Mystery of a tiny box

{That box needs some special key. We better turn to humans back. }

Aiden's words were like a command for my wolf to switch forms, even without my order. While the black fur was still covering my human body, I took the bag from my back and took a new pair of clothes out, then put it on me. I rubbed the back of my head, then turned to Aiden. He was buttoning his black shirt when I looked at him. 

"Where do we need to look for that key? It wasn't in my father's diary and in that teddy too." 

Aiden took out a pack of cigarettes, took one out, put it in his hands, and lit it up with a lighter. He inhaled smoke, took a deep breath, then exhaled it into the air. His fingers slipped into the pocket of his gray jeans and took out some small package. It looked like something small, maybe even a key, wrapped in an old napkin or piece of cloth. I arched an eyebrow but kept silent.
