One by one they knock on the door of the incomparable Nero Wolfe, each with a case more perplexing than the one before. First comes the niece of a man who committed suicide by jumping naked into a geyser, only to return just in time to be murdered. Then it's the strange case of the murder victim's family covering up for the real killer, while a chef stews in jail. Finally a master horticulturist discovers the woman he wants to marry: dead and cooling in a hothouse. Three knocks on the door. Three cases of crime. Enter a world of mendacity, mixed motives, and masterful detection on West Thirty-fifth Street, where murder is always at home.
