Only a short while after the explosive ending of the fourth boxset, Big Finish are teasing the return of Counter Measures. Nothing much was mentioned at Big Finish Day 7 (apart from the UNIT overlap - see here), and I note the flyer has all the cast whereas the news item only has Sir Toby.

My guess is the whole team are alive and secreted away somewhere, though may not all appear in the new special. No word yet on writers, plot lines, cast… I’ll keep you posted.
