I don't understand, sorry.
So, more suspects make it automatically a better mystery or if you don't have a legion of suspects, it's a half-washed attempt at a mystery? Why? I have no issue with readers guessing who dunnit and or guess right from a limited pool of suspects - they still need to read to the end to confirm their suspicion and to find out WHY this is all happening.
Why does it have to be hard/impossible/so complicated that they have no clue right up to the end? That is not avoiding the mystery, that is trying to make sure the mystery does not become the prime storyline, drowning the Romance with a capital R. This whole thing of trying to make it impossible to guess or be so subtle with any clues that readers don't even know it's a clue is not what I'm trying to achieve, primarily because I don't want the mystery to overshadow the Romance, not because I don't care or it's too hard to even try. And I have no problem with writers that try to that either, it's just not what I'm going for, because Romance.
I have always said, this is first and foremost a Romance. And I'm still saying, this is first and foremost a Romance. It is not a mystery with a love story component. The mystery is the inciting incident and that is all there is to it. But neither does it mean I have a brilliant excuse to do a half-washed job of the mystery. The mystery I have presented in the first chapter of NS will be resolved in NS, but more importantly, not at the expense of the Romance I have presented in the first chapter.
As a side-note - Right at the end there will be a hint at a bigger mystery which will lead into book 2. And right at the end of book 2, there will be a hint that the bigger mystery is even bigger and goes even further back than originally thought, leading into book 3. I can also say, I'm not writing a series. Each book in the end will be written such that each can be read independently. *Yeap, I like pain!* So far, there is nothing in NS to make anyone think otherwise - that is all coming from replies to reviews and comments I've made in forums ...
I'm also starting to suspect you have Black John, Matthew (Earl of Norwood) and Anthony (Anthony Aiden, Baron Aiden) all mixed up. The last chapter you reviewed, Matthew was training young men, Black John and Anthony/Aiden were sparring. Matthew was enjoying the show. I have no idea what you are saying when you say here:
A sparring match isn't a battle, but M gets portrayed as tougher if he beats BJ. BJ's reaction gives clues on how persistent he is, how much hurt he is willing to take, and how far he is willing to go. (Ergo…leading to whether he is a suspect or not).
BJ can wait for his turn to shine. Matthew is just about to enter another situation to prove his worth in a fight (the first one was the raid on A's tower) and it's not the last opportunity either. First, BJ and A will match each other, and then M will and will be portrayed, hopefully, as tough enough.
I also don't understand this:
I never have any doubt that M is going to win his fights. There has to be risk.
This would be true if BJ or A was the bad guy. So far, IMO, the bad guy is making M's life pretty miserable and anything I would call easy or 'no risk'. M isn't fighting BJ or A .... So do you really think, if you think back in terms of the mystery bad guy, that there's no risk or it's too easy for M?
