With John Gregson's narration on the main US opening titles of this episode, follow by the powerful scene where Alfie Bass slashes a newspaper poster advert of a visit by The West German President, the viewer knows that they will be for an hour of a political drama, more than a murder mystery.
This episode is about one man's continuous hatred and bitterness towards Germany, because of his stuffing at the hands of The Nazis during The Second World War.
When he learns that the West German President is coming to London on a state visit, he decides to take the law into his own hands, by planting a bomb near where the state visit takes place.
What I like about this episode is the strong use of human psychology, within the persona of all the characters, whether it is Commander Gideon or the ordinary Police Constable on the beat.
It makes good use of the location work which takes place in the city of London. Backed up by good stock footage and reasonable back projection.
The interplay between John Gregson and Gerald Harper is very good. Mr Harper's performance as a young but arrogant and inexperienced Deputy Police Commander is excellent. He is a career man who's marriage is at rock bottom.
The actor who dominates this story is Alfie Bass as the bitter old man who wants to take out his revenge on The West German President.
Has with any episode of this television programme, the makers of this show, use a lot of John Creasey's writing to good effect.
This episode was based on 'Gideon's March' by John Creasey.
