American arms merchant Blacky Lee is wanted by nearly every government in 1930s Europe; especially the Nazis. They want Blacky's head for selling them dud weapons, prompting his rapid (and illegal) escape across the Balkans to the kingdom of Aldoria with his business partner in tow. Aldoria is well chosen. Years before, Blacky discovered he was the spitting image of the country's Prince Philip, learned the archduke's speaking voice and memorized the royal family tree just in case. When Blacky brazenly impersonates the leader, things go surprisingly well . . . that is, until he finds himself caught in the middle of a Communist plot to rig elections and take over.
Prolific pulp-fiction author Hubbard (1911 1986) offers a variation on a familiar romantic theme with this fast-paced if derivative thriller set in pre-WWII Europe. Blacky Lee, an American weapons dealer, just happens to be the spitting image of Archduke Philip of Aldoria, a coincidence that enables him to dodge Nazis and ensnare the heart of the attractive Countess Zita, plot elements familiar to readers of Anthony Hope's The Prisoner of Zenda and Rupert of Hentzau. Those 19th-century swashbucklers successfully blend action with emotion, while Hubbard's breezy romp is only an easily digested, quickly forgotten time-filler.
