Six years previously Doyle was a policeman at London's Docklands and he was involved in a shoot-out in which there were fatalities. Bill Haydon was arrested and charged and sent to prison. Now his daughter Jill has come to see Doyle, claiming that she has fresh evidence to exonerate her father and asks that the case be re-opened. Doyle gets close to her. Maybe too close to be objective. . . Written by don @ minifie-1

Did You Know?


When Bodie and Doyle eventually locate Haydon's car in a second-hand car showroom, they discover that the radio is just a false front with knobs attached to a drawer where Haydon's gun was hidden. It is highly unlikely that the car would have been used by its other owners in the intervening six years without someone trying the radio and discovering that it was a dummy. See more »

THE PROFESSIONALS – When the Heat Cools - 1978

This is episode nine of the 1977 to 1983, UK, action-crime series, THE PROFESSIONALS. Gordon Jackson is in charge of CI-5, a group of men drawn from the SAS, Police and other law enforcement agencies. Their mandate is to stop acts of terrorism and threats against the UK.

Current CI-5 agent and former Policeman Martin Shaw is approached by Lalla Ward. She says she has new evidence that will prove her father, Peter Hughes innocent of a murder conviction. Shaw wants nothing to do with the matter since it had been another Policeman who was killed.

After mulling matters over in his head, Shaw decides to look into matter again. He needs to give himself piece of mind over the friend's death. He takes Miss Ward's evidence and backtracks through to the various witnesses etc. He finds items that had been missed on the original case.

The further he digs the more it looks like maybe he helped convict an innocent man. Fellow CI-5 agent Lewis Collins lends a hand in the new investigation. Lewis thinks there is something fishy about the new evidence. Nothing concrete, but just enough for Collins to look a bit deeper.

Needless to say it is all a well thought out scam by Hughes and the daughter, Ward. Ward has altered court documents and paid people to put them in the proper files. She had even bumped off a key witness in the case. Hughes gets extra time and the daughter gets sent up as well.
