A stranger walks into the Aidensfield Arms and collapses. George Ward recognizes him as Dennis Parker, who left Aidensfield and his wife and daughter seven years earlier. Parker claims he has no recollection of what has happened since he went away. He only hopes to find his family. But that may not be as easy as he thinks, because Parker is wanted for embezzling his former employer of 800£ on the day he went missing. Inspired by Hitchcock's "Strangers on a Train" Harold Jackson approaches Greengrass and wants him to set fire to his work shop. In return the Jackson will set fire to Greengrass' barn and they both can claim the insurance money. Greengrass wants nothing to do with it, but a few nights later his barn is on fire.
