Writers Block

It was just another one of those nights Chris was sitting in the living room watching another reality TV program, one of about fifty that seem to be on constantly, and Mark was sitting at the computer trying to start his first ever novel. He had written short stories for years but never felt that he put together a whole novel.
He had been trying towrite thois particular Novel for nearly fourteen months now and had written somewhere close to twenty first chapters but as soon as he had introduced the main characters that was when it started to fall apart.
Mark was typing away at the keyboard, hoping this would be the night it would all fall into place.
He was starting the second chapter, after another new first one when "bing", he had mail. As soon as he had opened it the name staring out at him filled him with dread. He had thought it was just another one of those get rich quick schemes or cheap viagara from Canada, but this was not as mundane as that.
The name read Simon Smart, this was the serial killers name, the same one who was sent to the chair only yesterday, the same one whom he had based two of his short stories on, and the same one who had written to him and asked to meet with him before he was executed. Mark had never gone because he could not bear to be in the same room as someone who could torture his victims before killing them in such a grusome way that the press didn't even want to know how he had killed them.
Mark's finger hovered over the mouse button, wondering if he should open it or just delete it. What harm could a simple email do, but then again what if it was some kind of threat from someone who knew him and had been told about Mark from Simon himself, what could they want. No he was being stupid now, it was just an email if he opened it and there was anything he didn't like, click and the email was gone.
He decided he would open it, nothing ventured nothing gained eh.
click the email opened.
The first line made his blood curdle "I am watching you"
immediately he looked around the room and out through the window, nothing.
He went into the living room to see Chris, she had fallen asleep, nothing there.
He went back to the computer, the email still open, if the first line was bad it was nothing compared to what was to follow.
"I know what you have been doing, I know that it was you and not me that had killed those poor girls, I know that you are going to do it again, and when you do they will know that it was not me. They will know they have fried the wrong man, they will know it was you because of the letters i have left for the lawyers to read. They will be coming for you very soon now. You must pay with your life as did your victims. I will be watching you when you go to the chair, and i will be smiling and staring you right in the face. You will pay!!!"
Mark quickly spun round in his chair, his head was spinning, he didn't know what was going on. All his short stories had been about this serial killer and now he wasn't sure where his ideas had come from, could he have commited those crimes, no certainly not there was no way he could have done anything like that, could he?
The doorbell startled him, he called out to Chris to get the door, now covered in sweat panicking over nothing. The doorbell went again followed quickly be someone banging on the door. He called out to Chris once again, and once again no answer. He got up from the chair and went towards the front door looking in on the sleeping Chris again. She was not sleeping after all, her throat had been slashed. Mark quickly looked around the room for someone else, he looked at his hands and noticed the blood on them and on his shirt. how did that get there? the front door came crashing in as three police men charged in guns pointing straight at him. There were shouts and orders, he couldn't understand them, not thinking he turned towards the police then noticed he still had a knife in his hand. Finally he could make out what they were shouting "put the knife down" it was the last thing he heard apart from the loud bang that took half of his head clean off.
