The East German scientist Professor Gerlach has made a significant discovery with his research into how a new, even stronger pesticide can be protected against ineffectiveness through hydrolysis. This fact has not gone unnoticed by other interested nations. At the International Congress of Chemists in Geneva, a power struggle broke out between agents of the BND and the CIA over a preparation that had been smuggled into Switzerland without the knowledge of Dr. Werner, Gerlach's GDR representative and assistant, and which the enemies hoped would shed light on the composition of the invention.
