About 10 years ago I watched this murder mystery movie. It followed a cop investigating an attempted murder, and his prime suspect was the husband.
The husband was toying with the police, knowing they would not find evidence that would lead to a conviction. I think the police did get the case go to trial, but the husband was acquitted. Because he would not get sued again for the same thing, he opened up to the cop.
What he didn't count on was that the wife, who was still in the hospital died in the meantime, so using the confession, the cop brought the case to court once again, this time for murder.
One last detail I remember about this movie was that the husband had some sort of marble track.
I think around early 2000s.
Country of Origin:
This movie was definitely from the US.
