Justin Quayle is a low-level British diplomat who has always gone about his work very quietly, not causing any problems. But after his radical wife Tessa is killed he becomes determined to find out why, thrusting himself into the middle of a very dangerous conspiracy.

In 1993, Canadian Lieutenant General Roméo Dallaire was sent by the United Nations to Rwanda as commander of the United Nations Assistance Mission for Rwanda (UNAMIR). Its mission, to ensure the ceasefire, is underfunded, excessively bureaucratized and made up of military units which come from dozens of countries and which each have a very different program... These are Lt Gen Dallaire's efforts to stop the madness of the Rwandan Genocide, despite the complete indifference of his superiors.
