This is very much like the time I left my keys in the door when I unlocked the house, luckily the friendly Jehovah's Witnesses came and gave me free advice and crazy books, and my keys back. In this case, it's a fine brown townogy, Ephi being the religious fellow, and not some burglar who would steal all your valuables if you left the key in the door.
They also let themselves in, I think one slipped down the stairs and hurt their leg.
