This mystery is the second one published by Hillerman, after his first mystery set in Navajo country, The Blessing Way.
In the Fly on the Wall, John Cotton is a statehouse reporter and has just filed his story when a colleague comes into the pressroom. Merrill McDaniels, known as Mac, comes into file his story, but he’s a little drunk and Cotton offers to file something for him and tell his editor he went home sick. Cotton tries to get him on home but Mac says he’s celebrating breaking the story of a lifetime. Cotton doesn’t really believe him, but Mac heads on home. A few minutes later a man enters and rummages through Mac’s desk looking for his notebook, telling Cotton that Mac forgot it and sent his friend for it. A few minutes later Mac is found dead.
So begins Cotton’s at first desultory investigation into the big story Mac was working on. He finds Mac’s notebook, traces back the other man’s investigation, and wonders what Mac could have been excited about. When another reporter is killed driving Cotton’s car, Cotton at first thinks only it was an accident. He keeps digging, looking for the story while the other reporters are covering Governor Roark’s political future, Senator Clark’s plans, and small struggles over legislation. Then Cotton begins to have enough pieces to put together into a small puzzle, and he gets another warning, this one unmistakable in its meaning.
This is a masterfully plotted and steadily paced mystery that brings forward all the details of a major scam, how the players hide themselves and their cronies, and how easy it is to fool the tax payer, the reporters, and other politicians. Hillerman offers one surprise after another, and even the last two pages brings a stunning reversal. Hillerman was a journalist for many years, and his skill and experience show on every page.
