Aunts Aren't Gentlemen

When the doctor advises Bertie to live the quiet life, he and Jeeves head for the pure air and peace of Maiden Eggesford. However, they hadn't reckoned on Bertie's irrepressible but decidedly scheming Aunt Dahlia, around whom an imbroglio of impressive
proportions develops involving The Cat Which Kept Popping Up When Least Expected. As Bertie observes, whatever aunts are, they are not gentlemen.

A classic - the last book written by Wodehouse featuring Bertie and Jeeves.
