Like Zenda, Phroso is 'a Romance' in both senses of the word. (At the time, 'romance' usually referred to the adventure genre, and implied that it was not true to life. Also like Zenda, it's about a hearty young Englishman of bold character, who takes a vacation in a fictional country and finds himself caught up in all sorts of skullduggery. (Zenda actually defined this genre originally -- it's called a 'Ruritanian Romance' named after the nation of Ruritania where Zenda takes place.)
