The lovely Brooke is the young wife, estranged from a very wealthy (9 figures) husband, being divorced, but with the dreaded "pre-nup" precluding her gaining a lot of loot upon parting.
Hubby is murdered, her best friend (a gay! man) is incarcerated as her lover/murderer by the witless cops, and she is under surveillance/suspicion, also.
Enter a swarthy stranger - a man with a greater genius for computers and electronics at a level to make Bill Gates seem average - who wants $10-mil from the inheritance she can gain versus zilch if he incriminates her further. This guy has talents which, if hired by the CIA, could effect a solution to all Mideast problems, and with respect to terrorists, in perhaps a month or less.
Anyway, Brooke learns this guy has done the same thing previously - murdering rich guys with young wives, little or no family, and has shaken them down like he's attempting with her.
Along the way, for example, when she's approaching a woman in another city (she travels extensively on her mission), the cops there alert those at home. The detective from her home base travels there, and in company with a local tec, refers to Brooke as "One slick broad!" Actually, he may have said "clever broad;" but I laughed so hard, and then later wasn't certain which was the adjective used..
The "villain" is one interesting piece of work, who appears everywhere (as a friend's grandfather used to say, "like horse****), and whose fore-mentioned surveillance capabilities seem almost miraculous. He provides a synopsis of his family history and motivation to one intended victim. It's positively amusing.
The cops (or rather, one of them) finally begin to get the thought that someone other than Brooke might be perpetrating the events, but not until the last 1/6 or so of the presentation.
Again, interesting and entertaining, but for reasons different from what the creators intended.
