The terribly polite psychopath

" I'm terribly sorry. Hope that didn't hurt." cried Tim as he pulled the pickaxe out of the freshly penetrated skull of his new boss.
As a medical resident, Tim was at the bottom of the food chain in the medical community. And his seniors were forever pissing him off. Its not that he had anything against them personally. He hated it when people didn't just listen to him. He had a frail voice and his small frame.Usually by the time people pay attention to him,they're usually tied up and losing blood at a rather alarming velocity.
Tim was a genius.He knew how to cover his tracks.49 bodies dismembered beyond recognition in about 500 small plastic bags at the bottom of the ocean stood testament to that.
"Look at all this blood. My god what a mess. Don't worry doctor Martinez, ill get you cleaned up right away".
