actually shit just read further down you like action and mystery. okay, thats an easy one.

Suppose - a former British Secret Service agent living in an apartment in wartorn London during the Blitz is cast back in time to a particularly crucial point in history - a mission he failed years ago due to mistakes he made - mistakes he has had years since to reflect on. What if the past could be changed to change the future.

Setting - The Titanic in the hours before it hits the iceberg - the agent is back in time to the night he set out on the mission on the Titanic originally. His actions this time around can affect the future, preventing the events that lead up to World War II.

Characters

British Secret Service agent - The protagonist

Fellow Secret Service agent - The contact on the Titanic who provides the mission details and assists during the mission

German Colonel - Key antagonist. Travelling to America with the false cover of inspecting German embassies. However, he is in fact working with others to create a situation that in a few years will lead to World War I.

Young German - The Colonel's young protege. His true allegiances are a mystery. However later it is revealed he is a Russian agent carrying a notebook containing names of Bolsheviks that he knows intend to overthrow Tsar Nicholas II of Russia in a few short years. He needs to get the notebook to the Tsar's police to have these Bolshevik revolutionaries hunted down and killed (preventing the Russian Civil War and the formation of the Soviet Union)

Serbian art dealer - Travelling to America with paintings to sell in New York, One particular painting by a known German dictator is amongst the paintings, and is key to the plot

Serbian stowaway - A radical Serb that belongs to revolutionary group the Black Hand

you get the gist.

since this is a historical setting, should you use it, it is best to include a mix of historical figures from that time and place as well as fictional characters. if, like me, you have trouble creating character names for particular genres, use name generators on the internet. hope at least a bit of this helps you get started
