It turns out Professor Rachel Jensen never did get time to write those memoirs!

Counter-Measures continues the adventures of Professor Rachel Jensen (Pamela Salem), Group Captain Ian Gilmore (Simon Williams) and Allison Williams (Karen Gledhill) - now working for Sir Toby Kinsella (Hugh Ross) - as they battle threats to England during the 1960s.

Next year will be 30 years since the Doctor Who story Remembrance of the Daleks was broadcast - starring Sylvester McCoy and Sophie Aldred, and the original team Pamela Salem, Simon Williams and Karen Gledhill.
