Circumstantial

Shoes have mysteriously disappeared in our house over the past few months.  There are no leads as to what is happening to them.  You'll simply go to put on your favorite pair and one, if not both, will no longer be where you left them.  Oftentimes, when you do find them, they have been vandalized by slobber and occasionally have bite marks.. Today, I think I may have gotten a major break in the case.  I'm sure in a court of law, this evidence would be considered circumstantial.  That said, this house is no court of law.
