'The British secret service is world renowned and intelligence gathering is often cited as one area where Britain remains in the big league, writes RTÉ's London Correspondent John Kilraine.During The Troubles the activities of British Intelligence through such shadowy organisations as the Force Research Unit (FRU) have been well documented and have included clandestine operations and black propaganda (also known as Psy Ops). Given this background it is inconceivable that British Intelligence would not have taken an interest in the Republic of Ireland during this period...While most previous investigations into the British secret service in Ireland have concentrated on the North, Enemy of the Crown by David Burke draws together a lot of the evidence about its activities in the Republic, mainly involving MI6...assembling and establishing sources for such a mass of information – there is a lot more than can be covered in a book review - is a mammoth task. Burke has produced a well-researched book with an extensive bibliography, glossary of terms used, list of characters and an index that all endeavour to provide cross reference. He also comes up with new revelations such as a German gun supplier being the MI6 source concerning an abortive arms shipment to Dublin in 1970. The guns were intended for the defence of Northern nationalists. Enemy of the Crown is important piece of work that shines a light on an area that needs some exposure. It is also a good read.https://www.rte.ie/culture/2022/1212/1341337-book-of-the-week-an-enemy-of-the-crown-by-david-burke/
