Plot It Yourself is a Nero Wolfe detective novel by Rex Stout, published by the Viking Press in 1959, and also collected in the omnibus volume Kings Full of Aces.

Nero Wolfe is a brilliant, obese and eccentric fictional armchair detective created in 1934 by American mystery writer Rex Stout. Wolfe was born in Montenegro and keeps his past murky. He lives in a luxurious brownstone on West 35th Street in New York City, and he is loath to leave his home for business or anything that would keep him from reading his books, tending his orchids, or eating the gourmet meals prepared by his chef, Fritz Brenner. Archie Goodwin, Wolfe's sharp-witted, dapper young confidential assistant with an eye for attractive women, narrates the cases and does the legwork for the detective genius.
