Corrupt fire marshals conspire with slumlords and insurance-claim arsonists; the Boston PD must stop them. It's not that heroic: most of the book is taken up with complaints. This is a novel of bitching, mainly about mundane things like the price of gas and groceries. Whether someone is a single Black mother living in a squalid tenement, or the entertainment agent/lawyer who owns said tenement, or the cop who investigates the owner for plotting to burn down the tenement, the outcome is the same: life is a bunch of shit that you do not need right now. The dialogue often comes in long multi-paragraph soliloquies about what a pain in the ass it is to deal with various lowlifes, often including one's wife or friends. This is a true comic novel, it's very funny, and Higgins is so perfectly attuned to the nuances and curlicues of the Boston dialect that you can hear it coming off the page. But it's not as powerful as Eddie Coyle or Cogan's Trade. There's less tension than Carter-era malaise. There's some of the gastric distress you see in The Digger's Game, but it's not as cartoonish, merely one more depressing facet of Boston life at the dawn of the Reagan era.
Stylistically, there's a lot to love. Having your moron goons latch on to a fancy word like transcend or transpire and overuse it is something that Higgins, who logged hundreds of hours listening to them on wiretaps, can put fresh life into. "A little of you goes a considerable distance." "[D]oing a lot of work on his thirst in a couple bars down on Old Colony Boulevard and Broadway, and Jimmy doesn't drink so well." The ugly, racist toughguy talk spans every possible class of society, from the lowest abetter to the bourgeois lawyer (TW!). There's also nice little descriptions, although Higgins isn't a landscape painter: the summer heat brings "long tracks of vicious-looking lightning," a violently hammered guy is "swaying very slightly." If you like the Boston tough Higgins dialogue, this book has it, although not as much as Coyle, Digger, or Cogan.
Another device he uses to good effect is lacing the dialogue between arsonist and fire marshal with banal patter between two truckers (actually undercover cops) who complain about the lack of cheese danish and the cost of engine repairs. Higgins is a dialogue man and he can overlay the real and artificial complaints to get some good ironic effect.
Higgins isn't quite as strong on his Black characters, perhaps not the biggest surprise. Initially they are only an obstacle that the entertainment attorney/slumlord Fein must overcome. Then we meet Mavis Davis, a somewhat angelic older single mother, and Fein's lone "good" tenant, whose soon Alfred is a bit of a problem. Higgins gives Mavis a multi-page soliloquy about the difficulties of life that shows she's not that different from the white crooks who are conspiring to destroy her home, and there's some good little wrinkles in her speech, but mostly she is just pure good. Her son Alfred is just not that interesting of a character, and that's kind of a problem because he winds up being very important to the plot, and it's boring when a boring character drives the plot.
I wouldn't start a Higgins newbie on this one (Coyle, duh) but it's got ample comedic dialogue and superb local touches.
