"American Horror Story: Hotel" is finally back tonight after a brief hiatus, and this episode of the FX drama will be dedicated to the big baddie of the season, the Ten Commandments Killer. The pivotal episode will finally reveal the murderer that John Lowe (Wes Bentley) has been chasing all season.

Fans will not have to wait long for the killer's identity to be revealed, according to Entertainment Weekly. The person responsible for all the deaths at the Hotel Cortez will be revealed within the first 10 minutes of the show. Much of the episode will unfold through a series of flashbacks that reveal how the killer came to be at the hotel as well as the person's intentions. The killer also has a secret trophy room that is full, but not with the traditional sports kind of trophies.

It will also be revealed that the Ten Commandments Killer had an accomplice all along, according to TV Line. The accomplice is even better at getting away with murder than the boss and, by the end of the season, two more will die. One of the deaths will come by the end of tonight's episode and will be one of the major characters that has been on the show all season.

"American Horror Story: Hotel" returns tonight at 10 p.m. ET on FX.
