Some people just can't die in a neat and orderly fashion. Their wills, the listing of their last wishes, have gone missing and as a result their possessions are being fought over. Sometimes the will has been intentionally hidden to keep it out of the wrong hands. Sometimes it's been stolen by someone who wants to get something out of it. Sometimes it's just been misplaced.
