Seventies tale of police corruption featuring Terry Sneed, an amoral and ambitious young copper. He blags his way to Detective Inspector at the tender age of 26 by virtue of his native guile and a genuine talent for policing. In doing so it's suggested he loses something of himself, the man subsumed by his job.
This is very much a dry run for Newman's later Law and Order quartet and those of who've seen the films/read the books will find much they recognise here. I think Sneed goes one better than Law and Order's Fred Pyall in his unethical behaviour though with his practice of fitting up random strangers, not just the criminal fraternity, to polish his arrest record - a practice also alluded to in the recent real life Line of Duty documentary Bent Coppers. Newman was writing in 1970 so was well ahead of the game. I gather the novel is regarded as realistic in its depiction of Metropolitan police malpractice. Just goes to show not much has changed. Sneed's adventures continue in two more novels, and the play Operation Bad Apple.
