I loved Silk but it was always silly. The finale surpassed itself.
Yes, where did Martha go? Unless she made a grab for the passing bus.
And I agree about the jacket. Evidence does turn up at the last minute but surely they'd need to examine the blood on it to find out whose it was rather than just saying it was the victim's.
Martha would insist on that, just like she'd ask for an adjournment to consult her client about it. I guess she'd also introduce the amazing last-minute appearance of damning evidence like the gun and the jacket and question where it had come from and whether it was all a set-up.
And people kept speechifying and making accusations in court and the judge rarely pulled them up on it. Does that really happen?
Also, I thought Billy did proposition Amy for sex. I thought he was doing it so he could prove to himself that he was still a man. I found that in keeping with his character. But then they changed it.
I also think that in a situation like that the chambers would reject Amy's application and stick with Billy whether they thought he'd done it or not.
