This book about the Troubles, covering the political violence in Northern Ireland from the 1960s to the late 80s, is written so intensely that it feels like a novel. At times you even wish it were a novel, because it’s so inescapably painful to remember that these are real people in history, who lived in terror while their friends and neighbors chose to enact violence and tragedy upon one another. Keefe tells the story by focusing on the individuals. He begins with Jean McConville, a widow who was taken directly from her home while her ten children watched and never seen again. Then he digs into the members of the paramilitary forces likely involved in her disappearance, giving voice to their anger, their pain, and their pride, without excusing their actions in the slightest. As the sad story moves on he also reveals government operations, both clandestine and open, and how those actions may well have done more to continue the violence than to defuse it. The book also covers the I.R.A.’s unlikely evolution from terrorist group to political party, the lies everyone told themselves in order to accept the transition peacefully, and the impact on those left behind, both within and without the I.R.A. Blamey’s Irish-accented narration, quiet but intense, is an amazing way to experience the book. “Say Nothing” is a brilliant title; it touches on the strict code of silence around the actions of the I.R.A., but also points to how those left in the aftermath would rather look the other way than dig up (sometimes literally) the problems that prompted the Troubles in the first place.
