Watching, and Waiting.

Prologue.

The killer watched, and waited. He observed the young man as he went about his business. He was a federal agent with the NCIS. His name was Tony Dinozzo. This much he knew. He didn't know why he felt such a strong urge to kill this young man. But he knew he would. He watched, and waited, biding his time. It would come. Oh, yes, it would come.

The killer picked up his gun. It was a deadly looking rifle. Military issue, untraceable. He saw Dinozzo come out of the NCIS building alone, munching on a sandwich. He brought his rifle up to aim.

Then his view of Dinozzo was obscured by a beautiful young lady approaching his target. Well, he thought, no reason not to play games with him. He brought the gun to bear in the center of the lady's back, and fired.
