The Silent Speaker is a Nero Wolfe detective novel by Rex Stout, first published by the Viking Press in 1946. It was published just after World War II, and key plot elements reflect the lingering effects of the war: housing shortages and restrictions on consumer goods, including government regulation of prices, featuring the conflict between a federal price regulatory body and a national business association, paralleling the conflicts between the Office of Price Administration and the U.S. Chamber of Commerce and the National Association of Manufacturers.

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.
