It's not probably. 10 in reality but it is the final screen appearances by one of my favourites actresses, June Ritchie.
I watched the 3 episodes as an omnibus so I am not sure where each part ends.
In my opinion, it is the best story yet and a bit different to before as Wexford believes he has his man from the outset and nearly loses his job tracking him down.
A good twist in the tail in part 3.
I do feel that if made now then it would be tighter and less wordy and shown as a one of two hour show but a good watch even if it is just to save off our Ingrid Rothwell from A Kind Of Loving.
