While Senior History Master of Queen's School, Newminster, Carolus Deene has a troubling hobby as a criminologist and sometime sleuth. Even more troublingly, he has jaundice. But with the papers shouting of the crimewave sweeping the seaside resorts of England, sending him to the coast to recover is too risky for the Headmaster he will be much further from trouble in the inland spa resort of Buddington.

But before long Buddington is rocked by a twisted double-murder two elderly women found dead on the same night at the same time, each with a white lily by their side. Perhaps things are looking up for the curious Deene?

First published in 1960, Leo Bruce's classic mystery hums with his trademark wit and comedic flair, centred around an intelligent puzzle and a memorable cast of Buddington's best.
