THE POLICE DOG PINNED A CRYING 7-YEAR-OLD GIRL TO THE GROUND—THEN SHE WHISPERED SIX WORDS THAT MADE HIS OFFICER TURN PALE…

The drive to Helen’s house usually took fifteen minutes. I made it in eight, the cruiser’s tires screaming as I took the corner onto her quiet suburban street.

The streetlights flickered, casting long, dark shadows across the manicured lawns.

When I pulled up to Helen's small blue house, my stomach dropped. The patrol car I had requested to sit at the end of the street was nowhere to be seen. The house was completely dark.

Not a single light was on.

I grabbed my flashlight and unclipped Shadow’s leash, letting him run close to my side. The cool November wind whipped through the trees, making the branches scrape against the siding of the house like fingernails.

“Helen!” I yelled, pounding on the front door.

No answer.

Shadow suddenly let out a low, rumbling growl. He wasn’t looking at the front door. He was staring down the narrow side alley that led to the backyard. The hair on the back of his neck stood straight up.

I drew my weapon. “Track, buddy. Quiet.”

Shadow moved silently through the damp grass. As we rounded the corner to the backyard, the beam of my flashlight caught the glint of broken glass scattered across the patio. The back door’s window had been smashed in, the deadbolt reached through and unlocked from the inside.

My heart hammered against my ribs.

I stepped into the dark kitchen, the glass crunching beneath my boots.

“Police! Identify yourself!” I shouted.

Silence. The house was eerily still.

Shadow pulled forward, his nose to the linoleum floor, leading me toward the living room. The furniture had been overturned. Couch cushions were thrown across the room, drawers pulled out and emptied onto the rug. Someone had been searching for something in a frantic hurry.

“Helen? Ava?” I called out, my voice tight.

A muffled sound came from the hallway closet.

Shadow barked sharply and ran to the closet door, scratching at the wood. I hurried over and yanked the handle.

Helen fell forward into my arms, bound with heavy zip-ties and gagged with a piece of cloth. She was shaking violently, her eyes wide with sheer terror.

I ripped the cloth from her mouth and holstered my weapon, pulling out my pocket knife to cut the thick plastic ties binding her wrists.

“Helen, where is she? Where is Ava?” I demanded.

Helen gasped for air, tears streaming down her bruised face. “They took her, Daniel. They took my baby!”

“Who? Who took her?”

“It was a man in a ski mask,” she sobbed, clutching my jacket. “He broke through the back door. He kept asking where the key was. When I told him I didn’t have it, he grabbed Ava. He said if I ever wanted to see her again, I had to bring the key to the old rail yard at midnight.”

Midnight. I checked my watch. It was 11:15 PM.

“Did you see his face? Anything at all?”

Helen shook her head wildly. “No, but... but Ava bit him. She bit him hard on the hand, and he dropped something when he grabbed her.”

She pointed a shaking finger toward the hallway rug.

I shined my flashlight onto the floor. Sitting in the center of the patterned carpet was a heavy, silver watch. A tactical diver’s watch with a distinct scratch across the glass face.

I felt all the air leave my lungs.

I knew that watch. I had seen it every day for three years.

It belonged to my old partner, Marcus Vance.

Before I could even process the betrayal, the police radio on my shoulder cracked to life.

“Dispatch to Unit 4. We have a 10-50 major vehicle collision on Route 9. A black SUV went off the embankment. Vehicle belongs to a private investigator, Elias Thorne. No sign of the driver. Over.”

They had run Thorne off the road, and Marcus had taken the little girl.

I reached into my pocket, my fingers closing around the cold brass key Sarah had hidden beneath her daughter’s bed. Whatever this key opened, it was worth killing for.

Shadow whined, pressing his cold nose against my hand.

“Stay here, Helen,” I said, my voice hardening into steel. “Lock the door. Don't open it for anyone in a uniform. Not anyone.”

As I turned to leave, Helen grabbed my wrist with surprising strength.

“Officer Brooks,” she whispered, her eyes burning with a sudden, fierce intensity. “My daughter didn't just hide that key. She hid what the key opens. But she told me... she told me to give you a message if Marcus ever came back.”
