pursued by Gwen. Investigations by a woman named Holly (voice of Eliza Dushku) establish that Jack was kidnapped by the Three Families so they could acquire entire vats of his blood, which she destroys. Audio drama In addition to the paperback novels, Jack also appears in Torchwood audio books, the first four being Hidden written by Steven Savile and narrated by Naoko Mori, Everyone Says Hello written by Dan Abnett and narrated by Burn Gorman, released February 2008, In the Shadows by Joseph Lidster and narrated by Eve Myles, released September 2008, and The Sin Eaters written by Brian Minchin and narrated by Gareth David-Lloyd, released September 2008. Joseph Lidster also wrote a BBC Radio 4 Torchwood drama, "Lost Souls" which aired in Summer 2008 as an Afternoon Play featuring the voices of John Barrowman, Eve Myles, Gareth David-Lloyd and Freema Agyeman. Set after the events of the 2008 series, Jack and his team make their first international adventure to CERN in Geneva, as part of Radio 4's special celebration of the Large Hadron Collider being switched on. The special radio episode's plot focuses on the Large Hadron Collider's activation and the doomsday scenario some predicted it might incite, as well as the team's mourning of Toshiko and Owen's recent deaths. Between 1 and 3 July, Radio 4 aired three further audio dramas in The Afternoon Play slot, bridging the gap between Series 2 and 3. "Golden Age" introduced Jack's ex-lover Duchess Eleanor (Jasmine Hyde), the leader of Torchwood India, which Jack closed down in 1924. "The Dead Line" features another ex-girlfriend of Jack's, Stella Courtney (Doña Croll). 2011 audio drama series The Lost Files was released to tie in with Miracle Day. "The Devil and Miss Carew" and "Submission" are set in the same period as the previous audio dramas. "House of the Dead", however, reveals itself in its final act to be set six months after Ianto's death; Jack visited the House of the Dead to make contact with Ianto, who is unaware that he is dead. Jack and Ianto say a final goodbye and tell each other they love one another for the first time. Jack attempts to return to the land of the living alongside Ianto, but Ianto stays behind to close the Cardiff spacetime rift forever with Jack's device. In 2015, BBC Worldwide granted a licence for Big Finish Productions to produce Torchwood audio plays.
