John le Carre 
A Murder of Quality 

A murder mystery in the finest tradition of English detective novels, John le Carré»s A Murder of Quality is an ingenious puzzle featuring his best-loved character George Smiley.
Stella Rode has twice disturbed the ancient cloisters of Carne School: firstly by being the wrong sort, with her doilies and china ducks, and secondly by being murdered. George Smiley, who has his own connection with the school, is asked by an old Service friend to investigate. Smiley knows that Stella feared her husband would murder her, but as he probes further beneath Carne»s respectable veneer, he uncovers far more than a simple crime of passion. In his second George Smiley novel, le Carré moves outside the world of espionage to reveal the secrets at the heart of another particularly English institution. The result is a pitch-perfect murder mystery, with Smiley as master detective.
