What is the main conflict in Thank You, Jeeves by P.G. Wodehouse?

In the novel, Bertram Wooster finds himself in the uncomfortable position of having to choose between his new hobby of playing the banjolele and losing his home and loyal employee or giving up the one hobby that gives him some measure of pleasure. Bertram chooses the banjolele, leaving Jeeves with no choice but to take a position with Bertram's school chum, Chuffy. At the same time, Bertram moves to a small cottage in the little town belonging to Chuffy in order to give himself the space he needs to continue his study of the banjolele. Upon his arrival, Bertram learns that his dreaded enemy, the psychiatrist Sir Roderick Glossop, is engaged to Chuffy's aunt, the Dowager Lady Chuffnell, and has brought to Chuffnell Regis with him Bertram's ex-fiancee, her brother, and father.
