Disruption: Inside the Largest Counterterrorism Investigation in History
"An outstanding contribution to the literature of terrorism and counterterrorism."

Kirkus, Starred Review!

"Peritz gets deep into the weeds of the various terrorist cells involved, but paints a detailed portrait of a tragedy narrowly averted. Readers will gain new appreciation for what it takes to stop the next terrorist attack."

Publishers Weekly

"Some of the mea­sures put in place since 9/11, as in­con­ve­nient as they may be, have un­doubt­edly saved lives. We might still de­bate their use­ful­ness and le­gal­ity, but we should do so with a full un­der­stand-ing of their re­sults. “Dis­rup­tion” is a valu­able con­tri­bu­tion to that un­der­stand­ing."

The Wall Street Journal

"[A] gripping account of a complex and ultimately successful counterterrorism investigation"

Foreign Affairs

"Disruption is a deeply researched and reported examination of a plot by largely Britain-based al Qa’ida supporters [...] full of hard to believe (but true) stories"

The Cipher Brief

"Peritz’s step-by-step account of the planning of Overt and the painstaking police work by which Scotland Yard learned what was afoot reads almost like a le Carré novel. “Disruption” is utterly gripping."

The Christian Science Monitor

“A fascinating read. There are secrets in this book even I didn’t know.”

Gen. Michael V. Hayden, U.S. Air Force (Ret.), former director of the Central Intelligence Agency and the National Security Agency

“This operation remains the gold standard for how America and Great Britain came together to crush the greatest conspiracy since 9/11. Disruption knocks it out of the park.”

Fran Townsend, assistant to the president for Homeland Security and Counterterrorism
