Is there a code? Perhaps, but these people certainly have not discovered it.
Shown recently as part of an ITV3 season of films to do with Agatha Christie I really shouldn't be surprised by the quality of this documentary because this is the same channel that has given us the mostly terrible Marple series of films. The title is the first clue that this is a desperately populist film that is more about trying to liven it up than it is do a good job as a documentary.
