lead in a new pilot for the 2010-2011 television season. Delany filmed the pilot for Body of Proof in April 2010; her absence in Desperate Housewives was explained by having Katherine and her girlfriend, Robin Gallagher, leave town indefinitely. In May, ABC picked up Body of Proof for thirteen episodes; thus, Delany did not return for the seventh season of Desperate Housewives as a series regular. Delany admits that her exit from the series was quick, but insists that she may return to the series at some point, regardless of whether or not her new series is successful.



  • Bree Van de Kamp and Katherine Mayfair, often depicted as rivals, share many similarities beyond just excellent cooking:
    • Both have married doctors.
    • The first husbands are now dead, with the second husbands having left them.
    • Both have red hair (although in Bree's case it's unnatural).
    • Both have had romantic relationships and/or been engaged with one of Susan's (at the time) ex-husbands.
    • Both have been patients at psychiatric hospitals.
    • Both have daughters who eventually had a baby of their own (though, in Bree's case, it's her biological daughter).
    • Both tried to pass off another child as their own.
  • Marc Cherry said that he was originally going to make Katherine and Mike marry, however, fans said that it had better have been Susan that he married.
  • Susan and Mary Alice knew Katherine previously when she lived in Wisteria Lane at least 12 years before season 4. However Bree was also living on the street at the time (as she lived on Wisteria Lane from 1994), but it seems like Katherine and Bree knew each other from season 4.
  • The character received media attention when she was involved in the series' first lesbian relationship. Besides, she can be considered bisexual, as she had several husbands and a girlfriend.
  • Katherine is the only housewife to return after departing from the series and main cast.
