Well it would be amusing if he was as much an urban legend as the crypto-gynoids he tracked.

"There's a PI by the name of Carl Morris, he doesn't appear in any of our records except for his license. His client is Nozama Industries so we're stuck cooperating with him on this."

"That Morris guy, always looking at my shoes as if he expected my feet to burst out of them at any moment"

"Looked like he was haunted by something, later on he told us a hurricane ruined his life. Little did we know that it was on two feet and used to Carl's last name"

"The worst of it wasn't the lives transformed or the roles shattered. The real rub was it all could have been avoided had we just listened to that tweedy git Morris"

Perhaps Mr.Morris could be whatever we needed him to be in the story. If details conflict or make absolutely no sense that might just be conflicting 'accounts' of his very existence. There could be a thread of self-awareness also in that Mr.Morris would have in advantage in knowing the 'shticks' of the genre and how bestto avoid being smothered by them. Normal fiction folks wouldn't have that advantage. 

1. Freedom: Sure as much as you'd like, I'm just providing the concept, it's up to all of us to flesh it out however we'd like.

2. Sexual content: I'd say adhere to the rules of this site.  Story length: As much or as little as you're able to.

3. Carl Morris: Cowprobe described it better than I ever could've.

I hope this helps and I'm sure Pixie would love to encounter one of these men at just the right time...
