We are in Boston in 1919, at the close of the First World War.
The novel's protagonists are Danny, a police officer from a traditional white family whose patriarch is a high-ranking official in the police department, and Luther, a Black man who could have been a formidable baseball player, but, because he is Black, must resign himself to menial jobs.
This is, therefore, a deeply stratified American society, one in which the relations between social classes and different ethnic groups are clearly demarcated.
Both protagonists feel ill at ease within this rigid social framework.
Danny lives in the Italian neighborhood and is drawn to the social and ideological upheavals that characterize the years immediately following the end of the Second World War.
At first, it is mere curiosity, but he soon finds himself increasingly involved.
He is sent to infiltrate anarchist and Bolshevik groups as an informant, only to discover that they are simply demanding a more just society..
Meanwhile, he attends meetings of police officers demanding fairer wages and less grueling working conditions.
He soon becomes their leader.
Luther, in turn, is forced to flee his hometown—leaving behind a wife and child—after killing some criminals.
He arrives in Boston and finds work with Danny’s father’s family: he is blackmailed by a corrupt cop who attempts to implicate him in fabricating evidence to frame the Black community for subversive activities.

As this brief synopsis shows, the plot is remarkably intricate and packed with twists and turns, in the vein of the best American thrillers.
It culminates dramatically with the Boston Police Strike of 1919, which leaves the city at the mercy of criminals, petty thugs, and subversives for two days.
Danny emerges defeated: as the leader of the striking officers, he is accused of inciting his colleagues to abandon their posts (in reality, it was political machinations that left the city abandoned).
At the beginning of the novel, Danny believes that this world belongs to men like his father (hierarchical, authoritarian, convinced that everyone must know their place), but he comes to realize that this is neither a genuine nor a just world.

I'll tell you, Luther, it’s been a terrible year-.
Luther thought back on his own year and it made him laugh, really laugh.- What-, Danny said, Luther gave him his hand:- you and me together- What do you think you do, Danny replied, when everything you have done in your life turns out to be a damn lie? Build a new life.
I guess

Luther replied.

The most compelling aspect of the book is that a social issue—such as the great Boston Police Strike of 1919 and the birth of the American labor movement—is framed within the conventions of a thriller, making the narrative gripping and fast-paced.
Like all American thrillers, it ultimately proves verbose, redundant, and even muddled.
Many of its narrative threads get lost in the sheer mountain of pages, and the colloquial, distinctly American style fails to sustain the momentum, being far better suited to delivering plot twists than to exploring character and circumstance in depth.
Everything is left far too unresolved.

Why read it? The historical context is intriguing for us Europeans, who are unfamiliar with American history.
