Jeremy Garnet, hearing that his old friend Ukridge has called while he was out, and fearing that the peace he needs to plan his next book is about to be disturbed, decides to leave London for a time. But he is too late. Ukridge arrives, with his wife Millie in tow and immediately starts explaining his new get-rich-quick scheme, involving producing hen's eggs on a farm in Dorset. Giving in to Ukridge's forceful personality, Garnet agrees to accompany him to the farm; there will, Ukridge assures him, be plenty of golf and sea-bathing available. On the train to Dorset, they are joined in a compartment by a pretty, brown-haired girl named Phyllis and her elderly Irish father. By coincidence, Phyllis is reading a copy of Garnet's new novel, given to her by Molly MacEachern.
