Rollins did a lot of the spadework for investigation of unamerican activities. Too bad his material has been ""scooped"" by other books, by periodicals and newspapers, for it gives an exciting view of a working agent. Moreover this is interesting for its methods, its procedure, its evidence of a man alert and resourceful, much of whose evidence helped in the exposure of full fashioned Fascists. He put the finger on Palley's Silver Shirts; he found the channels through which German propaganda literature, uniforms and munitions were distributed; he put the spotlight on Fritz Kuhn, Dorothy Cogswell, Coughlin, McWilliams. Personal slant and human interest give this something of freshness, even though the findings are known.
