Colson Whitehead’s Cool Machine is the third and final novel in his Harlem Trilogy, concluding a multi-decade story centered on its protagonist, Ray Carney. The series begins with Harlem Shuffle (2021), which introduces Carney in 1959 as the owner of a legitimate Harlem furniture store who also fences stolen goods. The son of a criminal who worked as muscle, Carney has tried to build a more stable and respectable life for his own family. His reckless cousin Freddie draws him more deeply into Harlem’s criminal world by involving him in the robbery of the Hotel Theresa, after which Carney must contend with the violent consequences of the heist. As the novel moves through 1961 and 1964, his furniture business expands as his dealings bring him into contact with criminals, corrupt police officers, and influential figures in Harlem.

The second book, Crook Manifesto (2023), moves through 1971, 1973, and 1976 against the changing social and political landscape of 1970s New York City. In 1971, Carney has stopped fencing stolen goods, but his search for sold-out Jackson 5 tickets for his daughter May leads him to the corrupt police detective Munson and back into criminal activity. In 1973, the focus shifts partly to Pepper, Carney’s longtime criminal associate, who takes a security job on a Blaxploitation film shooting in Harlem and becomes involved in the search for its missing leading lady. The final section takes place during the 1976 Bicentennial, when a fire that injures one of Carney’s tenants leads him to ask Pepper to investigate, drawing them into an arson scheme tied to political corruption and redevelopment.

By the time Cool Machine opens in 1981, Carney is older, financially established, and deeply familiar with the criminal networks that operate alongside the city’s legitimate businesses and institutions. The preceding novels establish the personal and urban history behind Carney’s circumstances in Cool Machine, as he encounters new forms of crime in a city that has changed around him. This continuity is captured in the novel’s opening description of a New York where crime “devise[s] new permutations daily” (3).
