Agatha Christie’s The Big Four: a tale of international intrigue and espionage.

When an unexpected visitor bursts into Hercule Poirot's home and collapses onto the floor, the atmosphere becomes charged with intrigue. The only clue to his purpose is the repetition of Poirot's name and address, accompanied by the insistent scribbling of the number four. Gradually, the man regains consciousness and begins to divulge information about an insidious international crime syndicate known as "the Big Four".

But the man dies soon after Poirot and Hastings go off on the trail of the Big Four.

Intrigued by the visitor's revelation, Poirot delves deeper into the matter and soon uncovers the startling truth. The Big Four has ingeniously devised a revolutionary form of wireless energy capable of focusing an immensely powerful beam on any desired target. The implications of such a weapon are both staggering and ominous.
