The Enemy Within

Martin Dillon, a Belfast journalist regarded as an authority on Irish terrorism, presents material on the IRA's "England department" - how it has functioned and what its objectives are. He also provides evidence of political and military mistakes which he argues have made British cities the most vulnerable in Europe to terrorist attack. He explains why he believes that the various government agencies combating the IRA have failed to eradicate the threat, and describes the intrigue which led to MI5 taking responsibility for co-ordinating the war against the Provos. Dillon's other books include "The Shankill Butchers" and "The Dirty War".
