Ever watched Cold Case? It used to be on Mondays but now it's on Tuesdays @ 10am on Channel 5. It's like CSI with a twist and I quite like it better than other serials, even better than CSI.
Every episode is about a case that went cold, a murder unsolved. It could be 50 years ago or it could be just last year. Documents yellowed with years gone by and youths grew old. But someday, somehow, some little clue surfaced, a scrap of paper, a little note, and the case is re-opened.
The show is less about forensic investigation but more about interviews with the people involved. I like the part where each person flashback to the time of the crime and recounted their perspective of what happened. Of course, some of them would be lying because of some hidden agenda related to the crime, a little like the cross between Cluedo and Akira Kurosawa's Rashomon. The detectives on the case then slowly piece things together, gathering more witnesses and testimonies along the way before eventually solving the case. Throughout the interviews, the camera shows each person alternatively as at the time of the crime and at the time of the interview.
What I like most about the show is that when each case is solved, Detective Lily Rush will look over her shoulder. She always imagines seeing the victims standing nearby, giving her a look of gratitude and approval before turning around and fading away.
