Maybe that dog even looked like Lucky, Harlan's childhood dog that died at the wheels of an ice cream truck.

From Stephen King's Novel "Urf"...

The rain clattered against the window, a sound like a gypsy's long fingernails tapping against a porcelain teacup. The sound was almost enough to make Harlan pretend he wasn't hearing what he heard from the hallway.

Urf. Urf.

Don't be such a child, Harlan. There is nothing in the hallway. It is just steam in the pipes, that's all: steam in the pipes.

The sound seemed to be getting closer, and as it got closer it seemed less and less human. More like a beast, a fevered dog, perhaps. Maybe that dog even looked like Lucky, Harlan's childhood dog that died at the wheels of an ice cream truck.

Urf. Urf.

It's not Lucky, Harlan. Lucky died, while children were waiting to eat ice cream treats. It cannot be Lucky in the hallway, slowly moving closer to the door...

Urf. Urf.

Urf. Urf. Urf...

I am Laslo.
