I have an idea for a story and as I plot driver I think it would work to have flashbacks. The story will focus on a single character searching for clues to an event that will lead him to understand his present situation. What techniques are there for using flashbacks? How would I let the reader know that while they are reading we have made a jump into a flashback? I would like to construct the flashbacks as short stories in and basically insert them into the larger narrative. I'm thinking of tell the story from the first person. But I'm toying with the idea of making the flashbacks unique to the characters point of view the main character interacts with. I don't know if that switch along with the flash backs will make it too confusing.
