Lawson, John D., American State Trials, vol 13, Thomas Law Book Company, 1921, p. viii: "After his death and after we were in the war they issued a seventh volume of this series, entitled "The Finished Mystery," which, under the guise of being a posthumous work of Pastor Russell, included an attack on the war and an attack on patriotism, which were not written by Pastor Russell and could not have possibly been written by him."
