The BlackList

 Elizabeth is FBI agent - smart, brave and good looking. She has a loving husband, planning to a adapt a child and moves to a new department in FBI. An extra ordinary criminal Reddington who was never caught but is wanted in many cases, wants to help FBI to catch a "blacklist" of other criminals - but he is willing to interact only with Elizabeth.

He has answer many crimes and seems to know every who and who in the criminal circle. He promptly helps FBI catch many of them. 

But he keeps telling Lizzy - as he calls her - that her husband is plotting against her. But how ridiculous? Tom - the husband is a simple, sweet school teacher, who is accommodating of  Elizabeth's super busy schedule and her absence in most social functions. 

So Red keeps helping FBI catch many criminals- even those whose existence is unknown to FBI. But  his methods are questionable.

Ok. You can watch one or two seasons if you’re into crime thrillers
