I must admit that "who did it" murder mysteries are not my cup of tea and I'm therefore not really the target audience for this type of show. However, Paul Abbot's involvement and the political thriller element attracted me to the show. It looks great and the acting is good. However, a lot of the action simply appears to be there to fill time and the show is probably 3 hours too long. The final twist seems illogical as it is not supported by the action which took place during the previous 5 hours and 55 minutes. Also the mystery is solved due to a slip of the tongue rather than the investigative work during the previous 5 episodes. If you buy the DVD please do not read the scene index inside the box as it gives away the ending.
