The Civil Liberties investigation in Washington has made industrial espionage and strike breaking front page news. This book is based on the shocking disclosures made in this investigation. It dramatizes and highlights the despicable use of spies and strike breakers and does not make pleasant reading for the T.B.M. It shows how industry is itself being trapped by the very system it inaugurated to trap labor. Although somewhat biased, the author does a sincere job in showing up the Espionage Combine of Burns , Pinkerton, etc., and the manufacturers of tear gas and tear gas equipment. The human element is brought in through tragic cases of suffering of individuals. A book of timely and historical value for those interested in labor problems today.
