Nicola Walker

 ( 1970 Births ) 

She played the leading part of DI Susan Taylor in the ITV Network thriller serial Touching Evil in 1997, co-starring opposite Robson Green. She also appeared in its two sequel serials in 1998 and 1999.

In 2003, with the production team of Kudos Television looking to replace the character played by Jenny Agutter in Series 1 of Spooks, the part of Ruth Evershed was specially written for Walker from Series 2.

She returned in 2009 and continued until the series ended in 2011. Benji Wilson of The Daily Telegraph praised Walker's performance, stating: "an actress who has squeezed every drop out of TV’s greatest ever largely dumbstruck doormat for the best part of a decade. Her scenes with Peter Firth, another fine player, have become self-contained little bubbles of weltschmerz within every recent episode"."Spooks" was also titled and seen as "MI-5".

The Chenka character proved popular both with producers and listeners, and in February 2014 Walker returned to the role, this time as a foil for Paul McGann's Eighth Doctor in Dark Eyes 2. The character was sustained throughout Dark Eyes 3 and Dark Eyes 4, at the end of which it was revealed that Chenka was to continue as the Doctor's established travelling companion.
