Lost Souls (audio story)

Lost Souls is an original BBC Radio 4 audio play written by Joseph Lidster. It aired on 10 September 2008 in the Afternoon Play slot as part of Radio 4's Big Bang Day. It celebrated the switching on of CERN's Large Hadron Collider that day. Andrew Marr introduced the audio play live from CERN. An MP3 version of the audio play was made available for seven days after broadcast. It was released on CD 18 September 2008.

Publisher's summary
When scientists start to disappear prior to the activation of the Large Hadron Collider at CERN, Switzerland, Dr. Martha Jones of UNIT asks her friends at Torchwood 3, still grieving over the recent death of two colleagues, to investigate.

Cast

 * Captain Jack Harkness - John Barrowman
 * Gwen Cooper - Eve Myles
 * Ianto Jones - Gareth David-Lloyd
 * Martha Jones - Freema Agyeman

Continuity

 * When greeting Martha, Jack welcomes her with the words "voice of a nightingale", the phrase he used on her arrival in the Torchwood episode Reset and again when she telephoned him in DW: The Stolen Earth.
 * Julia Swales was first seen working alongside Martha in DW: Smith and Jones.
 * When Jack mentions Martha's fiance, he is presumably referring to Thomas Milligan, rather than Mickey Smith. The last time Martha saw the team was at Tosh and Owen's funeral, before the Medusa Cascade incident occurred, which is when she met Mickey Smith.
 * Evidently this isn't the first time that CERN was involved with creating a black hole, as K9 Mark IV was tasked with fixing a black hole created by an earlier experiment in Switzerland. (SJA: Invasion of the Bane)

Download and CD release
Lost Souls was released by BBC Audio in both CD and MP3 download formats on 18 September 2008, only a week after broadcast (ISBN 978-1-4056-8944-1). Straight after initial broadcast, for one week only, internet users could download the radio serial free from the BBC website. The CD also includes the BBC Radio Wales feature Torchwood: All Access. Presented by Julian Carey and aired to coincide with the debut of Series 2, this is a 25-minute documentary on the Welsh aspects of the program, featuring interviews with Russell T Davies, Eve Myles, Gareth David-Lloyd, Kai Owen and behind-the-scenes personnel. The mastering of the track contains an error that results in several minutes of discussion regarding the Hub set and its construction being repeated.

Lost Souls, Asylum, Golden Age and The Dead Line were released, both individually, and together as a four-disc collected box set, entitled The Radio Adventures.
