The book dedicated to Bulgaria is from the early ones in this series (1889) and contains touches from the creative portrait of its author, but also authentic evidence of the political and social situation in the country, as well as comments on its external relations and their perspectives. "In Bulgaria after the Unification" is an essay that combines elements of travelogue and reportage. With a keen eye for detail and well-intentioned objectivity, the author talks about his journey by rail to Sofia, about the infrastructure of the capital, about his brief visit to Plovdiv to the "Balkan Neapolitans", about his talks with Prince Ferdinand, Georgi Stranski, Count De Greno, and for a memorable and emotional meeting with Stefan Stambolov.
