The Poisoners

Dr. Essley is in search of the Four Just Men. He has been told that they have disappeared from the face of the earth and that they were certainly not domiciled in France. He seeks the help of De la Monte, an author. George Manfred, enjoys some reputation as a quasi-scientific literateur, and under the name of "De la Monte" had published a book on "Modern Crime." Why is Dr. Essley searching for the Four Just Men? Will De la Monte help him in his quest?
