It’s not a joke. Wolfe is both a genius crime solver with an official license and an almost total recluse who spends all his time in his house growing orchids and enjoying the hard work of his private chef.
He has a hard working assistant who brings Wolfe people to interrogate. Archie is the one who writes the stories and finds the clues, but it’s Nero who actually solves the cases.
“The League of Frightened Men” by Rex Stout is one of the best of the series. It was originally published in 1932 and is still in print.

Frank Zappa siad something like this; in the 1960’s a bunch of music execs who liked Frank Sinatra and Louis Armstrong had to deal with the new wave coming in. They decided to throw money at every band they could find and as a result we got music ranging from The Mama’s and The Papas to Iron Butterfly and beyond.
By the 1970s the next wave of record execs had realized that Motown acts all looked and sounded the same, but they made a lot of money. One Motown was fantastic, but dozens of them meant that everything was going to start looking and sounding the same.
Similar thing with the movies. Lots of wild experimental movies like Easy Rider and The Conversation got made in the 1970s, but when Star Wars came in the studios found their goldmine.
