I read this book after reading Gary Phillips' Matthew Henson & the Ice Temple of Harlem, a New Pulp actioner set during the Harlem Renaissance. Phillips used the real-life Stephanie St. Claire as one of the background characters, and she was such a fascinating woman that I needed to learn more.
A Caribbean immigrant who rose to control much of the numbers racket in 1920s and 1930s Harlem, Stephanie St. Clair took on mobsters like Dutch Schultz and Lucky Luciano as well as corrupt police. She would take out advertisements in the papers listing the names and badge numbers of the cops who tried to shake her down, as well as to educate her fellow Harlemites on their rights when the cops resorted to illegal searches and seizures. And though she was a criminal, she was also a dedicated investor in her community, a civil rights activist, and a philanthropist. Her telegram to Dutch Schultz on his deathbed is legendary, but her own downfall was just as humiliating.
McBrayer, early on, admits that she's engaged in "creative non-fiction," making up whole swatches of dialogue and detail. She was, no doubt, caught in a bind. There was too little documentary evidence for a full, scholarly biography, yet she didn't feel up to the task of writing the novel that this character deserved. McBrayer has her moments, though. Her description of the insanity of the 1935 Harlem riots, which began over a kid shoplifting a pocket knife, is reminiscent of something out of a Chester Himes Harlem Detective novel. I kept expecting Grave Digger Jones and Coffin Ed Johnson to make an appearance. McBrayer's description of St. Clair's relationship with Sufi Abdul Hamid, the "Black Hitler," was also luridly enthralling. Thus, we get a work that is half-and-half.
There are some additional problems with McBrayer's work. First, I'm not sure she understands mathematics: some of her explanations of craps and the numbers racket make little sense. Also, she occasionally includes material that requires further explanation, such as what Mechanics' Night on Thursdays meant in terms of an exception to the segregation of the Cotton Club, or that St. Clair's butler, Bridget, was male. It was also a bit disturbing to find important details on St. Clair's Wikipedia page that are not in McBrayer's book. There are two other biographies of St. Clair out there that may clarify these lacunae.
