I very much enjoyed Tony Lee's Rat Trap. Lee has written some excellent Who comic strips, but I think this may have been his first audio script, and I hope it will not be his last. It's a claustrophobic tale of Five, Nyssa, Tegan and Turlough exploring tunnels under an English fortress, and encountering two rival groups of humans and for added excitement some superevolved intelligent telepathic rats. The plot is decent enough but what really makes the audio is the sound design, which superbly conveys the inhumanity of the rats (brilliantly brought to life by former Davros Terry Molloy) without making them incomprehensible. A great example of what audios can do. ( )
