Thank You, Jeeves by P. G. Wodehouse

Bertram Wooster's interminable banjolele playing has driven Jeeves, his otherwise steadfast gentleman's gentleman, to give notice. The foppish aristocrat cannot survive for long without his Shakespeare-quoting and problem-solving valet, however, and after a narrowly escaped forced marriage, a cottage fire, and a great butter theft, the celebrated literary odd couple are happy to return to the way things were.
