The note can be found in the metal box
Hey there, Tabby Kat.
I know this wasn't fair to you. I'm sorry. Everything you've done for me since Anchorage, you were the best chance I had at making a normal life again, but I just don't think it's possible for me. You deserve a life of your own.
Tell Mikey the bike is his when he gets his license next summer. She'll need a new toroidal coil soon. I'm also leaving the Commie pistol. Please, take it to dad. He'll want that. Everything else I leave to you. I know it isn't much.
I love you, Kat. Please, forgive me one more time.
