A ghost has been the regular nightly visitor at a certain house so long that the occupants have gotten used to it. Three crooks, reading an account of it in the newspaper, decide, each unknown to the other, to go and impersonate the ghost long enough to rob the house, knowing that the occupants will take no heed of the presence of the ghost. The scheme might have worked, but there were too many playing the game, so one landed in the "cooler."
