Dons the rubber suit

Paul Collins in Slate:

Creaky as his apparatus now looks, [Wycliffe] Hill was onto something: Other plot wizards followed, including Plotto, the insanely complex 1928 creation of pulp novelist William Wallace Cook. (His pseudonymous memoir isn't titled The Fiction Factory for nothing: Cook once bashed out 54 "nickel novels" in a single year.) Rare and comically user-unfriendly, Plotto required its own accompanying instruction booklet—which, invariably lost or disintegrated in the intervening eight decades, leaves modern discoverers of the unaccompanied volume bewildered. Plotto resembles a thesaurus filled with cryptic codings and narrative fragments:
