Fellow-writers Ashe Marson and Joan Valentine

Newly met and both in need of a change of direction, they find themselves drawn to Blandings, for various reasons attempting to retrieve a scarab belonging to an American millionaire, absent-mindedly purloined by Lord Emsworth.

Once within the Castle's walls, despite impersonating servants, romance cannot help but blossom; meanwhile, Freddie Threepwood, engaged to the millionaire's daughter, is worried about some incriminating letters.
