'What About Justice' (tx. ITV 18/6/1969)
Written by Edmund Ward, directed by John Frankau

Tony, son of powerful Leeds industrialist Charles Arkwright, is arrested along with his business partner John Smith on various conspiracy charges, including money laundering. Charles Arkwright goes to his commercial solicitor Castleton, who recommends the lawyer David Main as the best man to help Tony, who claims to be innocent.

In London, George Wilkinson asks for Main's help after being dismissed from the Post Office after stealing two registered letters. Main is initially uninterested in the case, but when he learns that Wilkinson was in despair and in dire financial straights trying to support his ex-wife and child as well as his new partner and their baby, he decides to defend him. Meanwhile, Main turns down Arkwright's proposal when his son admits his guilt. Arkwright threatens to take his business away from Castleton's firm unless Main agrees to take on Tony's defence. Main finally relents when Arkwirght lends him the money to buy in to Castleton's practice and become an equal partner.

David reprimands his trainee solicitor Peter, an ex-barrister trying to rebuild his career, for not taking his job seriously enough. Main gets Peter to engage the celebrated barrister Sir Ernest Lang and asks Arkwright to exert his influence over the rich and powerful men in Leeds to get them to appear as character witnesses at Tony's trial. His plan is to blame everything on John Smith, who has several previous convictions, and say that he led Tony astray. Smith's case worsens when he is arrested after trying to leave the country on a false passport.

Main has a strained meeting with his wife, who is increasingly bitter about how little time he spends with her and the children. He insists that with Arkwright's help he can now double his annual turnover and that he simply can't afford to let this opportunity go.

On the day of Tony's trial, Main decides to defend Wilkinson himself, at the request of his secretary, who has taken a special interest in the case, especially now that the baby has died. Main's plea for mercy succeeds and Wilkinson is given a suspended sentence. Main arrives in Leeds just in time to see that his strategy has worked: Smith goes to jail for 12 years, while Tony Arkwright is sentenced to just over a year. Main returns to London and finds that his wife has left him and changed the locks to their house.
