[ WP ] Write a short murder mystery from the killer 's perspective

As I sat in my living room, thinking about recent happenings and drinking a cup of tea, I suddenly heard a knock on the front door. Interesting. I was n't expecting visitors. 
 
 Quietly, I opened the door. A small man dressed in a used up, grey trench coat stood there, with a notebook in his right hand. 
 
 `` Good afternoon, mr. Jackson,'' he said in a blubbering voice. `` I'm detective Perry Johns, I'm with the police department. Your neighbors informed me you might be able to give me some information on the… recent events?'' 
 
 `` I'm sorry, but what are these events you speak of, detective?'' 
 
 `` The… murder, mr. Jackson''. He seemed strangely nervous and insecure. `` I'm afraid ms. Pitt was killed last night.'' 
 
 `` Oh my… well, that is terrible. Just terrible. But I'm sorry, I do n't know anything of this killing. I went to bed early last night.'' 
 
 `` You did n't hear or see anything unusual?'' 
 
 He kept questioning me, hoping to get some sort of lead on the case. But I did n't give him anything. Nothing to help his searches. 
 He left unsatisfied, and said he wanted to search the crime scene further. 
 I closed the door behind him. 
 
 As I went back into my living room, a smile formed on my lips. A devilish grin, even. I sat down at the table once again. 
 
 `` I'll try searching the crime scene again.'' I thought about the last sentence I heard from the detective, and giggled. He was n't going to find anything, I was sure of it. 
 
 After all, I was very thorough with my cleaning.
