I've been trying with it but I am just getting nowhere. I keep loosing whatever thread there is of a plot and it seems it won't get much better based on other reviews.

Reading this book was hard work. Firstly the German writing style is difficult. Secondly there was no drama.
The story gave only a ghostly sketch of Sir Richard Burton, who somehow did not come to life.
No doubt that the man was a fascinating character, a linguist and a traveller who was the first westerner to go on pilgrimage to Mecca. A man who translated the Kamasutra and spoke so many languages, and lived so many different lives.
The book only gives glimpses of his personality through the re-telling of his travels from three different viewpoints: The narrator of the first part is Burton's servant in India, the second part is narrated by officials in the Ottoman empire investigating his trip to the Islamic holy cities and the third part is narrated by the African guide who accompanied Burton and Speke on their trip in East Africa to find the source of the Nile.
The effect of this narration is to give the central character a back-seat, so we only get to see him through the eyes of others. This worked partially well in the first part where the servant was reasonably close to Burton, but in the two other parts it gave only a distant picture of the man and his adventure. The descriptions are long and there are pages upon pages of non-events. The book raised more questions about Richard Burton than it answered and I think I will have to meet him again in another biography. ( )

Ein spannender Roman über den englischen Abenteurer Richard Burton (1821-1890). Anstatt in den Kolonien die englischen Lebensgewohnheiten fortzuführen, lernt er wie besessen die Sprachen des Landes, vertieft sich in fremde Religionen und reist zum Schrecken der Behörden anonym in den Kolonien herum. Trojanows farbiger Abenteuerroman über diesen Exzentriker zeigt, warum der Westen bis heute nichts von den Geheimnissen der anderen Welt begriffen hat.

This novel is based on the life of Sir Richard Burton, the famous explorer whose translation of the 'Arabian Nights' scandalized Victorian society. Troyanov imagines Burton through the eyes of an Indian servant, an Ottoman governor, and a former slave who acted as Burton's guide.
