Tales From The File #3254; The Laughing Corpse

He was dead alright, and it looked like an open and shut case, but something was niggling me and wouldn't stop. I headed over to Hot Cawfee to clear my head. The coffee was hot, too hot for my liking, but it was strong and pretty soon the thing I was looking for hit me bang on my head. The corpse was laughing, why hadn't I seen it coming? I sank another Coffee and took a cab to my office, someone had to open a file on this case and I guess it had 'ME' written all over it.
