Over the past month I've been working on an outline for my science fiction novel and I've run into a snag. The plot, in a nutshell, is that an army veteran is sent back in time by a "evil" company that has secretly developed a time machine, his mission is to attempt a rescue on an agent of the company who was sent back to manipulate the past for some sort of financial gain. The problem im having is that i cant think of what the agent's mission could have been. It should be something simple like an assasination that would net a significantly larger profit than say going back and buying a bunch of lotto tickets, also the time period is prior to the renaissance. Any help would greatly be appreciated.
