DAY OF WRATH It's a blood-chilling, all-to-plausible question, and one only Larry Bond dares to ask: What if the world's wealthiest man were also the world's deadliest terrorist?   A plane carrying an American arms inspection team mysteriously crashes in Russia. Not long afterward, a senior American diplomat is assassinated. The warning shots have been fired. A bold gambit to destroy America as a world power is well under way.  Its architect is Prince Ibrahim al Saud, a member of the Middle East's most influential royal family and the head of a multibillion-dollar global conglomerate. He is also "The Paymaster." With his vast wealth, he bankrolls the most lethal terrorist groups on earth to launch the most murderous attack ever conceived. Against Ibrahim and his allies stand two veteran American operatives listeners will remember from The Enemy Within: U.S. Army Colonel Peter Thorn and FBI Special Agent Helen Gray. Together they follow Ibrahim's scheme from Russia, across Europe, and finally home to America -- all the while on the run from the very people they're fighting to protect.   Ibrahim plans to wreak devastation on the United States in a single, apocalyptic millisecond, altering history forever. And he knows that Thorn and Gray, though formidable, are still human. They can be trapped, caught, and killed. The Operation is in its final moments. Now nothing can stop it....
