'The most complete narrative to date of the issues involving the conflict between the British government and the Irish movement for independence in the Great War era...I recommend it to you with enthusiasm.' - Martin A Miller, Professor in the Department of History at Duke University, USA 'The great strengths of this manuscript, I think, are that it opens new material to scholarly analysis, expands our understanding of the Irish rebellion, and intersects with a growing body of literature on the history of intelligence.' - Alex Roland, Duke University, USA
