Walter
Episode 1 (1x1)
: 08, 2014
In the pilot episode, the appointment of a new Chief Superintendent - Addison (young, fast-tracked and therefore not entirely street-wise) - coincides with the dramatic death of a serving detective, Dick Romney. Walter is tasked with taking over the dead officer's cases and trying to track down an undercover officer, apparently lost and alone deep within a hardened drugs gang.
