Starburst: Interview with Steve Lyons
Steve Lyons said in this interview:
Klein is different, she is very much my creation and I’m not really sure yet how I feel about her going her own way without me. On the one hand, it’s flattering that one of my characters has been picked up by other writers and her story continued. But then, I hear about major changes being made to Klein’s background, without my being involved or consulted, and that just feels wrong. I haven’t heard the latest Klein stories yet, I probably should.
This does not surprise me at all. The new Klein trilogy put out by Big Finish really messed up Klein's backstory and clashes massively with information in Colditz. I feel sorry for Lyons that his character has been treated this way, but on the other hand I feel relieved that such a great writer had nothing to do with it.
