One of the riders at a fashionable fox hunt must have bludgeoned wealthy W. H. O. IV (pronounced ""Who Four"") to death with a horseshoe. The suspects in the Hunt Club include an old flame of Burke's and her arrogant husband (who never stops needling Burke), a nouveau riche Texan, and a ""little old lady from Pasadena"". Last but not least is the dead man's butler, who may have more money than his master. And what about the sexy Prudence, who may or may not provide a clue or an alibi? Burke finally discovers that the killer may have clubbed the ""wrong"" victim.
