A tale of two men

A shapeshifter came to town as a box. When unloaded at the station he transfigured and walked through town. People were not nice here and they had caught and condemned an innocent man.

The shapeshifter broke into jail, sent the innocent man to parts unknown and took his place. That day he was hanged. He hung there and looked purple. Next night he changed to an assistant, dragged up a coffin, filled it with dirt and in daylight helped the town to bury it.

He was finished, He turned into a box with a far away label at the station.
