The End of the Story!

My attempt at writing a short story:

He was hiding behind the rock. It was a big rock and it shielded him from the bullets flying his way. He felt safe for the moment but little did he realize that one of his assassins had circled around and above him. He didn't even hear the gunshot.

All I need is a beginning and a middle (with some love interest - plus a dog, guitar, mom and a train) and I think I have a million book seller. Anyone want to help me out here?
