I will now see the much lauded Spike Lee film based on this book. The description says it is drama, not comedy, but given Lee's reputation, I would not be surprised if it capitalized on the inherent humor of the situation that gets highlighted in the book. In many ways it's purely farcical!
I don't think it's very well written, not particularly well read by the author, but the story has a certain appeal, of course: In 1978 the first black policeman in the Colorado Springs, Colorado PD skims the local paper and finds an invitation to connect to the local chapter of the KKK. In short, he not only joins it, at the end becomes its leader, though this happens in a unique way. He talks on the phone with the local KKK group and arranges for his white partner to attend meetings. He actually becomes a card-carrying member of the KKK.
Along the way Stallworth becomes "friends" with David Duke, who in the highlight of the book comes to Colorado Springs to lead a KKK rally and Stallworth--a black man, remember--is assigned to be Duke's body guard. Preposterously, he actually manages to get a photograph taken with his arm around Duke's shoulder. The photograph was taken by his white colleague. So you see the crazy elements of farce here.
Not much really happens in the book. In the face of serious threats to our democracy by an increasing number of white hate groups, it is almost quaint to look at the handful of KKK folks in 1978 he documents gathering there. He admits that when he first signed a form to join, he signed HIS OWN NAME, though never got caught. No group seems really professional or well-organized, whether it is his own investigation or "Sting" operation, the KKK itself, David Duke, local anti-racist groups. He admits in his story that the KK locals are laughable, but also everyone protesting are laughable. He and his partner (who ALSO signs his OWN name mistakenly to a form at tone point and is not caught!) do not seem great in their work.
At one point Stallworth tells of a conversation with Duke where Duke says he knows Stallworth is of "pure, aryan descent" from his accent. So this is really a two star book for me except I think it is a bit funnier than the author intended. To his credit, in writing the book in the Trump era, he acknowledges the continued and growing white supremacism in the country, sadly noting that it is not gone away. He mentions some historical civil rights moments that inspired him in his work, too.
I was reminded of Karen Hesse's children's novel about the KKK in a small town in Vermont in 1924, Witness. I also read Black Like Me by John Howard Farrin about a white man who altered his skin chemically to "look black" and traveled the South to see if color alone would lead to different treatment (it did!). I also recall reading the graphic novel of a light-skinned black man who infiltrated the Klan, Incognegro by Mat Johnson.
