Penny Dreadful returns with 10 episodes and finds Vanessa Ives (Eva Green) and Ethan Chandler (Josh Hartnett) forming a deeper bond as the group - including Sir Malcolm (Timothy Dalton), Dr. Frankenstein (Harry Treadaway) and Sembene (Danny Sapani) - unite to banish the evil forces that threaten to destroy them.
Meanwhile, Dorian Gray (Reeve Carney), the Creature (Rory Kinnear) and Brona (Billie Piper) are all waging battles of their own. Patti LuPone guest stars as a mysterious character of great importance in Vanessa's past.
Helen McCrory returns as Evelyn Poole (a.k.a. Madame Kali), the seductive spiritualist who poses a unique threat to the protagonists this season, along with Simon Russell Beale, who is back as eccentric Egyptologist Ferdinand Lyle.
Additional guest stars include Douglas Hodge as a Scotland Yard investigator; Sarah Greene as Poole's powerful daughter, Hecate; and Jonny Beauchamp as a man with a singular past.
