Which of these ideas for a BM/WW novel sounds the most interesting?

I'm think of writing a novel with with a BM/WW relationship as a part of the story but not the main theme, at least for one of them, if you get what I'm saying. I have a few genres and ideas in mind and have thought up some good ideas. I came up with these ideas because they are ones that I normally don't see when it comes to books with that this kind of relationship and here they are.

Novel idea 1: A crime/femme fatale thriller about a BM lawyer who becomes sexually involved with the White wife one of the major partners of his law firm and when her husband is mysteriously killed he begins to suspect that she's involved when he discovers how dangerous she truly is.

Novel idea 2: A crime thriller about a WW police detective and BM bounty hunter who are both forced to work together and trust each other, falling in love in the process, when an major crime organization sends hitmen to kill them. This is after they both discover various cirminals they have arrested and apprehended are connected to said organization and want them dead because they vital information that could shut them down for good.

Novel idea 3: A romantic comedy/social novel about a May/December relationship where young successful BM (late 20s) starts a relationship with an older divorced WW (40s). After both having doubts about each other they agree to meet and go on a date only to find out they more in common they ever though possible and fall in love. Despite them their loving relationship, they still have to deal with negative stereotypes, prejudices, racism, classism and even ageism from mostly from her family and social circle, while he himself has to deal jokes and ridicule from his family and friends.

Like I said, these are just ideas and brainstorming for now. Let me know which ones you'd like to as a novel, If you like them that is.

 

I like #2 best! When I have gathered my thoughts I'll be back with more to say

 

Thanks for the feedback.

 

#3 sounds interesting

 

Thanks for the feedback. That idea has so many dimensions to it and I've always wanted to experiment with social theme writing.

 

These all sound fun but option 2 works best for me.
