'One Bold Deed of Open Treason' describes the astonishing journey by Roger Casement to Germany in 1914, via New York and Norway. Arriving into Berlin under a false identity, Casement entered a space of conspiracy and subterfuge. Through his vivid and gripping diary entries, a picture emerges of a man caught in the crossfire of international events and spiralling towards a tragic denouement.
In recording his daily thoughts, emotions and movements, Casement chronicles his despair at the conflict he witnessed, his hopeless mission to raise an Irish brigade and his attempts to promote the cause of Ireland in an escalating world crisis. With an expert editorial hand, Angus Mitchell provides clear context to Casement's diaries, revealing his gruelling visit to the Western Front, the shocking interplay between the Easter Rising and the international theatre of the First World War, and the grand, sacrificial conclusion of his life.
