Complete and unabridged, with 56 full-page plates by Walter Sickert, Jean Béraud and James 'Clock' Shaw. Crowned heads meet in Vienna and put their names to something England badly needs to see; Bellamy, the King's Spy, has failed to find out what, and the hunt for the document — by way of an opera singer all Vienna raves about, and a great deal of money — becomes a race against a European war. Oppenheim wrote more than a hundred thrillers, dictating them to a secretary while walking on the Riviera. Fifty-six plates of Sickert and Manet, from Dieppe station to the antique shop, catch the gaslit, opera-going Europe of the chase.
