The Bill: Secret History (Part 2)

Bobby Henshaw, the suspect in the attack on Banksy's wife Naomi, is beaten up. At the hospital Bobby claims that whoever attacked him had been paid by Alistair Finch, the man who ran over and killed his younger brother Michael. The officers discover that Bobby's mother Judy and Alistair were having an affair and Michael had found out. Alistair was worried about the impact it would have on his reputation - and Judy now believes that Michael's death was no accident.
