Okay, so I found I had 'The Half Dead City' download hanging around in my Big Finish account (I assume it was an impulse buy during the Christmas sale that I promptly forgot about), listened to about half of it and... just bought the second series bundle.
I can't quite keep track of all the characters and am really not quite sure what is going on, but it's addictive!
Glad you went for the 2nd series as well.You will really enjoy it. Its a bargain purchase!!!
You were very persuasive, and I think this is going to be a great range to start following.
Thank you for your timely push in the right direction!
