Deep in the world's greatest desert, the leadership of Al Qaeda, hunted and pursued, is regrouping to strike again. In this group one man stands out. His loyalty to the cause is total.

If the Outsider is allowed to disappear again, he will re-emerge in a busy western city with a suitcase designed to wreak mass murder on detonation . . .
