S03E07 — Father's Day

Nick arrests Blaketon's son Graham for mugging a suspected drug dealer. Graham tells the police he did it to stop him pushing drugs to the youngsters. Blaketon is horrified but insists that there's nothing he can do and that the law must take its course, to the annoyance of his ex-wife. Meanwhile, Greengrass delivers a letter to Betty Such from her late husband. It tells her that a key to his safety deposit box is in the pocket of his best suit, but he was buried in that. So Betty and her son go and rob his grave to retrieve the Key. Once they have the key they open the box which is full of money. They celebrate their good fortune and start spending the money in the pub, but Gina realises its forged and tells Nick. Betty realises the notes are all forged and she realises that her husband has set her up from beyond the grave.
