Third radio play set in between season 2 and Children of Earth. The mystery is interesting there are really no bad guys in this, just something that can't help itself. Nice Jack/Ianto in this. Ianto's monologue on the short time they have together is interesting, if not an omen of things to come. The team of Gwen and Rhys is pretty good. Again, Gwen is competent without being a miss know it all and Rhys is just plain fun.
