Have you heard of Plotto? Neither had I, up until this morning. It’s a text from 1894 by Georges Polti, which creates a structural system for creating story plots. It’s quite extraordinary, taking 36 basic plots through a staggering 1462 plot permutations. Below is one example.

Plotto is being reissued by Tin House. Fun for the whole family (if your family is full of aspiring authors, or plot geeks).
