Archie Goodwin is not overly fond of Theodore Horstmann, who takes care of the orchids on the rooftop of Nero Wolfe's West Thirty-Fifth Street brownstone. But as loyal assistant to the legendary private detective, Archie will put his animosity aside when the surly orchid-keeper stumbles through the front door beaten within an inch of his life. While the gardener lies in a coma, Nero sends Archie to poke around his apartment near the river. The place is neatly kept, if not quite as elegant as the brownstone, but across the street on Tenth Avenue Archie quickly discovers the longshoremen's watering hole in whose back room Horstmann has been playing a lot of bridge lately. The smoky tavern is packed with tough dockworkers and recent European immigrants, and Archie does his best to blend in, filling the victim's empty seat in his running card game, as he attempts to learn what sort of shady business might have led to attempted murder. But when one of his new bridge partners is killed, Archie finds himself caught up in something much bigger than a bar fight.
