Comfortable that your gun is in easy reach, you pull up closer to the house, angling to get a better look at the pair. Unfortunately, the moment it took to check your holster left them the opportunity to quickly abandon their spots on the porch, disappearing into the farm house.

It certainly seems likely, the more you think about it...
