Hudson Box Office (HBO) - DCI Banks

Peter Robinson's DCI Banks series is now available on DVD. The tenacious and stubborn DCI Alan Banks unravels disturbing murder mysteries aided by his feisty and ambitious young assistant, DS Annie Cabbot.
Unlike many police procedurals, that focus on the  idiosyncrasies on the main character, this effort is true to Robinson's vision of competent police work resolving complex crimes.
The library has the first two seasons. For more information link here.
