How To Sell An Unusual Or Complicated Story To A Literary Agent In Only Three Chapters

How can I sell an unusual or complicated story to an agent in only three chapters?

If a writer has got an unusual or complicated story then it's very important that the synopsis should set out what is unusual or complicated about it. Synopses are a very important part of the package that need to be sent to an agent. But synopses must not be overly long and overcomplicated in themselves. They must be simple accounts, straightforward accounts, of what the author has set out to do.
