Here, as with his Pulitzer Prize-winning Peter the Great (1980), Massie disdains the virtues of literary economy. Yet this history of pre-WW I super-rivalry is much more than an imposing doorstop, for the author is a master of the Barbara Tuchman/William Manchester school of popular history. If there is a villain of this epic, it is Germany's Kaiser William II. Autocratic, bellicose, and tactless enough to refer to British ministers as ``unmitigated noodles,'' he understandably grieved his grandmother and uncle, Britain's Queen Victoria and the Prince of Wales (later King Edward VII). In his desire for Weltmacht (world power), William, in 1887, decided to complement the world's most powerful army with a formidable battle fleet, so alarming Great Britain that it ended its foreign policy of ``Splendid Isolation'' from Continental affairs and began a frantic shipbuilding program of its own. Massie follows the fortunes of the two countries through colonial disputes, secret understandings with former foes, high-wire diplomacy, and tit-for-tat building of dreadnoughts (the class of fast, all-big-gun battleships named for the innovative British vessel built in 1906). Like 19th-century novelists, Massie employs an epic narrative that leisurely explores characters, including such military and political figures as Admirals Alfred von Tirpitz and John Fisher, the commanders who radically transformed their countries' naval defenses; Bernard von Bulow, the cynical German Chancellor who ``lacked purpose, scruples, courage, and a vision of his own''; and Winston Churchill. A dramatic re-creation of the diplomatic minuets and military brinkmanship that preceded, and made inevitable, the guns of August 1914 and the resulting catastrophes of this century.
