When her husband is murdered, a headstrong businesswoman must turn to a tortured past and deadly skills to hunt down the killer and save her own life.

Agree with Foxtrot25 and Nir Shelter.? What skill set does "her tortured past"? give her to identify and apprehend the murderer?? And they have offered examples of slipping that information in without bloating the logline.

Agreed with Karel and Foxtrot25.

I would go as far as describing adding detail to her past this will eliminate the need to specify the skills, i.e:

After her husband is murdered, a former spy gone businesswoman must hunt down the killer to save her own life.

"...Hunt down..." implies to kill him, or her, and by specifying her as a former spy it's made clear that she can do it.
