(Later, while in the actual process of writing, I found that I could make the whole theme of stolen knowledge ironical by having Fred Daniels discover knowledge whose utmost value he would not exactly understand and on the basis of this contrive his death for a knowledge he possesses which is not of the highest value. Actually, Fred Daniels is not killed for the really dangerous knowledge he thinks he possesses, but for fear that he might betray secrets of the police department!)
