The absent minded Lord Emsworth finds himself once again embroiled in fierce rivalry in the pig-rearing arena with his neighbour, the obese baronet Sir Gregory Parsloe-Parsloe.
With Emsworth's champion Empress of Blandings in line for a third straight victory in the local show and Parsloe bringing in a ringer, suspicions run high.
Lord Emsworth, his brother Galahad and butler Beach, hearing that devious neighbour Sir Gregory Parsloe-Parsloe has done the unthinkable and brought in a new and enormous pig from Kent, are in turmoil.
Hearing about this suspicious purchase, a worried Galahad calls in Beach's niece Maudie, an old acquaintance and now proprietor of a Detective Agency, to keep an eye on things.
Meanwhile, Emsworth, stricken with a cold, has been smitten by Maudie (posing as Mr Donaldson's old friend Mrs Bunbury), and writes a letter to her declaring his love, which he has Vail place in her room.
He then persuades Emsworth to invest in Vail's health farm, in gratitude for having found the pig, and Connie gives him another £500 for Beach, to prevent him suing Parsloe for wrongful arrest.
