Jeeves has his own club, the Junior Ganymede, for butlers, where the "Book of Revelations" records the flaws of their employers. The story unfolds when this book goes missing and falls into potentially dangerous hands.
George Uffenham, the eccentric sixth Viscount of Uffenham, has sold most of his family fortune to buy jewelry he then hides in a secret place. Victim of a car accident, he loses his memory and can no longer remember where he hid the jewels. This forces him to leave the family pile and to return there, posing as a butler, to search for the lost gems.
Once a man of the Hon. Galahad Threepwood's calibre and reputation starts taking pen in hand and writing Reminiscences, the nobility and gentry of all England recall past follies committed in his company and tremble. All rally to prevent their publication, and the consequences prove somewhat unusual: Lord Emsworth's prize-winning sow, Empress of Blandings, is kidnapped; yet another imposter is introduced into the ancestral home; and once again Blandings Castle proves too much for the Efficient Baxter.
