Queen and Country, Volume 3: Operation: Crystal Ball — Greg Rucka

Mahmoud Youseff, a Lebanese citizen, walks into a British Embassy in Cairo, declaring himself to be a member of the Group Islamique Arme and claiming to have information about a plot by the Egyptian Islamic Jihad to launch a terrorist attack on British citizens. Tara Chace, the operative designated Minder Two of the Special Section of the SIS, is immediately dispatched to meet with Youseff and strike a deal. What follows is a frenetic search across the world for the EIJ's stockpile of Sarin gas and, more importantly, where they plan to unleash it. Sarajevo, Baghdad, Rome, Osaka -- the Minders are determined to halt this deadly game before it even gets started.
