This book explores the assassination of Antonios Triantafyllides, a leading Cypriot lawyer and politician, in British colonial Cyprus in January 1934. This event has been the infamous subject of rumours since its occurrence and a taboo subject for Cypriot society and historians alike, as the event has been silenced or dismissed. This book explores the assassination in its broadest possible context by situating it within the broader events within the British Empire, the region and the world more generally at that time. The basis for the exploration is a ‘community of records’ through which all the evidence is sifted, reading it both with and against the grain, in order to provide the most likely answer to who was really behind this mysterious cold case. Through rigorous analysis, this book concludes that those who most likely masterminded the assassination supported radical right-wing extremist pro-enosis nationalism and were subsequently also prominent in forming the EOKA terrorist group in the 1950s.
