This book was great. Well-researched and outlines with a marvelous arc that you could only think you could get from fiction, Puelo has done an amazing job reconstructing what it was like in 1916-1925 Boston in order to explain the events leading up to the molasses flood which is a thing a lot of locals make jokes about but few really understand. I particularly enjoyed the extra outlining of the political climate of the time describing anarchist activity that was going on in the area and also describing how the tank owners tried to pin the blame on political rabble rousers instead of their own cost cutting measures.
