Author
David Cosgrove writes for people whose brains won’t shut up — and who suspect that might actually be a superpower. His nonfiction shows overthinkers how to transform mental chaos into clarity and momentum. His fiction sends a modern music producer back in time to work with Mozart and Beethoven. One teaches you to master your mind. The other asks what you’d create if the masters were waiting for you. Both are about the same thing: what happens when you stop fighting who you are and start building with it.

The Meridian Job (The Disaster Files Book 1)
The Meridian Job introduces Marv Slocum—a middle-aged PI with impulse control issues, a talent for being in exactly the wrong place at exactly the wrong time, and an uncanny ability to make everything worse. When Marv stumbles into a criminal conspiracy he was never meant to see, he becomes the biggest threat to a cartel operation—not because he’s smart or capable, but because he simply won’t stop showing up.
This is a dark, propulsive crime thriller with a blackly comic edge. Bodies pile up. The clock keeps ticking. And somewhere, very dangerous people are starting to realize that incompetence might actually be a survival strategy.
For readers who love the cartel authenticity of Don Winslow, the sharp-tongued antiheroes of Elmore Leonard, the Florida-noir chaos of Carl Hiaasen, and the savage wit of Duane Swierczynski. Marv Slocum didn’t ask to be a hero—he’s not even sure he qualifies as a functional adult—but he’s the one we’ve got.

No Clean Hands (The Disaster Files Book 2)
Marv Slocum shook her hand. She wiped it on her skirt. Thirty seconds later, her car exploded.
The most unlucky private investigator in Los Angeles survived the Consortium—barely. Now he’s trying to rebuild his life in a strip mall office between a yoga studio and an artisanal donut shop. Same sweaty hands. Same talent for being in exactly the wrong place at exactly the wrong time.
This time, everyone wants the Meridian Codex—a medieval manuscript with a cipher that unlocks forty billion dollars in Nazi gold. The Yakuza. The ‘Ndrangheta. A fracturing Mexican cartel hunted by a ghost called El Cuervo. They all think Marv has the key. They’re all wrong. They’re all going to try to kill him anyway.
What follows is an utterly unhinged descent into chaos: car bombs, cartel assassins, a three-day war inside a Burbank Costco, a stolen tank, and Huey Lewis playing on the radio at the worst possible moment—every single time. Also: a new assistant named June Park, three tours in Iraq, who might be the most dangerous person Marv has ever met.
The criminal underworld has a nickname for him now: The Sweaty King.
Dark humor meets relentless action—for fans of Lee Child, Don Winslow, Carl Hiaasen, and anyone who likes their hardboiled crime completely off the rails.
