I Married a Communist by Philip Roth is usually described as a roman à clef about Roth’s marriage to Claire Bloom, but I pretty much missed all of that, and just read it as a Roth novel. I love many of the characters, especially the ones Roth loves (one of whom is not Nathan Zuckerman the protagonist). It’s hard not to feel for the spectacularly flawed “Iron Zinn,” and even more the older brother, Nathan’s teacher, who as a ninety year old narrates most of the story. The background is wonderfully detailed, especially the romance of communism for a brainy Jewish kid growing up in Newark, NJ at the end of the thirties and during WWII. We get a lot of the black list and McCarthyism of course, and it goes on too long in places. I like how Roth gets excited about various crafts (glove making in American Pastoral, taxidermy and rock collecting here), but he probably uses more of his research than the novel requires.
I don’t know if this is prime Roth, but second rate Roth is better than nine tenths of the books you read. Read and enjoy, Iron Inn and Murray the Teach and even tremulously manly Nathan Z., as they try to figure out America..
