UK television production—Thames Television. Thames picked up the series again in 1969 and produced 46 more episodes; unlike their ABC precursors all 46 remain safely in the archives, although 11 of these were still produced and broadcast in black and white. One other was made in colour (but broadcast in black and white) as a test of Thames's new colour equipment, which was first used for broadcasting from November 1969—two months after the fourth series of Public Eye finished its on-air run. ABC's audience research had shown that many viewers found the character of Marker as interesting as his cases. For this reason, the first Thames series is quite different in style from the other three, and was written entirely by Public Eye co-creator Roger Marshall. Commonly referred to as 'the Brighton series', the collection of seven episodes links together to tell the story of Marker's release from prison and his gradual rehabilitation into everyday life, culminating in him renting a new office and starting up again as an enquiry agent. This series also introduces regular characters such as Marker's probation officer Mr Hull and his landlady Mrs Mortimer — the first such characters in the series apart from Marker himself. The Brighton episodes The first episode of the fourth series, "Welcome to Brighton?" (broadcast 30 July 1969) starts with a custom title sequence giving a brief recap of Marker's offence and his prison career. The first shot is of Marker lying awake in bed with the judge's voice going through his head, passing sentence on him. It is about a year since the events of "Cross That Palm When We Come To It" and Marker has been transferred to an open prison before being released on parole to complete his sentence. He is determined not to fall into a life of crime, despite what his fellow prisoners tell him ("You've crossed over the line now, mate — you're not one of them, you're one of us!"). In the first half of the episode, Marker is released from prison and heads for Brighton where the parole system has arranged accommodation for him with a Mrs Mortimer (Pauline Delaney). Through an extensive location-shot sequence on the sea front at Brighton, the viewer experiences Marker's disorientation at a world which appears to have changed considerably since he was sent to prison. He immediately encounters the very same sort of people with whom
