What a shocking book cover! I have not seen it before. Anyway, Greene sets the story just as the French are losing Indo-China and the Americans are stepping in. It is a brilliant and cynical observation of empire and national ambition at the cost of individual liberty and conscience. Or something.
"It's Oh So Quiet" was covered by Björk in 1995 and remains her biggest hit, reaching #4 in the UK. It's originally sung by American singer Betty Hutton, released in 1951. It is a cover of the German song "Und jetzt ist es still", performed by Horst Winter in 1948.
