What is the author's style in The Doorbell Rang by Rex Stout?

Nero Wolfe loves language, and he chooses words carefully. When Nero Wolfe talks, he uses long words, but he also uses favorite words, like "flummery," "fatuous," and "futile." Archie remarks that Wolfe might be better at reporting events than he is, if you like long words. Wolfe's words are carefully chosen, though, for meaning and connotation. Wragg, Cramer, and Archie are as careful in their words as Wolfe, picking and choosing the right meanings to convey, which is especially necessary in a battle where the FBI is always presumed to be listening. Wragg even refuses to admit that he's had Mrs. Bruner under surveillance, and Wolfe must reword his demand to account for Wragg's denial.
