Ace should have just quietly and discreetly killed Lester
I know that Ace wasn't a killer but he sure didn't mind letting someone else get their hands dirty for him. It wouldn't have been too hard to arrange for Lester to go on a cruise somewhere.
If Lester ended up dead, then Ginger would always suspect Ace. But if Lester just vanished, like he just up and left Ginger behind, she may have gotten over it and become a better wife.
