House alum Lisa Edelstein is moving from the hospital room to the boardroom by guest-starring on CBS’ modern-day Sherlock Holmes revival, Elementary. Dropping by in the seventh episode of the season, Edelstein will play a charismatic CEO of a high-end PR consultancy named Heather Vanowen.

Vanowen is labeled as a smart and confident businesswomen, who will cross-purposes with the brilliant detective Sherlock Holmes (Jonny Lee Miller) during his investigation into a deadly bombing that appears to be linked to her company.

Butting-heads with eccentric geniuses is nothing new for Edelstein, who is probably best known for her role as the uptight hospital administrator Dr. Lisa Cuddy on Fox’s long-running medical drama, House. Fans of the superhero-genre may not readily recognize Edelstein’s face, but perhaps remember her voice work as Lex Luthor’s Amazonian bodyguard/personal assistant, Mercy Graves, in Superman: The Animated Series, Justice League and Justice League Unlimited.

Following the House finale, Edelstein appeared in a multi-episode guest-spot on The Good Wife as Will Gardner’s (Josh Charles) feisty ex, Celeste Serano; she also appeared on Children’s Hospital as both herself and her popular House character, Lisa Cuddy. This year Edelstein co-starred in the Lifetime movie, Blue-Eyed Butcher.

Callie Thorne

Also joining Edelstein for some Sherlockian-shenanigans is actress Callie Thorne (Necessary Roughness) who pops in around episode 6 as Terry D’Amico, a veteran NYPD detective and Captain Gregson’s (Aidan Quinn) former partner. It turns out that she and the captain impulsively imprisoned the wrong man for a string of deadly home invasions years ago. Currently, Thorne’s character is excepted to be a recurring role.

Elementary stars Jonny Lee Miller as the brilliant (and recently sober) detective Sherlock Holmes, who is currently living in New York after attending rehab. Actress Lucy Liu stars as Dr. Joan Watson, who lives with Holmes as his “sober companion” to assist his transition from rehab into regular life. Last week Elementary’s premiere episode pulled in a total of 13.4 million viewers and a 3.1 demo rating, which placed the CBS’ updated Holmesian drama at second (on both counts) for any new drama series.
