But little does he expect to be faced with another kind of conflict – with a beautiful young hostage imprisoned in the Imam's stronghold. The lovely Natasha is only nineteen and she was seized along with a Royal party by the Imam's followers and held to ransom against the release of the Imam's only son by the Russians. Orphaned, she has no hope of raising a ransom and instead has reluctantly agreed to be given to the Sultan of Turkey as a 'wife' for his vast harem in return for the release of her nine-year-old brother. The Imam implores Lord Athelstan to escort Natasha safely to Constantinople – a favour he cannot grant lest it anger the Russians and compromise Great Britain.
