What is the author's style in Scoundrel Time by Lillian Hellman?

Hellman's reluctance to believe that the government would treat her unfairly stood in the way of her recognizing the danger that lurked for her, many of her friends and indeed the country. However, even though she was somewhat slow on the uptake, her ability to have strong convictions and to stick to them, allowed her to stand up to the unfair, illegal actions of the US government. In the end, she admits that Russia was a danger to the US and that she like many others should have realized it sooner. Again, however, she did nothing ever to help Russia.
