The Ink-Stained Confession. The Declan Marr Files, #1

1920s Chicago - 'When reporter Evelyn Drake turns up dead, Detective Declan Marr is assigned the kind of case nobody wants: no witnesses and no motive - at least not at first glance. The more Marr pulls at the threads Evelyn left behind, the more he uncovers a quiet network of men who move money, favors, and threats through the city without ever being seen. A network people whisper about but never name.
And they've already marked their next target. With a frightened young man on the run, a journalist who won't stay on the sidelines, and city officials warning him to walk away, Marr is forced into a corner - the kind where nothing stays clean and no help comes without a price. The only way out is to push back. In a city built on silence, Declan Marr is the one man willing to break it. Book One of The Declan Marr Files
