When they finally gouge BBC gems from the vaults in DVD format, I hope they'll make this available too. The stories revolved around a little known police department that dealt with moribund cases that hadn't been solved. I can't remember too much more about it except that it wasn't particularly marvellous, but Tom Adams, the lead character, provided an unusual central focus for each of the relatively trite story lines. Adams went on the offensive in English Sunday newspapers about just how less-than-perfect some other TV detectives were, such as TV private eye Eddie Shoestring (Trevor Eve) and BBC's Target series Steve Hackett (Patrick Mower) (since Trevor Eve's wife (Sharon Maughan) was initially in the cast of "The Enigma Files", this was probably not too smart). Also memorable as a starting vehicle for the comedian Dougie Brown, who seemed more than adequate for the task.
