As the French, I am enemies with Milan, and I recently noticed that Marseille is a red face, when it has always been green. I suspected that Milan had put a Spy there, so I stationed one of my own in Marseille. Sure enough, there was a Milanese Spy, making the city unhappy. He has been there a while now, and I can see him at the end of every turn. I also put an assasin in Marseille, with the hopes that he would be able to kill him, but no such luck yet. How do I end the life of this wretched filth of a diseased vermin who is sliming his troublesome way through my city???
