[2] J. G. "Jeff" Miller, a jovial and athletic writer of thrillers, attempts a career as a lawyer at the insistence of his imposing fiancée Myrtle Shoesmith.
The man, crooked American private detective Chimp Twist, thinks he is being attacked by one of the victims from his career of petty crime, and hides in a closet.
Niece and uncle explain that Lord Uffenham keeps the family wealth as a cache of diamonds, hidden in continuously changed locations around his ancestral home of Shipley Hall.
Needing a source of money while he searches for the diamonds, he has rented Shipley Hall to Anne's employer Clarissa Cork, a famous hunter, explorer, and health crusader who has turned the place into a vegetarian resort.
To retain access to the property, Lord Uffenham has been masquerading as Cakebread, the butler, whom the lease forbids Mrs Cork to fire.
Jeff goes to the Hall and meets Mrs Cork, who expands his duties to watching her nephew Lionel Green and Anne Benedick, as she fears they are romantically involved.
Dolly visits Chimp in London to learn what has gone wrong and he tells her about the diamonds, suggesting that the Molloys steal them and split the proceeds with him.
Dolly and Soapy are obliged to keep Jeff's secret, because he has seen them covertly eating meat and can get them expelled from the vegetarian colony, which would ruin their chance of finding the loot.
Twist saves himself by revealing Jeff's true identity— J. G. Miller, the man Anne and Mrs Cork both despise for being nasty to Lionel Green in court.
The Molloys drive away with the jar and Lord Uffenham releases Mrs Cork and Mr Trumper, who discovered their love for one another while in the cellar and are now engaged.
"[3] George, sixth viscount Uffenham, a typically impecunious and absent-minded Wodehousian aristocrat appears later in the novel Something Fishy (1957), where he helps Anne's sister Jane.
The story also features the crooks Alexander "Chimp" Twist and "Dolly" and "Soapy" Molloy, who had earlier appeared in Sam the Sudden (1925) and Money for Nothing (1928).
