1 Shakespeare: All right, I have this other throw away idea about a young writer who travels through time, getting inspiration for stories from history.
2 Shakespeare: He takes his grand-aunt, also a writer, with him, and she solves all these historical murder mysteries.
3 Shakespeare: She loops through time, watching the crimes over and over until she memorises all the details, then uses that knowledge to uncover historical evidence in the present day.
4 Mercutio: Sounds great! What do you call it?
4 Shakespeare: Murder, She Rote.

This plot idea is based on one of the real world William Shakespeare's more obscure plays.

Because as we all know, everything is based on Shakespeare.
