I reached into my jeans pocket and took out the small silver bike key I always kept on my truck key ring.

I laid the key on the desk, right on top of the original hardware store receipt from four months ago.

“This is the key to the lock I bought in March,” I said.

“It stayed on my truck dashboard so Noah and Lily could never reach it.”

Marcus picked up the silver key and held it up to the fluorescent light.

“And the lock found on your freezer yesterday?” Marcus asked.
