A 1975 fairly good period drama. At first I was disappointed in the quality of the forensics at the crime scenes then I remember it was '75 so I'll excuse the producers. Disconcerting to see such discourteousness toward the police by the populace. More troubling is the annoying assistant detective (DS) to Dalgliesh, unrealistically annoying. Poor character for the position, thus not too believable. The other newly arrived assistant female DS, filling the gender & ethnic requirements at once, is just the opposite in personality; also not too believable.
