“Nobody flips on me.”

He said it with such authority, an alarm sounded in Vaughn’s mind. Junior was the leader of the group, not Baltierra and definitely not Jimmy de Luca. “Especially a dead man.”

Junior didn’t flinch. His eyes didn’t register surprise or remorse. Maybe—and this could’ve been Vaughn’s imagination—they took on a hint of satisfaction.

“It’s too bad about him, really. Freak car accident,” Vaughn continued as he pulled into the jail’s underground parking and prisoner transfer station. “If my gut’s correct, you have better odds of surviving while you’re in my jail than you would on the street, because I have a feeling El Diente’s cleaning house.”

He twisted in his seat to smile condescendingly at Junior, who wouldn’t meet his eye. “That’s who you work for, right? El Diente, the new drug cowboy in town?” He faked speculation, scratching his chin and rolling his eyes to the car’s ceiling. “Hmm. I sure hope he doesn’t get the wrong impression that because I’m on the street tossing his name and your name around together that you flipped on him and gave me his name. I don’t think he’d like that, do you?”

“I’ve got nothing to fear from El Diente.” The way he said it, coupled with the smug look on his face, Vaughn believed him.

“Any time you want to chat about El Diente or Baltierra, you let me know. District attorneys and judges appreciate a man who steps up to help us catch more bad guys. Never know what kind of deal your cooperation might get you.”

A gate closed behind his car, sealing the entrance. Still, Kirby and Molina set up position on the street. Four prison guards met them and waited curbside with cuffs and a fresh wheelchair. He stepped from his car and saluted the guards as he walked around to the passenger side. The guards stepped forward with the shackles and wheelchair.

He opened Junior’s door with a flourish, then stepped aside to let the guards have access. “Welcome to your new home, son. On behalf of the Quay County Sheriff’s Department, I hope you enjoy your stay.”

“Rachel? You need to take a look at this.”

Ben stood in the dry canal, leaning against the grate that separated the canal sections. He’d pried off the lid to the electronics and was attempting to open the flow valve. He’d sworn to her he was mechanically minded and could most likely fix it without calling in an electrician, but he’d been working for over an hour in the hazy glow of early morning, and it looked to Rachel like all he’d accomplished was coating himself in a thick layer of sweat and dust.

Rachel stood a half acre away, shoveling muck onto the embankment so that once they started the water flow, the debris wouldn’t get snagged in the grates and create a dam. It was hard work, and now that the sun had crested the land to the east, the temperature was climbing. According to Rudy, the air would touch ninety-five degrees or more. In other words, the labor and heat were the ideal remedy for the foul mood Vaughn had left her in the day before.

“Did you figure out why you’re having so much trouble?” she called.

“Yes. It’s a little tough to get a flow valve working if it’s not actually a flow valve.”

Huh? Propping her shovel against the canal wall, she slogged to where Ben stood. “What do you mean? What else could it be?”

The air around Ben stunk, like a dead animal was rotting in a nearby bush. The entire flow mechanism had been removed and sat on the embankment. Where it had been sat a dark, square hole that disappeared into the earth. “Ugh. That smell is something awful.”

“The machinery was tampered with so that it looked like a flow regulator, but when I pried the vents off, I could tell right away that’s not what it is.”

“Go on.”

He leveled an earnest gaze at her. “You’re not going to believe me, but it’s a swamp cooler.”

“What? That’s crazy.”

“Rachel, ma’am, I know machines. This is a swamp cooler.”

“Why would anyone do that?”

Squinting into the sun, he shrugged. “Beats me. Who had access to it around the time the canal stopped pumping?”

“Only me and my dad. Technically, Jenna had access too, but she never had the temperament for farm work.”

“Any farmhands?”

“No, by then we’d let them all go.”

He scratched his head under his hat. “I can’t see any reason why a farmer would tamper with his own equipment, especially something as important as the main irrigation canal. Especially to go to the trouble of jury rigging a swamp cooler to look like a flow mechanism.”

“I’m telling you, Ben. You have to be wrong about this. What good would a swamp cooler do out here in the middle of nowhere? There’s nothing to cool.”

Ben looked at the canal. He stomped the heel of his boot against the concrete. “Could be my imagination, but that sounded hollow.”

Rachel threw up her hands. “Oh, now there’s a secret room underneath the canal. Great theory. Where’s the door?”

Rubbing his chin, Ben looked around. Rachel followed his gaze. In the dirt adjacent to the canal sat the covered box of the pump that took water from the canal into the field. The second Ben zeroed in on it, Rachel’s stomach dropped. A nagging voice told her he was on to something, despite how preposterous the idea was.

Ben pulled himself out of the canal, then offered his hand to Rachel. She accepted his help and followed him to the pump.

He pulled the lid off the box, and Rachel expected to see a hole or a hatch, but all she saw was the pump.

“Nice try,” she said.

He squatted and tinkered with some of the parts, his brow furrowed in concentration. Then he stood, wiped his hands on his jeans, and pulled the entire pump system up while Rachel gasped in shock.

The tops of the pump valves and tubes had been bolted to a steel plate. They weren’t connected to anything. A façade. Beneath it, a hole that disappeared into darkness. And it stunk so bad of chemicals and rot that Rachel’s eyes watered and her stomach threatened to unload its contents. As a born-and-bred farm girl, she’d spent her life around unpleasant smells, so turning her stomach was a tough ticket to sell.

What have you done, Dad?

From his back pocket, Ben grabbed a flashlight and pressed it into her hand. “I suppose we ought to look inside.”

She wanted to say no. She wanted to say, Cover it up and let’s pretend this doesn’t exist, but there’d been too many secrets on this farm already, and she’d had enough. She dropped to her belly and peered into the space with the flashlight.

The walls were lined in concrete and angled toward the canal.

Too numb to think, she stood and handed the flashlight to Ben. He lay flat and ducked his head inside. “Any ideas why it was built?” he asked. “Maybe a fallout shelter or something?”

Rachel hugged herself and looked at the clouds on the horizon. “He wasn’t the type of man to see a need for a fallout shelter. He was more of an eternal optimist type.” Then again, she was beginning to feel like she didn’t know him well at all. Her hair stood on end. Something was wrong. Never mind the whys of it—when would he have had the opportunity to build an underground passage, complete with swamp cooler, without Rachel knowing? It would’ve taken at least a week and a whole construction crew, depending on the size.

It hit her in a flood of memory. After the water stopped in this field and the alfalfa crop died off before it was ready for harvest, her dad had put her to work in the fields on the east side, and when she’d made noises about getting back to the west side fields to fix the canal, he’d sent her to a week-long agriculture convention in Colorado. She’d crowed that they couldn’t afford it, and that the money would be better spent fixing their irrigation system, but he’d been adamant, and she’d dreamed of taking a vacation for years, so she went along with it.

But still, wouldn’t she have noticed when she returned that the ground around the canal was disturbed?

Maybe the structure was older than she was assuming.

“This canal runs the entire western and southern length of our farm. My dad built it when I was a kid to replace the antiquated system his father had used since the early fifties. I wonder if this is the only hidden set-up like this.”

“Easy to find out, now that we know what to look for. Let’s go down there and check it out. Maybe it’ll give us some clues about why your dad built it.”

They’d driven in Ben’s truck that morning. He walked to it and found a second flashlight. He left his hat sitting on the seat of the cab. Rachel walked over and did the same. “One more thing,” he added, digging under the seat.

He brought a rifle out. “My dad taught me to always be prepared.”

“Like a Boy Scout farmer?” It was easy to joke because the rifle made her feel better, as did Ben’s presence. But she was still rattled to the core by their finding.

He loaded rounds into the chambers. “Boy Scout farmer—I like the sound of that. Let’s check out the tunnel.”

He squeezed through the narrow opening first. His broad, brawny body almost too big to fit. She handed his rifle down to him, then followed, grateful she wasn’t claustrophobic like Jenna because they were standing in a narrow tunnel barely wider than Ben’s shoulders.

He shone his flashlight in, and Rachel’s beam of light joined with his. The stench of rot made her dizzy. She plugged her nose. Ben did the same, taking the lead through the tunnel.

Twenty paces in, the tunnel opened into a low-ceilinged, long concrete lined room about the size of their kitchen with doors on either side that led into more darkness. Rachel shone her beam of light over the ceiling, searching for where the swamp cooler vent would be. She found one in the upper left corner, then another vent on the right. They were standing directly beneath the irrigation canal.
