Richard Gordon 
Nuts In May [PDF ebook] 

Algernon Brickwood, successful publisher and proud father, is known to enjoy a spot of lunch or two. And it is over one such lunch that Teddy, his beloved son, drops his bombshell. He has been sent down from Oxford – and not only that, but he’s also broken off his engagement to Abigail Fitzhammond. Now Algernon can live without the Oxford connection, but certainly not the family’s impending union with the lovely, and rather rich, Abigail. As he determines to put a stop to his son’s pig-headedness, Richard Gordon takes him, Teddy and Abigail on a uproarious romp through love, money and a taste for high living.
