In Love with a Fictional Creation?

  i may be wrong about this, but it seems female fans often fall in love with Sherlock Holmes & Lord Peter Wimsey, but not with Hercule Poirot or Nero Wolfe.

  Of course, Lord Peter's title and wealth are a plus, and Nero Wolfe's irascibility is a negative, but Wolfe is wealthy and Holmes is irascible, so that can't cover it.
   i think the key
is that Wolfe and Poirot are so self- assured.
  No, self-assured doesn't cover it.
 They seem complete in themselves. They don't need anyone else, but

Holmes and His Lordship project kind of a lost & broken little boy aspect.

• Lost Boy: you want to be the one to find him, and for him to find his home in you.
• Broken Man: Well, in real life a fixer-upper guy could be a bad bargain, but, really, it would be cool to be the one to make Sherlock want to give up his cocaine and Lord Peter forget the trauma of WWI in your love. 
• Taming the horse that no one else can get near: love and power, not mention savvy insight..

Husband scale: Poirot best, then Lord Peter, then Wolfe, and Holmes would be the worst.

Seems desirable husband does not equal treats you best.

i found this after typing my draft of this, but essentially this writer looks at Holmes as i do:
