'James Worrall has produced the most definitive account regarding the history of Anglo-Omani relations. Rich in detail yet nuanced in interpretation, this book will be invaluable to all those who want to understand why the Sultanate of Oman has developed in the way that it has, and how these ties- both strategic and economic- have managed to endure for so long.' Professor Clive Jones, Chair in Regional Security, School of Government and International Affairs, Durham University.
