Merrin

The World War has come and gone. There is huge damage but real peace. Now the world is divided into three great empires, and the Emperors have gathered to choose the new World President and acknowledge the old one is retiring. There isn't a wide selection for the job, and the pool gets quickly smaller as candicates are deleted from selection, not by vote but by assassination. Who is left to take up the reins, for the biggest job on the planet?
Our hero is a mild mannered man but some believe that since he has the most to gain, it must be him that is behind the murders. How can he prove his innocence AND avoid becoming the next victim?
