I want to ask about a movie I watched on TV in 2006 (but I guess it was produced in 1990s, I'm not sure). A wife hired a private investigating firm to prove that her husband was an adulterer. A woman from the firm seduced the man to frame his guilt as the adulterer... but somehow the husband developed real feeling for the woman after that meeting... The woman reciprocated his feeling, but was suspicious of him as he was related to some murders and attempted attacks on herself... Even the woman's friend was killed. However, it ultimately turned out that the wife was the real killer...
That's all I can remember.. there were some intimate scenes between the husband and the woman too...
I really want to watch this movie again, I've tried to search on Google but it always turned out to be "Chloe" (2009 movie), which is not true at all... Please help!
