Audio Dramas
The BBC has aired several Torchwood radio dramas featuring the cast of the series.
To tie in to Radio 4's CERN themed day in 2008, a CERN-themed radio episode of Torchwood written by Joseph Lidster, entitled "Lost Souls", aired as the day's Afternoon Play on 10 September. This was the first Torchwood drama not to feature Burn Gorman and Naoko Mori. Three further episodes were commissioned due to the success of Lost Souls. Three more radio episodes were recorded in Los Angeles for transmission in July 2011.
All the dramas were set between Series 2 and 3, except "House of the Dead", occurring six months after Series 3.
