Immediately!

Assume you are the only one “minding the store.” If is very possible that a neighbor has a key to the deceased’s house and that his honesty has evaporated. Your cousin is on her way right now to claim the pretty ring she has coveted since childhood. The tools are lying around the garage, and the neighbor who once drove the deceased to the store still has keys to the car.  The prized bird dog just had pups!  Your ne’er do well cousin just came to town… broke.

You are in charge now.
