The city of Shahrazar has fallen to the Turkomans under Orkhan Bahadur. Since O'Donnell -- still disguised as the Kurd, Ali el Ghazi -- once saved Orkhan's life, he has become the Turkoman's "cup-companion", Orkhan little knowing that it was O'Donnell who disposed of the treasure of Khuwarezm. But then, O'Donnell is found out by the (possibly) disguised European, Suleiman Pasha, and Suleiman decides to use that knowledge to force O'Donnell to be his agent. It seems the tribesmen of Kuruk discovered an Englishman dying in the Afghan hills and carrying secret papers, papers which Suleiman wants to get his grimy mitts on. He convinces Orkhan Bahadur to send O'Donnell with some men to recover the papers, intending that, in reality, O'Donnell will be working for him (Suleiman). But when O'Donnell reaches the Pass of Akbar, he discovers the Kurukzai has been run out and replaced by a motley crew of rogues led by the notorious Yusufzai, Afzal Khan, who men call "The Butcher"...
