I thought my husband was the victim of a home invasion, until the suspect in handcuffs screamed a terrifying question across our lawn.

By 7:00 PM, the police tape across our front lawn had been removed, but the house felt cold and foreign.

My sister, Sarah, had driven over from the north side of town to help me with Ethan. She had made him a grilled cheese sandwich and was currently sitting on his bed, reading him his favorite story about a little blue truck until his eyes finally fluttered shut.

I sat at the kitchen island, staring at the empty space where the coffee table used to be. The living room rug was slightly bunched up near the hallway entrance.

I stood up and walked over to the rug, kicking it back with my sneaker.

The floorboards beneath were old pine, stained dark walnut. Nothing looked out of place.

I walked down the hallway to Mark’s home office. The room was dark, smelling faintly of old paper and stale coffee. His large oak desk was neat—his dual monitors sitting side by side, a stack of blueprints neatly rolled in the corner, his favorite silver pen resting on a notepad.

I sat down in his leather chair and booted up his personal desktop computer.

The login screen appeared, asking for a password.

I tried his standard variations: Ethan's birthday, our wedding anniversary, his old college football number.

Incorrect password.

Account locked.

My hands were shaking. I leaned back in the chair, running my fingers over the underside of the heavy oak desk rim.

Near the back corner, my nails caught on a small piece of rough metal.

I leaned down with my phone's flashlight, illuminating the underside of the drawer stack. Taped to the wood frame was a small, brass key—no larger than the key to a small padlock or a safe deposit box.

My heart thudded against my ribs like a sledgehammer.

I pulled the key free from the tape.

Where was the lock? We had a small fireproof safe in the master closet, but that used a digital keypad. We didn't own any brass padlocks.

Then I remembered Ethan's words from that afternoon:

“I went through the back door. I tried Mrs. Keller’s house...”

I walked out of the office, down the stairs, and into the dark basement.

The basement was unfinished—concrete walls, exposed copper pipes overhead, and rows of metal shelving holding plastic tubs of holiday decorations, old clothing, and gardening tools.

In the far corner sat an old, heavy wooden tool chest that had belonged to Mark's father. It was covered in a thick layer of grey dust, its brass latch secured with a heavy iron padlock.
