Beware. Trouble is brewing. Keep a sharp lookout.

Next
night we stuck a picture, which Tom drawed
in blood, of a skull and crossbones on the front door;
and next night another one of a coffin on the back
door. I never see a family in such a sweat. They
couldn't a been worse
scared if the place had a been
full of ghosts laying for them behind everything and
under the beds and shivering through the air.
