First of the trilogy of BBC Radio 4 plays released in 2009 as a bridge between Series 2 and Children of Earth. I missed this on initial broadcast, and didn’t get around to listening to it until my recent purchase of the CD set. This is pure quill Torchwood — something (or as in this case someone) falls through the rift, and Torchwood has to deal with it. There’s a detailed plot summary on Wikipedia. Good story with some interesting exploration of the Torchwood universe, and mostly well-acted. PC Andy gets a good role.
