Nero Wolfe is a fictional detective created by American author Rex Stout. He is a large, eccentric genius who solves seemingly impossible crimes with the help of his assistant Archie Goodwin. Wolfe's primary character trait is his extreme aversion to leaving his comfortable home, so he relies on Archie to do the legwork for him. The term 'Sleuth Wolfe' is often used to refer to Nero Wolfe and his investigative methods.
