The Big Four

Four men were out to rule the earth. One was a fabulously powerful Oriental, one a diabolically brilliant French scientist, one an incredibly wealthy American. The fourth—and most dangerous—was a master murderer whose identity was cloaked in awesome mystery.

This fiendish quartet had every instrument of destruction at their disposal to carry out their plans—and only one man stood in their way. Fortunately for the world, his name was Hercule Poirot....

But now the greatest sleuth of them all found himself in a situation that would have staggered even the fabulous 007.

A gigantic global conspiracy was tightening its net of terror around the forces of law and order wherever they might be—and the governments of the world were helpless to defend themselves.
