With dreams of writing the next great American novel, a struggling author blackmails a middle-aged hitman for inspiration.

I really like it. One of the reasons I want to find out more is that it leaves the question of 'how' the goal will be achieved open.

What I was looking for in this briefest of brief logline was a tweetable # of characters that would entice the recipient into wanting MORE! :-)

I think this is great. Concise, clear, and compelling.

I guess I should have stipulated, this logline is meant to serve as a "twittersized" version: one that I can tweet out to an agent/manager/producer on a moment's notice!

It would be intriguing to know how this writer will blackmail a hitman because it seems like the hitman might as well just kill the writer and save all the bother. However that does make it an interesting story to find out. I do agree with Richiev in a way though as it doesn't really fit together and the hitman needs to be involved more than just for inspiration. What are the consequences if he doesn't write the next great American novel? What if they blackmail doesn't work? We need to know a little more about what drives the story.

This logline doesn't explain how blackmailing a hitman will lead to writing the next great American novel or what the consequences are.
