Jekyll and Hyde

The grandson of the infamous Dr. Jekyll returns to 1930s London from Ceylon after he experiences a disturbing transformation. As he delves into his family history, he begins to attract the attention of a secret society and a spy-master.

Having miraculously survived an attempt on his life, Robert follows the advice of Lily and Max and goes searching for answers at his grandfather's former home. His search leads him to an unexpected encounter at the Empire Hall.

Captain Dance's arrival in London excites the creatures in MIO's cells, including the ghastly Cutter. Searching for a cure, Robert takes some of the potions in his grandfather's lab. Garson tells Robert of a relative who may still be alive.

Garson discovers something about the curse of the Jekyll family that could hold the secret to saving Maggie's life. Dance sets his trap, tempting Robert with an offer of help - but Bulstrode disrupts their meeting.

Robert learns that there is a distant branch of his family, the Jezequiels, living in an isolated house in Suffolk and decides to visit. Robert is mistrustful of the widow Jezequiel. He must use his own powers to expose the family's secret.

Tormented by recent tragedies, Robert loses control of his transformations. Bulstrode reveals he has Ravi and enlists Robert to track down Spring-Heeled Jack.

Robert and Ravi go in search of Spring-Heeled Jack. Robert then faces a race against time when this Reaper takes control of Ravi.

Robert is unable to resist the temptation to track down the monster that is killing wealthy young men. When he corners the killer, she tells him two stunning pieces of news.

Fedora steals the incubus. Tenebrae attacks headquarters, stealing the Calyx, before arriving at Robert's house for a final, deadly showdown.
