For those of you who don't peruse the BBC's Press Office website:
The Torchwood radio plays, which will bridge the gap between the radio play 'Lost Souls' and the TV Season 3 story 'Children of Earth', will be airing from Wednesday 1 July - Friday 3 July at 2.15pm (for 45 minutes) on BBC Radio 4. (

And 'Children of Earth' will be airing on five consecutive nights, at an as-yet-unspecified time from July 4 - 10. (
