I am not the biggest fan of the "Special Branch" series from "Euston Films" but this episode is surprisingly good. A known fraudster is arrested at the beginning and after being taken to the station, Craven makes it clear what his real intentions are toward this fraudster. The latter has been kept under surveillance by Special Branch since his release from prison. The real reason for his being held, is because Craven wants to know what occurred 4 years previously when a well known business tycoon was imbezzling company funds that were supposed to be used to build a new city in Africa. The fraudster worked at the same firm and accidentally caught on to what this tycoon was doing. As a result, he began blackmailing him. All the details are revealed via lengthy interrogations and it makes for gripping viewing. The fraudster isn't exactly a hard case, he's rather vulnerable and fragile. Craven isn't satisfied that the blackmail was a one man job and begins pressing this man for the truth. There aren't any flashback scenes during the mention of the business tycoon in question but there isn't any need. The script is very descriptive and you can easily picture in your mind's eye, the setting of that of the company offices, the staff, the business tycoon. He is not portrayed as being a particularly sympathetic character, as he was a thief and rather sadistic in his business methods and the way he treated his staff. The only thing that disappointed me slightly, was that the ending left everything in mid air. Regardless, this is the one of the better episodes.
