Look for clues

"What would Velma do." I thought to myself. "Look for clues!"

I began to inspect the area where my case had been. There were marks on the carpet where it had been dragged! And they led straight to the door! Maybe this wasn't a ghost afterall, maybe it was one of the gang pranking me!

I also found a strand of orange fabric. It could have been from Velma's sweater or Fred's ascot.
