Agree on the Double Shock. I never understood that either. In fact, it forces the lawyer to have to explain what really happened and just points more guilt their way. The lawyer had no motive, so his story would likely have been believed.

I think with Double Shock the brothers were getting worried they were going to get implicated, so they tried to shift the entire blame off to the lawyer.

YES, this plot makes no sense at all. And what about the timing ... when did Uncle Leon and Freddy's wife start their affair? There was no financial element until Freddy happened to hit the lottery?
