Sunk Costs - Lang Preston

Dan is a con man and a drifter just looking for a ride east. A strange woman in a business suit picks him up on the highway, and soon they’re going 70-miles-an-hour and she’s got a gun pointed at his head. Instead of shooting him, she hits him with a proposition to make some fast money. Against his better judgment, Dan sneaks into her office and steals the key to a safe deposit box. He thinks he’s made a clean getaway until he’s stopped on the way out by Kate, a sultry accountant who knows something is up and is looking for a way in on the score.

Kate offers Dan a better deal, and the two figure out a way into the box. But there’s no money inside. What they do find is enough to track down a shady photographer who holds the promise of even more treasure. But deception, misdirection, and murder keep Dan on the run, as he begins to realize that Kate the office drone is not what she seems, and the lady on the highway who he double-crossed may be the most dangerous criminal he’s ever met.
