Two Serial Killers, a Wedding and a Funeral — Marcus Freestone

It turns out that becoming a serial killer is more difficult than I'd expected. All these years of studying the 'greats', honing my plans, and I still almost got caught first time out. I need the magic number four to become a 'proper' serial killer and I'm getting impatient; there will not be a gap of a year between numbers two and three. I'm thinking more like days, to get the police and the media properly interested. I know that I'm going to be killing people but this is the only way I can think of getting the message across. Surely it's worth sacrificing a few lives to potentially save many more and change the world for the better? Is it immoral to kill a few rats in order to find a cure for cancer? Of course not, so how can it be immoral to take a few insignificant lives in order to cure the moral cancer that is killing the world?
