The Troubles in Northern Ireland was a difficult, bloody period, which lasted for almost 30 years. During that time, the British secret services ran an extensive intelligence operation to infiltrate the IRA, the details of which are only now coming to light. Speaking to David Musgrove, Henry Hemming discusses what he uncovered about this secret web of spies, agents and double agents for his new book Four Shots in the Night. (Ad) Henry Hemming is the author of Four Shots in the Night: A True Story of Spies, Murder, and Justice in Northern Ireland (Quercus, 2024).
