Department of Death — John Creasey

Department Z is an ultra-secret British Intelligence Agency made up of civilian, single men, risking their lives to protect their country. All tasks are hush-hush and ulterior tactics are used, anything to stop the enemy. A summit of the world's most powerful nations is underway and Jonathan Grant, a new recruit to Department Z, is risking his life to stop the summit turning into a mass killing, all with the help of the enigmatic Marlene von Barlack and her little black book of politicians.
