Tell Me the Tale

Your Grandmother died and your Aunt Mary asked you to come and help clear out the house. When you get there, she is working in the attic. She's sitting on a stool and rummaging through a huge trunk and invites you to take the other stool and help her. 

The first thing you pull out is an old manila envelope that appears to be filled with papers. You dump them out and a legal-looking document and several photos fall into your lap. The photo at left is the first photo you pick up. 

You turn to Mary and ask her about it. She glances at it and pales.

So, tell me the tale.
