Unfortunately, fans of "Criminal Minds" will have to wait an extra week for the next new episode. But it will be worth the wait because it promises to be intense as the BAU dips into the ugly side of politics after a congressman's wife goes missing.

Last week's episode, "Breath Play," took a spin on the popular novel-turned-movie "Fifty Shades of Grey" as the BAU hunted down a serial killer with a sick sexual fantasy in Wisconsin. The unsub turned out to be a suburban father and husband who tricks his victims into believing that he can fulfill their erotic fantasies based on a best-selling book called "Bare Reflections." However, the suspect gets off on choking women to death, notes Entertainment Weekly.

Jennifer Love Hewitt's real-life pregnancy was also written into the show as Meg started acting rebellious once she realized that Kate was pregnant. She tried to pierce her own belly button and told Kate to leave her alone. However, Kate reassured her that her new baby will not affect or damage their relationship.

The next episode of "Criminal Minds," "Rock Creek Park," will revolve around the disappearance of an elected official's wife. As a result, the BAU will investigate a congressman's political foes.

The March 25 episode will also feature a big-name guest star. According to Carter Matt, the synopsis reads as follows:

"When the wife of an up-and-coming congressman disappears, the BAU investigates his political enemies as possible suspects, on CRIMINAL MINDS, Wednesday, March 25 (9-10 p.m., ET/PT) on the CBS Television Network. Academy Award-nominated actress Tess Harper ('Crimes of the Heart,' 'Tender Mercies') guest stars as Dinah Troy, the congressman's mother."

Season 10, Episode 16 of "Criminal Minds," "Rock Creek Park" will air on Wednesday, March 25, at 9 p.m. EST on CBS.
