The Secret Vanguard by Michael Innes

4.0

I had forgotten what rousingly good mysteries the “Appleby” books are! Appleby himself takes second stage to the main characters, amateurs Stella Grant and Dick Evans, who get caught up in a nest of spies and with relatively minor help from the authorities (including Appleby himself), manage to bring down the baddies and rescue the valuable boffin.
