A new trailer released for season three of Showtime's Penny Dreadful teases that we haven't yet seen real evil on the series.

The trailer hints that season three will see the show's characters facing an evil worse than anything they've come across so far. Considering the evil that pervaded both season one and season two, the third season hopes to raise the bar when it comes to bad guys.

It seems that Vanessa Ives (Eva Green) still suffers from the curse that lives inside of her: in the trailer, she speaks to the men who care for her: Sir Malcolm Murray (Timothy Dalton), who wants to save her soul, and Ethan Chandler (Josh Hartnett) who wants her body, as well as her heart. But as seen in previous seasons, Vanessa's soul belongs to something else, something dark and scary.

Green earned a Golden Globe nomination for her role as Vanessa in the second season of Penny Dreadful. She didn't win, but her portrayal of the constantly haunted lead on the series left an indelible mark on viewers.

Something this trailer also hints at is the return of Ethan to London: at the end of season two, Scotland Yard extradited him back to the U.S. after admitting that he was responsible for the grisly murders at Mariners' Inn, murders he committed as a werewolf.

Season three also deals more with vampires, similar to the series' first season. A photo posted to the series' official Instagram account shows a group of actors as vampires hanging around the show's set. That Instagram account also teased a location shoot in Chinatown.

Patti LuPone returns this season, too, although she'll take on a different role from her previous one as the Cut-Wife. Instead, she'll appear as Dr. Seward, a therapist intent upon helping Vanessa. If that name sounds familiar, Dr. John Seward is a character in Bram Stoker's Dracula, one of Lucy's suitors who went on to become a vampire hunter. Of course, that story has already run its course on Penny Dreadful, so the only connection between the two characters is possibly their last names.

Showtime cast Shazad Latif for season three as Dr. Jekyll. Of course, that's just one more iconic horror legend that the series will bring to life (we've already seen Frankenstein and his monster, Dracula and Dorian Gray).

Showtime announced the official premiere date for the series' return to the network. Fans of the horror series can tune in on May 1, when the first of nine episodes will air.
