First published serially in 1923, and later as a novel in 1924, "Leave it to Psmith" is P. G. Wodehouse's fourth and final novel starring one of his most beloved characters, the clever and witty Psmith. He is called Ronald Eustace Psmith in this installment, rather than Rupert Psmith as in previous books, likely to distinguish him from another character in the tale. Psmith has snuck himself into Blandings Castle to foil a plot to steal a very valuable diamond necklace belonging to a relative of his good friend Mike Jackson's wife, the haughty Aunt Constance. Psmith uses his wit and intelligence to uncover the dastardly scheme and thwart the would-be robbers all while employing his customary charm to flirt with lovely ladies employed in the castle. In this comical and adventurous tale Psmith manages to do it all: save the necklace from the thieves, help his friend Mike fund a new business venture, win the heart of a beautiful young lady, and talk his way into a promising new job. "Leave it to Psmith" has been adapted many times for the stage and television and continues to this day to entertain readers and audiences alike. This edition includes a biographical afterword.
