Chapter 1

• I’d been listening in on other people’s secrets. So far, more than twelve hundred of them.
• But today was different. What I heard wasn’t a secret. It was death.
• I was a hydrology tech with the Riverton City Water Resources Department.
• I worked at the river monitoring station about two miles downstream from Greenwood Dam. Every day, I logged water level, flow rate, turbidity, and keep an underwater sonar array—fifteen years old and cranky—running.
• That array was built to track fish migration. Then three years ago, after a software update, it started picking up something else.
• Human voices.
• Not speech.
• But the sound a body would make when it sunk and the vocal cords shivered one last time.
• Muffled. Short. Like a rock hitting a mud pit.
• Or like someone trying to scream underwater, with the river water flooding the throat and grinding the words to mush, leaving just one frequency—somewhere between 400 and 600 hertz, lasting 0.3 to 0.8 seconds—then dropping to zero.
• I knew exactly what it was.
• I’d heard it more than twelve hundred times.
• Every time a body drfited from upstream and passed the sonar array, the system would flag the strange vibration in the water and save a voiceprint file.
• For three years, this river had delivered an average of about 1.1 bodies a day—jumpers, drownings, the ones tossed in, and the ones no one would ever identify.
• I numbered them and stored them on a hard drive. I never called the cops.
• Not because I was cold-blooded.
• But because those recordings could be sold.
• Three years ago, my daughter Sophia had been diagnosed with retinoblastoma. The disease had taken her right eye. Her left needed proton therapy. At John Hopkins Hospital, the total ran about $280,000.
• As a contractor at a river station, I'd make $2,200 a month. I could work till I drop and never scrape that together.
• My ex, Hannah, left with the kid. She worked at a gas station for $1,800 a month. She couldn't even cover Sophia’s follow-up visits.
• So I came up with a plan.
• To most folks, these voiceprints were meaningless—just messy waveforms.
• To some people, they were worth a fortune.
• Say a husband killed his wife, drove out to a bridge in the sticks at midnight, and threw her into the river.
• He'd think nobody would ever know. He'd think he’s in the clear.
• What he didn't know was that the station’s beat-up sonar caught her last scream the instant she hit the water.
• That voiceprint could nail him—if it landed in a cop’s hands.
• It could also save his ass—if someone “took care of” the file.
• I’d taken care of it. Plenty of times.
• Deleted the voiceprint. Changed the timestamp. Forged the raw data.
• Five grand to fifty grand a job, depending on what they could pay and how bad the mess was.
• In three years, I’d handled forty-seven “orders.”
• A construction company boss. A Vegas nightclub operator. A section chief over at Riverton City Hall. One of them was a state trooper.
• I never asked their names. They never asked mine.
• I stashed the money in a dedicated account. Password’s Sophia’s birthday.
• Right now I was sitting on about $230,000.
• I was only fifty short of what I need, and today was the day I'd close that gap.
• But the order I got was different.
