Against a background of the British invasion of the First World War and the subsequent civil war, Lyell presents a portrait of life as he saw it. He explodes in detail the influence of religion on Arab life, both in its domination of everyday affairs and in the antipathy between orthodox Sunnis and unorthodox Shias, believing an appreciation of this to be crucial to any understanding of the area. Although his experiences as a criminal judge may have coloured his views towards the Arabs (whom he considered lawless and unfit for self-government), he is equally castigating of British, Jewish and Kurdish peoples in the region (bemoaning British folly in placing a Sunni of the throne of largely Shia Iraq, and referring to the Kurds as "untrained savages").
Commenting, in the final section of the book, on the possible future of Iraq, Lyell has grim warnings. He foresaw the influence of the Red Army in the area, the threat of a Kurdish revolution and, in the event of the British pulling out and leaving the Iraqis to govern themselves, a bleak future for the minority elements in the country: "... no conceivable guarantees in the world ensure their safety ... All modern civilization and progress would be wiped out."
