In 'best seller', O.Henry describes quite an interesting character,John A.pescud, a travelling  salesman for glass and plates company. pescud appears to be just the kind of characters that is so commonly found in the best-seller like "The Rose Lady and Trevelyan".he criticises the best seller as they 
are far removed from real life.Their heroes,scenes and characters produce a 
false world of romance and idealism . Ironically , John A.pescud  does exactly
the same what he opposes and criticises in the best seller . He is another Trevelyan who tries to sell his romantic story and ultimately marries his 'princess' Jessie . The narrator's last words are quite meaningful . 'Good-luck to you ,Trevelyan and may you get the petunias  for your princess!".
