The next episode of FX's American Horror Story: Hotel some of history's most infamous serial killers.

What's The Deal With Mr. March And Miss Evers In 'American Horror Story: Hotel'?

The promo for the next episode of American Horror Story: Hotel, titled Devil's Night, features a dinner party scene with the absolute worst guests imaginable. The party features Mr. March (Evan Peters), Jeffrey Dahmer (Seth Gabel), Aileen Wuornos (Lily Rabe) and more.

"To us, the great killers of our time," Mr. March says in a toast.

How Does Lady Gaga's Fiance Feel About Racy 'American Horror Story' Sex Scenes?

John Lowe (Wes Bentley) is cordially invited to the dinner party, at which he asks Mr. March, "What is this, some kind of Halloween trick?"

This episode will feature the welcome return of Rabe, who was featured in the first three seasons of American Horror Story and briefly in the fourth one. The actress played ghost Nora Montgomery in Murder House, witch Misty Day in Coven and Sister Mary Eunice in both Asylum and Freak Show.

Devil's Night will also feature the return of John Carroll Lynch, who played Twisty the Clown in Freak Show. He is ironically dressed in clown makeup again in this promo, but this time he's playing a character far more sinister than Twisty could ever be: John Wayne Gacy.

There is no telling what all these serial killers will do as the congregate in the already creepy Hotel Cortez.

As The Countess (Lady Gaga) tells Alex (Chloë Sevigny) at the end of this promo, "The world can be such an evil place."

American Horror Story: Hotel airs Wednesdays at 10 p.m. ET/PT on FX.
