" Something was trying to dig its way beneath the wall and into the garage, practically right underneath my butt. I felt a chill of fear, followed swiftly by anger at the thing that had added to already overabundant flow of adrenaline. I clutched my make-shift weapon in hand and moved to crouch over the source of the disturbance, lifting in preparation to strike at whatever came through.

I saw it in the dimness, and there was no mistaking the shape. A paw, a huge canine paw, scrabbled at the earth, digging out a shallow hole beneath the wall, frustrated by bits of concrete that got in the way. Between shots, I could hear animal sounds outside, panting whimpers of eagerness, it seemed. Whatever was out there wanted to dig its way inside, and wanted it bad.

"Dig this," I muttered, and swung the wrench down on the paw, hard. "
