Answer
The answer is Nero Wolfe, a brilliant and eccentric detective created by Rex Stout. Wolfe, known for his love of orchids, operates from his brownstone on West 35th Street in New York City, and is assisted by his loyal right-hand man, Archie Goodwin. Wolfe's cases often involve complex puzzles and his analytical prowess, coupled with Archie's investigative skills, make them a formidable duo in the world of mystery fiction.
