Okay Im trying to remember a film I watched as a kid, I can only remember the plot.
Might be a TV drama
A child killed themselves because of a bully, when the parents are older the mother dies and the bully now grown up was accused for the murder of the mother. In the end it was revealed to the dad that his wife killed herself and framed the bully for justice for their dead child. The father then contemplates handing the letter his wife wrote to him before she killed herself explaining everything to the police if the bully seemed sorry. He didn’t so the father burned the letter in the end.
And it’s a British film.
Any help would be greatly appreciated
